The synapse formed at the sites where the terminal branches of the axon of a motor neuron conduct to a target muscle cell is called:
Correct answer: C. Motor end plate
- A. Sensory end plate
- B. Synapse end plate
- C. Motor end plate
- D. Postsynaptic membrane
Explanation
The motor end plate is the specialized area at the neuromuscular junction where the axon terminal of a motor neuron forms a synapse with a muscle fiber. It is responsible for transmitting neural signals to muscle cells, resulting in muscle contraction. The term sensory end plate is associated with sensory neurons, not motor neurons. Synapse end plate is not a recognized term in neuroscience. The postsynaptic membrane refers generically to the membrane receiving neurotransmitters at any synapse, not specifically at neuromuscular junctions.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
