Question

What is an end-plate potential, can it trigger AP?

a)The initial depolarization of the muscle membrane; yes
b)The final repolarization of the nerve membrane; no
c)The initiation of action potential; yes
d)The termination of action potential; no

Answer 1

An end-plate potential is the initial depolarization of the muscle membrane. It can trigger an action potential in the muscle fiber, leading to muscle contraction.

Step-by-step explanation:

An end-plate potential is the initial depolarization of the muscle membrane. It is caused by the binding of acetylcholine to acetylcholine receptors on the muscle end-plate. This depolarization can trigger an action potential in the muscle fiber, leading to muscle contraction.

The correct answer to the question is: a) The initial depolarization of the muscle membrane; yes.
