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

Answer is To bind neurotransmitters and generate an action potential in the sarcolemma.

The motor end plate is the area between the motor neuron and the muscle fibre. It contains acetylcholine receptors which binds neurotransmitter acetylcholine. This neurotransmitter is released at the neuromuscular junction which stimulates the skeletal muscles to contract to generate an action potential in sarcolemma of muscles.
