Match the following:
-Electrical current that travels the length of the sarcolemma that results in the contraction of the muscle fiber
A)sodium ions
B)acetylcholinesterase
C)acetylcholine
D)synaptic cleft
E)calcium ions
F)action potential

Question

Quizplus · Accepted Answer

The action potential is the electrical current that travels the length of the sarcolemma and results in the contraction of the muscle fiber.

Answer: C
 Acetylcholine is the neurotransmitter that is released into the synaptic cleft and binds to receptors on the sarcolemma, initiating the propagation of an action potential.

Answer: E
 Calcium ions play a crucial role in the contraction of muscle fibers by binding to troponin, which allows for the movement of the myosin head to pull actin filaments together.
