1. Growth Hormone (GH):
a) Also known as somatotropin, GH stimulates growth, development, and tissue repair.
b) GH release is regulated by growth hormone-releasing hormone (GHRH) and growth hormone-inhibiting hormone (GHIH, somatostatin).
2. Prolactin (PRL):
a) Prolactin plays a significant role in stimulating milk production in women after childbirth.
b) Its release is regulated by prolactin-releasing hormone (PRH) and prolactin-inhibiting hormone (PIH).
3. Adrenocorticotropic Hormone (ACTH):
a) ACTH stimulates the adrenal glands to produce cortisol, a hormone involved in stress responses and energy mobilization.
b) ACTH release is controlled by corticotropin-releasing hormone (CRH) from the hypothalamus.
4. Thyroid-Stimulating Hormone (TSH):
a) TSH regulates the thyroid gland's activity, promoting thyroid hormone production.
b) TSH release is controlled by thyrotropin-releasing hormone (TRH) from the hypothalamus.
5. Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH):
a) FSH and LH are gonadotropic hormones involved in regulating reproductive functions.
b) FSH stimulates follicle development and maturation in women and stimulates sperm production in men.
c) LH triggers ovulation in women and stimulates testosterone production in men.
d) FSH and LH release is controlled by gonadotropin-releasing hormone (GnRH) from the hypothalamus.
6. Antidiuretic Hormone (ADH, Vasopressin):
a) ADH regulates water reabsorption in the kidneys, maintaining blood volume and electrolyte balance.
b) ADH release is triggered by changes in blood pressure, blood volume, and osmolality.
7. Oxytocin:
a) Oxytocin plays a role in stimulating uterine contractions during childbirth and milk ejection during breastfeeding.
b) Oxytocin release is triggered by physical stimulation, stress, and social bonding.
8. Melanocyte-Stimulating Hormone (MSH):
a) MSH regulates skin pigmentation by controlling the production of melanin.
b) MSH release is influenced by sunlight exposure and certain neuropeptides.
It's important to note that the release and regulation of these hormones are intricately connected with various feedback loops and signals from the hypothalamus and other endocrine glands, ensuring a delicate balance and coordination within the endocrine system.
