1

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

2

Name the TEN major components of the female endocrine system

Hypothalmus
Pineal Gland
Pituitary Gland
Thyroid and Parathyroid Glands
Thymus
Breasts
Adrenal Glands
Pancreatic Islets of Langerhans
Ovaries
Adipose Tissue

3

Which hormone is released from the hypothalmus and what does it do?

Gonadotrophin-releasing hormone:
Stimulates release of luteinising hormone and follicle stimulating hormone

4

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

Oxytocin:
Stimulates uterine contractions and milk ejection

5

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

Prolactin:
Stimulates milk production

6

Which THREE hormones are released from the thyroid and what do they do?

Thyroxine T4, Triiodothyronine T3 and Calcitonin:
Metabolism, physical and mental growth

7

Which hormone is released from the parathyroid and what does it do?

Parathyroid Hormone:
Working with calcitonin, it maintains homeostasis of calcium and phosphate. Stimulates kidneys to produce calcitriol (active form of vitamin D)

8

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

9

Which TWO hormones are released from the adrenal medulla and what do they do?

Increase in:
Metabolism
Muscular contraction
Cardiovascular and Respiratory Function

Decrease digestion

10

Which hormone is released from the pineal and what does it do?

Melatonin:
Light regulated secretion due to retinal connection. Feedback to hypothalmus inhibits Gonadotrophin releasing hormone. Influences sleep patterns, temperature and appetite

11

Which TWO hormones are released from the thymus and what do they do?

Thymopoetin and Thymosins:
Activation and differentiation of lymphocytes

12

Which FOUR hormones are released from the Pancreatic Islets of Langerhans and what do they do?

Glucagon:
Conversion of glycogen to glucose

Insulin:
Conversion of glucose to glycogen

GHRIH:
Inhibition of both glucagon and insulin

Pancreatic Polypeptide:
Release of pancreatic digestive enzymes

13

Which THREE hormones are released from the ovaries and what do they do?

Oestrogen:
Reproductive cycle

Progesterone:
Reproductive cycle

Inhibin:
Inhibits LH and FSH

14

Which hormone is released from the corpus luteum and what does it do?

Relaxin:
Relaxation of pelvic ligaments

15

Which hormone is released from the blastocyst and what does it do?

Human Chorionic Gonadotrophin (hCG):
Maintains corpus luteum until placenta is fully formed

16

Which SIX hormones are released from the placenta and what do they do?

All maintain corpus luteum until placenta is fully formed

Oestrogen
Progesterone
Human Placental Lactogen
Corticosteroids
ACTH
TSH
