1
Q

What is “placenta brain”?

A

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
Q

Name the TEN major components of the female endocrine system

A
Hypothalmus
Pineal Gland
Pituitary Gland
Thyroid and Parathyroid Glands
Thymus
Breasts
Adrenal Glands
Pancreatic Islets of Langerhans
Ovaries
Adipose Tissue
3
Q

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

A

Gonadotrophin-releasing hormone:

Stimulates release of luteinising hormone and follicle stimulating hormone

4
Q

Which TWO hormones are released from the posterior pituitary gland and what do they do?

A

Anti-diuretic hormone (ADH):
Controls reabsorption of water in the distal tubule of the kidney

Oxytocin:
Stimulates uterine contractions and milk ejection

5
Q

What type of hormones (name TWO) are released from the anterior pituitary gland and what do they do?

A

Hormones which regulate other glands such as-

Thyroid stimulating hormone:
Stimulation of thyroid to produce thyroxin

Prolactin:
Stimulates milk production

6
Q

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

A

Thyroxine T4, Triiodothyronine T3 and Calcitonin:

Metabolism, physical and mental growth

7
Q

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

A

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

8
Q

What type of hormones (name THREE) are released from the adrenal cortex and what do they do?

A

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
Q

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

A

Increase in:
Metabolism
Muscular contraction
Cardiovascular and Respiratory Function

Decrease digestion

10
Q

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

A

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

11
Q

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

A

Thymopoetin and Thymosins:

Activation and differentiation of lymphocytes

12
Q

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

A

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
Q

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

A

Oestrogen:
Reproductive cycle

Progesterone:
Reproductive cycle

Inhibin:
Inhibits LH and FSH

14
Q

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

A

Relaxin:

Relaxation of pelvic ligaments

15
Q

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

A

Human Chorionic Gonadotrophin (hCG):

Maintains corpus luteum until placenta is fully formed

16
Q

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

A

All maintain corpus luteum until placenta is fully formed

Oestrogen
Progesterone
Human Placental Lactogen
Corticosteroids
ACTH
TSH
