The sites where nerve impulse is transmitted from the nerve endings to the skeletal muscle cell membranes are the?
Correct answer: D. Neuromuscular junctions
- A. Z discs
- B. Dendrites
- C. Sarcomeres
- D. Neuromuscular junctions
Explanation
The neuromuscular junction is a highly specialised synapse between a motor neuron nerve terminal and its muscle fiber that is responsible for converting electrical impulses generated by the motor neuron into electrical activity in the muscle fibres.

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.
