33
Q

What is hyperopia

A

Farsightedness

-Converges behind the retina

34
Q

How to correct hyperopia

A

Use converging lens to focus it closer and onto the retina

55
Q

Function of CCK

A

aid a series of processes involved in digestion
- stimulating pancreatic acinar cells to release digestive enzymes,
stimulating feelings of satiety (fullness) to suppress hunger, inhibiting stomach emptying, lowering gastric acid secretion.

62
Q

Stages of an action potential

A
  1. Cell crosses threshold voltage and is depolarized when sufficient amounts of Na+ enter cell
  2. Repolarization occurs as K+ cells leave the cell
  3. Refractory period occurs where K+ diffuses back into cells and cell reaches returns to potential
