17
Q

The Pituitary Gland is connected to Hypothalamus by

A

Pituitary Stalk

18
Q

The anterior pituitary develops from

A

Branchial Arteries

19
Q

Which is the larger of the two pituitary lobes?

A

anterior

20
Q

Which of the two pituitary lobes is glandular and manufactures numerous hormones?

A

Anterior

21
Q

What is the function of posterior lobe of pituitary?

A

To release hormones after input from nervous system – releases neurohormones produced in hypothalamus

22
Q

The anterior pituitary stains what colour

A

Dark

23
Q

The posterior Pituitary stains

A

Pale

24
Q

The anterior pituitary has what type of cells

A

Acidophilic
Basophilic
Chromophobic

25
Q

Acidophilic cells stain

A

Pink

26
Q

Basophilic cells stain

A

Purple

27
Q

Features of Posterior Pituitary

A

It contains non-myelinated axons which are the neurosecretory cells. The cell bodies of these cells are located in the hypothalamus.

28
Q

The neurosecretory cells in pos pituitary secretes

A

Anti-Diuretic Hormone and Oxytocin

29
Q

Acidophils are what type of class

A

Somatotrophs and Mammotrophs

30
Q

Somatotrophs secrete

A

Somatotrophin aka Growth Hormone

31
Q

Somatotrophs target

A

Liver

Adipose

32
Q

Mammotrophs secrete

A

Prolactin

33
Q

Mammotrophs target

A

Mamillary Bodies

34
Q

Corticotrophs secrete

A

ACTH and MSH

35
Q

Corticotrophs target

A

Adrenal Cortex and Melanocytes of Skin

36
Q

Gonadotrophs secrete

A

FSH and LH

37
Q

Gonadotrophs target

A

Ovaries and Testes

38
Q

Pituitary Gland blood supply

A

Internal Carotid Artery branches Sup Hypophysical Artery and Inferior Hypophyseal Arteries

39
Q

How does the hypothalamus communicate with the anterior pituitary?

A

Through releasing/inhibiting of hormones into Hypothalmo-Hypophysial Portal System

40
Q

How does the hypothalamus communicate with the posterior pituitary?

A

Through neurosecretory cells via infundibulum

41
Q

Venous drainage of pituitary gland

A

is through hypophysial veins into the cavernous sinus.
