Study Notes
Homeostasis and Hormonal Regulation
- The hypothalamus integrates functions that maintain chemical and temperature homeostasis in the body.
- Hypothalamic releasing hormones are synthesized in the hypothalamic neurons.
Transportation to the Anterior Pituitary
- Releasing hormones are transported to the anterior pituitary through the hypophyseal portal system.
Factors Influencing Hormonal Secretion
- Various physiological factors, including stress, light, and feeding cycles, influence the secretion of hypothalamic releasing hormones.
Anterior Pituitary Nomenclature
- Another name for the anterior pituitary is the adenohypophysis.
Hormone Synthesis
- Anterior pituitary hormones are synthesized by endocrine cells under the regulation of hypothalamic hormones.
Growth Regulation
- Growth hormone (GH) is primarily responsible for regulating body growth and plays a crucial role in metabolism.
Major Source of IGF-I
- The liver is the major source of Insulin-like Growth Factor I (IGF-I), which mediates growth hormone effects.
Adrenal Cortex Regulation
- Adrenocorticotropic hormone (ACTH) stimulates cortisol secretion by the adrenal cortex and promotes the growth of the adrenal cortex.
Insulin Sensitivity and Anabolic Effects
- Growth hormone decreases insulin sensitivity in muscle and acts as a protein anabolic hormone, enhancing protein synthesis.
Female Hormonal Development
- Prolactin stimulates breast development in females and regulates the secretion of female sex hormones from the ovaries.
Ovulation and Testosterone
- Luteinizing hormone (LH) stimulates ovulation in females and prompts testosterone secretion from Leydig cells in males.
Estrogen and Sperm Production
- Follicle-stimulating hormone (FSH) stimulates the secretion of estrogen by the ovaries and is essential for sperm production in males.
Regulation of TSH and Prolactin
- Thyrotropin-releasing hormone (TRH) stimulates the release of thyroid-stimulating hormone (TSH) and prolactin from the anterior pituitary.
Prolactin Inhibition
- Dopamine inhibits the release of prolactin, maintaining balance in lactation and reproductive hormonal functions.
