A motor neuron:
Correct answer: C. Carries impulse from CNS to muscles
- A. Carries impulse from effectors to CNS
- B. Carries impulse from receptors to CNS
- C. Carries impulse from CNS to muscles
- D. Connects sensory nerves to ganglions
Explanation
Efferent neurons (or motor neurons) carry impulses from the central nervous system (CNS) to muscles and glands. These impulses initiate muscle contraction or glandular secretion, enabling responses such as movement or other actions in the body based on CNS signals.

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.
