How does one identify the location of the pituitary gland in the brain?
The pituitary gland, also known as the hypophysis, is a small, pea-sized gland located at the base of the brain. It is often referred to as the “master gland” because it controls the function of other endocrine glands in the body. Despite its small size, the pituitary gland plays a critical role in maintaining a wide range of bodily functions, including growth and development, metabolism, and…

Many neuropeptides were originally identified as pituitary or gastrointestinal hormones Probably the first neuropeptide to be identified was vasopressin, a nine-amino-acid peptide secreted by the nerve endings in the neural lobe of the pituitary. The source of the vasopressin is the magnocellular neurons of the hypothalamus, which send axons to the neurohypophysis, which is the site of release into the blood, in classic neurosecretory fashion. Like vasopressin, a number of gastrointestinal peptides, such as cholecystokinin (CCK), are also found at high concentrations in the nervous system. In the gastrointestinal (GI) system, CCK is secreted by the duodenum and governs the delivery of digestive enzymes and bile acids into the intestine. In contrast to vasopressin and CCK, the hypothalamic releasing factors are peptides released into a special portal blood system that bathes the anterior pituitary, controlling the secretion of pituitary hormones. In this system, “portal” means two successive capillary beds, one in the hypothalamus and one in the anterior pituitary. Substance P was first purified as a “sialogogic peptide,” causing salivation in a bioassay. Now substance P is recognized as a major bioactive peptide in many neuronal pathways, including pain signaling. Since there are so many peptides, this chapter focuses on the principles of how neuropeptides are synthesized, stored and released and how they act on the cells they regulate. Comparisons among peptides and smaller, “conventional” neurotransmitters will be emphasized. It is significant to note that the number of known neuropeptides far exceeds the number of classical neurotransmitters.

Vasopressin is a nonapeptide that is produced in the paraventricular and supraoptic nuclei of the posterior hypothalamus as a prohormone. It travels down the supraoptic hypophyseal tract, attached to the carrier protein neurohypophysis, to the axonal terminals of magnocellular neurones in the posterior pituitary. Takes 1-2 hours for synthesis, delivery, and storage. 4 pg ml-1 are the normal plasma values. It is broken down by vasopressinases, which are present in the liver and kidney, and has a half-life of 10-35 minutes. Vasopressin impurities interact with oxytocin, V1, V2, and V3 type receptors (OTR).
Vascular smooth muscle in the systemic, splanchnic, renal, and coronary circulations contains V1 receptors. They can be found on platelets and myometrium as well.
The pituitary is the primary location of V3 receptors. They are Gq-coupled G-protein receptors, and when they are active, they raise intracellular calcium. They are believed to play a role in the production of ACTH and may function as a neurotransmitter or mediator in the consolidation or retrieval of memories as well as the control of body temperature. 1, 2

Human Hormones and their properties
The Endocrine System is the collection of glands and organs that produce hormones which helps in the chemical co-ordination and integration in the human body. The following image shows various glands and their hormones. 
Tumblr media
Properties of hormones
These are discharged by endocrine organ (biogenic in source).
Their discharges is delivered straightforwardly into blood (aside from nearby hormones for example gastrin).
These are conveyed to remotely find explicit organs, called target organ.
These have explicit physiological activity (excitatory or inhibatory). These co-ordinate diverse physical, mental and metabolic exercises and look after homeostasis.
The hormones have low sub-atomic weight for example ADH has an atomic load of 600–2000 daltons.
These demonstration in extremely low focus for example around10–10 molar.
Hormones are non antigenic.
These are generally fleeting. So have a no camulative impact.
Some hormones are snappy acting for example adrenalin, while some acting gradually for example ostrogen of ovary.
Some hormones emitted in dormant structure called Prohormone for example Favorable to insulin.
Hormones are explicit. They are transporters of explicit data to their particular objective organ. Just those objective cell react to a specific hormone for which they have receptors.
Pituitary Gland (Hypophysis)
(1) Pituitory is known as hypophysis cerebri, its name pituitary was given by vesalius.
(2) Muller's organ of amphioxus and subneural organ of hardmania is homologous to pituitary of vertebrates.
Parts and segment
(1) Adenohypophysis (Anterior projection)
Pars distalis
Pars tuberalis
Pars intermedia
(2) Neurohypophysis (Posterior projection)
Pars nervosa
Infundibulum
Hypothalamus
1.    Position and Structure: Hypothalamus is the floor of diencephalon. It is shaped of masses of dark issue, called hypothalmic cores, containing neurosecretory cells. It is associated with front pituitary projection by blood vessels of hypophyseal entryway framework and with the back pituitary flap by axons of its neurons, both going through the pituitary tail.
2.    Hormones of hypothalamus: Neurosecretory cells of hypothalamus emit neurohormones called delivering factors (RF) or restraining factors (IF). These neurohormones are conveyed by hypophyseal gateway framework to adenohypophysis (essential objective organ) and animate or restrain the arrival of trophic hormones from adenohypophysis. These neurohormones are proteinous in nature and shaped of 3 – 20 amino acids.
Thyroid organ
1.    The name "thyroid" was presented by Thomas Wharton (1656).
2.    It is gotten from Greek "Thyreos" a shield.
3.    Location: This is the biggest endocrine organ of our body. It is situated in our neck upon the ventral part of larynx (sound box or Adam's apple) and a couple of foremost most tracheal rings. It is a dim earthy colored and H-molded bilobed organ.
4.    Hormones of thyroid:
Thyroid organ secretes two iodinated hormones.
(a) Thyroxine: It is an iodine containing (6% iodine) amine hormone which is gotten from tyrosine amino corrosive. Chemically thyroxine is tetraidothyronine however likewise found as tri-iodothyronine. Emission of thyroxine is contrarily relative to the blood level of thyroxine (criticism system).
(b) Thyrocalcitonin (TCT): It is a long peptide hormone discharged by parafollicular by cells of thyroid organ (C-cells). It discharge is managed by expanded plasma level of calcium by criticism instrument.
5.    Irregularities of thyroid organ
(a) Hypothyroidism: (Decreased segment of thyroxine from thyroid organ).
(b) Hypersecretion of thyroid hormones (Hyperthyroidism or thyrotoxicosis) : This may likewise be a hereditary imperfection, however for the most part it is given by interminable contaminations (flu, stiffness, tonsilitis, tuberculosis, measles, challenging hack, and so on.) pregnancy, admission of huge dosages of iodine, over-eating, and so forth. It results into an extensive increment in glucose and oxygen utilization by cells and the pace of oxidative digestion in the mitochondria.
Parathyroid organ
1.    Hormones of parathyroid: Active hormone emitted by parathyroids is parathormone (PTH), additionally called Collip's Hormone (Phillips collip, 1925).
2.    Irregularities of parathormones
       (a) Hypoparathyroidism (Hyposecretion of parathormone)
       (b) Hyperparathyroidism (Hypersecretion of parathormone)
Pancreas
1.    Hormones of pancreas and their job:
(a) Insulin: Insulin manages how the body uses and stores glucose and fat.
(b) Glucagon: This is discharged by the alpha cells of islets of Langerhans. Its capacity is to hoist glucose level in blood when glucose is insufficient.
(c) Somatostatin and Pancreatic polypeptide: Modern physiologists have proposed that the d and F (PP) cells of pancreas separately discharge somatostatin (SS) and pancreatic polypeptide (PP). Somatostatin takes after the development hormone inhibitory hormone (GHIH) emitted by hypothalamus.
Thymus organ
1.    Function of thymus organs
Thymus is haemopoietic, just as, an endocrine organ.
The significant capacity of thymus is to emit thymosin hormone, thymic humoral factor (THF), thymic factor (TF), thymopoietin.
Thymus is basic in neonatal (recently conceived) baby and postnatal kid for ordinary advancement of lymphoid organs and cell invulnerability.
Gonads
1.    The gonads are the sex organs, the testicles and the ovary.
(i) Testes
The testis structure part of the male conceptive framework, and is where sperm and testosterone are created.
Elements of Testes
It animates the male conceptive framework to develop to full measure and become utilitarian.
It invigorates the arrangement of sperms (spermatogenesis) in the seminiferous tubules.
It additionally decides the male sexual conduct sex encourage, forceful conduct.
Under its impact protein anabolism increments.
(ii) Ovary
The ovary is a ductless conceptive organ in which the female regenerative cells are delivered.

‪🇺🇸 Patriotic Pituitary 🇺🇸‬
‪There's a little Red (acidophils) White (chromophobes) & Blue (basophils) in us all!‬
‪Happy 4th of July everyone!

———
The pituitary gland (hypophysis) is the king of the endocrine glands! It is so important that it sits in its own throne on the floor of the skull called the sella turcica where is sends out hormones to control the entire body via the blood stream.
It has two distinct parts:
An anterior pituitary (adenohypophysis) which is glandular and colorful and a posterior pituitary (neurohypophysis) which is pale and subdued because it is composed of the axons of nerves that reside in the hypothalamus of the brain.
The patriotic adenohypophysis (shown here) constantly flies its red, white and blue flag. Cheering on the organs of the body by sending them signalling molecules.
The red cells are acidophils: they make Growth Hormone (to urge our bodies to grow) and Prolactin (to make sure milk is produced during pregnancy).
The white cells are chromophobes: they don’t have a clearly understood function in the pituitary.
The blue cells are basophils: they produce Thyroid Stimulating Hormone (TSH - which excites the secretory cells of the thyroid gland), Follicle Stimulating and Luteinizing Hormone (FSH, LH - these are important in reproductive processes in the body) and Adrenocorticoptrophic Hormone (ACTH - which excites the secretory cells of the adrenal cortex).

Intranasal Spray of Oxytocin Might Improve Working Memory Performance in Alzheimer, Tracking with Diffusion Tensor Imaging by Fatemeh Bakouie* in Biomedical Journal of Scientific & Technical Research https://biomedres.us/fulltexts/BJSTR.MS.ID.001818.php
Alzheimer's disease (AD) is a neurodegenerative process; manifests as episodic memory loss and working memory impairment [1]. Prefrontal cortex plays a key role in working memory which depends on modulating transmitters, dopamine and gamma-aminobutyric acid (GABA) [2,3]. The neurohypophysial hormone, oxytocin acts on lactation, parturition, modulating stress responses, pain perception, learning and different aspects of social behavior. Investigators suggest that oxytocin has potential therapeutic effects on depressive disorders because it induces hippocampal neurogenesis- a process altered in depression [4]. In this regard intranasal oxytocin administration found to be the most effective way to access to the central nervous system [5]. Dopamine concentrations in Alzheimer patients decreased (about 18-27%) in temporal and hippocampal cortices [6]. In addition to dopamine, significant reduction in GABA level has been identified in AD [7]. A recent study suggested that administration of single oxytocin dose has improved "executive component" of working memory (component contributing in information maintenance plus manipulation) in schizophrenic patients [8]. One of the oxytocin analogues induces GABAergic transmission [9]. Prefrontal cortex dopamine amounts might multiply upon oxytocinergic stimulation.

I took a test today in my human anatomy class for the lab. One of the classes had a human head with a midsaggital cut, with a pin stuck into the fleshy contents of the sella turcica, basically asking 'what is this' The pituitary gland. Good old buddy pituitary gland. But I could not FUCKing think of the word pituitary! I'm sitting there, like ... it's not the pineal gland ... it's not the pulmonary gland, that's not even a thing ... So what I end up putting for my answer is 'the gland inside the sella turcica, connected to the hypothalamus by the infindibulum, aka hypothalamal-hypophyseal tract; also known as the neurohypophysis (well half of it is) ... but I cannot think of the FREAKING name! It starts with a p and I'm writing down all of the information I know about it in hopes for half credit =( ' And then I drew a picture of the pituitary gland,2/3s of it labeled 'neurohypophysis' and the other part 'adenohypophysis', with a stalk leading out with an arrow saying 'to hypothalamus,' with "WHAT IS YOUR NAME" written near it.

The Patriotic Pituitary There’s a little Red (acidophils), White (chromophobes) and Blue (basophils) inside each and everyone of us!

The pituitary gland (hypophysis) is the king of the endocrine glands! It is so important that it sits in its own throne on the floor of the skull called the sella turcica where is sends out hormones to control the entire body via the blood stream.

They make Growth Hormone (to urge our bodies to grow) and Prolactin (to make sure milk is produced during pregnancy).
The White cells are chromophobes:
They don’t have a clearly understood function in the pituitary, but are perhaps a stem cell population for the other pituitary cells.
The Blue cells are basophils:
They produce Thyroid Stimulating Hormone (TSH - which excites the secretory cells of the thyroid gland), Follicle Stimulating and Luteinizing Hormone (FSH, LH - these are important in reproductive processes in the body) and Adrenocorticoptrophic Hormone (ACTH - which excites the secretory cells of the adrenal cortex). 
 Happy 4th everyone!
