Question

Quizplus · Accepted Answer

The neuromuscular junction is the junction between a motor neuron and a skeletal muscle fiber, and it transmits an action potential between the nerve cell and muscle cell on a one-to-one basis. Therefore, both option (a) and (b) are true. The neuromuscular junction can produce either an excitatory postsynaptic potential (EPSP) or an inhibitory postsynaptic potential (IPSP) on the motor end plate, which is option (c). Hence, the correct answer is D.
