A

From an upwards projection of the pharynx

10
Q

A

From a downwards projection of the brain

11
Q

How is the anterior pituitary gland historically referred to as?

A

The master gland

12
Q

Why do they call the anterior pituitary gland the master gland?

A

Due to the critical functions of its hormones

13

Growth by stimulating liver and other tissues

18
Q

What hormone does GH produce?

A

Insulin like growth factor

- IGF-1

19
Q

What does IGF-1 do?

A

It accelerates the amino acid transport into cells

  • which increases protein synthesis
  • which increases growth (bone, muscle, tissue)
20
Q

What does IGF-1 stimulate?

A

Fat metabolism

- mobilizes stored lipids in adipose cells and speeds yo liquid metabolism after lipids have entered another cell

21
Q

How do IGF-1 get there energy?

A

Through gluconeogenesis

- lipid catabolism

22
