Question

What is the nerve cell that conveys impulses from the central nervous system to the muscles?

A.

Celia

B.

Afferent neuron

C.

Dendrite

D.

Efferent neuron

Correct option is D


Ans (d)
Sol. Explanation:
· Efferent neurons (also known as motor neurons) carry impulses from the central nervous system (CNS) to the muscles and glands. They are responsible for motor functions, such as muscle contraction.
· Afferent neurons (sensory neurons) carry impulses from sensory receptors (like the skin or eyes) to the CNS, allowing the brain to receive information from the body.
· Dendrites are part of a neuron that receive incoming signals from other neurons, but they do not convey impulses to muscles.
· Celia seems to be a typo and does not relate to a type of neuron; cilia are hair-like structures on cells that help with movement and sensory functions but are not related to neural impulse transmission.
