Flashcards in Maternal Adaption of the CNS and Endocrine System Deck (16):
What is "placenta brain"?
The brain shrinks during pregnancy and returns to normal by 6 months post partum. This causes some women to experience memory loss and lack of concentration
Name the TEN major components of the female endocrine system
Thyroid and Parathyroid Glands
Pancreatic Islets of Langerhans
Which hormone is released from the hypothalmus and what does it do?
Stimulates release of luteinising hormone and follicle stimulating hormone
Which TWO hormones are released from the posterior pituitary gland and what do they do?
Anti-diuretic hormone (ADH):
Controls reabsorption of water in the distal tubule of the kidney
Stimulates uterine contractions and milk ejection
What type of hormones (name TWO) are released from the anterior pituitary gland and what do they do?
Hormones which regulate other glands such as-
Thyroid stimulating hormone:
Stimulation of thyroid to produce thyroxin
Stimulates milk production
Which THREE hormones are released from the thyroid and what do they do?
Thyroxine T4, Triiodothyronine T3 and Calcitonin:
Metabolism, physical and mental growth
Which hormone is released from the parathyroid and what does it do?
Working with calcitonin, it maintains homeostasis of calcium and phosphate. Stimulates kidneys to produce calcitriol (active form of vitamin D)
What type of hormones (name THREE) are released from the adrenal cortex and what do they do?
Glucocorticoids eg. Cortisol:
Metabolism of glucose and carbohydrates
Mineralocorticoids eg. Aldosterone:
Water reabsorption in renal tubules
Gonadocorticoids eg. Oestrogen:
Changes during puberty and female sexual behaviour
Which TWO hormones are released from the adrenal medulla and what do they do?
Cardiovascular and Respiratory Function
Which hormone is released from the pineal and what does it do?
Light regulated secretion due to retinal connection. Feedback to hypothalmus inhibits Gonadotrophin releasing hormone. Influences sleep patterns, temperature and appetite
Which TWO hormones are released from the thymus and what do they do?
Thymopoetin and Thymosins:
Activation and differentiation of lymphocytes
Which FOUR hormones are released from the Pancreatic Islets of Langerhans and what do they do?
Conversion of glycogen to glucose
Conversion of glucose to glycogen
Inhibition of both glucagon and insulin
Release of pancreatic digestive enzymes
Which THREE hormones are released from the ovaries and what do they do?
Inhibits LH and FSH
Which hormone is released from the corpus luteum and what does it do?
Relaxation of pelvic ligaments
Which hormone is released from the blastocyst and what does it do?
Human Chorionic Gonadotrophin (hCG):
Maintains corpus luteum until placenta is fully formed
