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

Question

Quizplus · Accepted Answer

The action potential is the electrical current that travels the length of the muscle fiber, causing it to contract.

Answer: D
 Sodium ions are involved in the depolarization of the muscle cell, which helps generate the action potential that travels the length of the muscle.

Answer: E
 Acetylcholinesterase is an enzyme that breaks down acetylcholine in the synaptic cleft, which allows for the muscle to relax after contraction.

Answer: B
 Acetylcholine is a neurotransmitter that is released from the motor neuron and binds to receptors on the muscle fiber, initiating the depolarization of the membrane and the generation of the action potential.

Answer: A
 Calcium ions are involved in the release of acetylcholine from the motor neuron and in the initiation of the contraction process within the muscle cell.

Answer: C
 The synaptic cleft is the small gap between the motor neuron and the muscle fiber, across which acetylcholine is released and binds to receptors on the muscle fiber.
