Q

Role of norepinephrine and acetylcholine in the sympathetic and parasympathetic nervous systems.

A

Parasympathetic: Acetylcholine is responsible for most of the transmissions.
Sympathetic: acetylcholine transmits until the final nerve to target organ; here is conveyed by norepinephrine most of the time.

Q

Give the basic schematic for the arteries from iliac artery to popliteal

A

common iliac artery splits off into internal and external iliac arteries. Internal iliac then feeds the superior and inferior gluteal arteries. The external iliac then becomes the femoral artery. On the superior part of the femoral artery, a branch goes deep (profunda). It then becomes the popliteal artery as it moves posterior at the lower part of the femur.

72
Q

Give the schematic for arteries below the knee

A

the popliteal artery has a branch that moves to the front: anterior tibial artery. Then the posterior two are: posterior tibial artery (lateral) and fibular artery (medial)

73
