🔴 Mechanism of Action 🔴
🔺Anterior Pituitary Hormones:-
1. Growth Hormone.... Acts on cell surface JAK-STAT receptors practically present on all type of cells (detail information is included in our general pharmacology notes has already uploded ) ...promotes growth of bones and all other organs by including hyperplasia.
(Growth of eye and brain is independent of Growth Hormone)
GH also maintain positive Nitrogen Balance.
Uptake of glucose by muscles is reduced while output from liver is increase and blood glucose level tend to rise.
2.Prolactin:-
Acts on JACK-STAT receptors on surface of target cells.
It promotes proliferation of ductal as well as acinar cells in the brest and induces synthesis of milk proteins and lactose.
Gonadotropins ( FSH & LH) also secreted from the anterior pituitary gland but, we will discuss in detail about that in steroidal section)
Note:-... You have to study some basics related with Hormones and secretion of hormones from particular gland before going to study mechanism of action of Hormone)
