16
Q

What is the role of ADH?

A

prevents the formation of large volumes of urine and hence helps the body to save water. Causes a portion of each tubule in the kidney to reabsorb water from urine

17
Q

Oxytocin’s role in child birth

A

Contracting of muscles in the uterine wall and milk let down by forcing milk into ducts from milk glands

18
Q

Pineal gland shape

A

Pine nut shaped

19
Q

Location of pineal gland

A

Dorsal aspect of the brain’s diencephalon region

20
Q

Why is the pineal gland a member of the nervous system?

A

It receives visual stimuli

21
Q

What does the pineal gland secrete?

A

Melatonin - sleep

22
Q

What is the structure of the thyroid gland

A

Made up of two large lateral lobes and a narrow connecting isthmus

23
Q

What extends upward from the isthmus?

A

Pyramidal lobe

24
Q

What is the weight of the thyroid gland in adults?

A

30 g

25
Q

What is in the thyroid gland?

A

Follicles with hormone storing colloid

26
Q

Role of calcitonin

A

Decrease blood Ca 2+

27
Q

What kind of glands are in the posterior surface of the gland

A

4 or 5 parathyroid glands

28
Q

What is a antagonist to calcitonin and what does it act on

29
Q

Where are adrenal glands located?

A

On top of the kidneys

30
Q

Two portions of adrenal gland
