Study Notes
Anterior Pituitary Hormones
- The anterior pituitary gland secretes multiple hormones, including TSH (thyroid-stimulating hormone), LH (luteinizing hormone), FSH (follicle-stimulating hormone), and hCG (human chorionic gonadotropin).
- All of these hormones share a common subunit.
Proopiomelanocortin Derivatives
- Proopiomelanocortin is the precursor protein for several hormones, including ACTH (adrenocorticotropic hormone), β-endorphin, and α-, β-, and γ-melanocyte-stimulating hormones (MSH).
Posterior Pituitary Hormones
- The posterior pituitary gland secretes vasopressin (ADH) and oxytocin.
- These hormones are produced in the hypothalamus and transported to the posterior pituitary gland.
Pituitary and Adrenal Gland Development
- The anterior pituitary gland develops from oral ectoderm.
- The adrenal gland develops from mesoderm.
Hormone Production Regulation
- Aldosterone production is regulated by the renin-angiotensin-aldosterone system.
- Corticotropes in the anterior pituitary gland produce adrenocorticotropic hormone (ACTH), which regulates glucocorticoid production in the adrenal cortex.
Pancreatic Hormones
- The endocrine pancreas contains α, β, δ, and PP cells, responsible for producing glucagon, insulin, somatostatin, and pancreatic polypeptide, respectively.
Hormone Functions
- Vasopressin (ADH) regulates water reabsorption in the kidney.
- Prolactin stimulates lactogenesis.
- Somatostatin inhibits growth hormone (GH) secretion.
- Oxytocin stimulates uterine contractions during labor.
- Prolactin is suppressed by hyperprolactinemia.
- Melanocyte-stimulating hormone (MSH) regulates melanogenesis.
- Oxytocin is involved in modulation of fear, anxiety, social bonding, mood, and depression.
- Prolactin is responsible for delayed postpartum ovulation (natural contraception) during breastfeeding.
- Elevated prolactin levels can cause galactorrhea (abnormal milk production).
- Corticotropin-releasing hormone (CRH) stimulates the secretion of ACTH and β-endorphin.
