Study Notes
Adrenal Cortex Functions
- Mineralocorticoids Production: The zona glomerulosa of the adrenal cortex produces mineralocorticoids, primarily Aldosterone.
- Glucocorticoids Function: Glucocorticoids, produced in the zona fasciculata, mainly regulate metabolism, promote gluconeogenesis, and help in response to stress.
- Androgens Production: The zona reticularis of the adrenal cortex is responsible for producing androgens or sex steroids.
- Mineralocorticoids Function: Aldosterone helps maintain electrolyte balance and regulates blood pressure by increasing sodium retention and potassium excretion.
Pancreatic Islets
- Main Function of Cells: The pancreatic islets, also known as Islets of Langerhans, primarily regulate blood glucose levels.
- Insulin Production: Beta cells in the pancreatic islets produce insulin, a hormone crucial for glucose metabolism.
Hypothalamic Functions
- ADH Function: Antidiuretic hormone (ADH), produced by the supraoptic nucleus, primarily regulates water balance and reduces urine output.
- Oxytocin in Childbirth: Oxytocin stimulates uterine smooth muscle contractions during childbirth and is produced by the paraventricular nucleus.
- Storage Location: Both ADH and Oxytocin are stored in the posterior pituitary gland before their release.
Hormonal Regulation
- Oxytocin's Role: Besides childbirth, Oxytocin is involved in milk ejection during lactation and may promote bonding and social behaviors.
- ADH Production Stimulus: The main stimulus for ADH production includes increased plasma osmolality and low blood volume.
Adrenal Gland Development
- Neural Crest Origin: The adrenal medulla arises from neural crest cells during development.
Pituitary Gland Characteristics
- Acidophils Staining Properties: Acidophils in the pituitary gland typically stain red or pink, indicating their affinity for acidic dyes.
- Hormone from Thyrotrophs: Thyrotrophs primarily produce Thyroid Stimulating Hormone (TSH), which regulates thyroid function.
- Basophils Staining Properties: Basophils in the pituitary gland appear blue or purple when stained, due to their affinity for basic dyes.
