Question

At a myoneural junction, what is the function of the motor end plate?

To release neurotransmitters that travel toward the axon terminal
To bind neurotransmitters and generate an action potential in the sarcolemma
To release sodium and potassium that travel toward the axon terminal
To bind sodium and potassium and generate an action potential in the sarcolemma

Answer 1

To release neurotransmitters that travel toward the axon terminal

Answer 2

Correct answer: B). To bind neurotransmitters and generate an action potential in the sarcolemma

The motor end plate is the area, which is found between the motor neuron and the muscle fiber. It has acetylcholine receptors that are known to bind with the neurotransmitter acetylcholine. It is released at the neurotransmitter junction, which is known to stimulate the skeletal muscles to contract and generate an action potential in the sarcolemma of muscles.

Hence, the correct answer would be option B.
