Question

Neurons are termed:

a. efferent if they conduct impulses toward the cell body
b. afferent if they conduct impulses toward the CNS
c. afferent if they conduct impulses away from the CNS
d. efferent if the conduct impulses toward the CNS

Answer 1

The correct answer will be option B.

Step-by-step explanation:

Neurons are the structural and functional unit of the nervous system. Based on the transmission of nerve impulse these neurons can be divided into two divisions :

1. Afferent neurons: Neurons which transmit the impulse from the periphery to CNS- brain or spinal cord. Sensory neurons are such neurons which carry the impulse of stimulus to CNS.

2. Efferent neurons: Neurons which transmit the signals from the CNS to the periphery or muscle which causes voluntary action. Motor neurons are considered efferent neurons.

Thus, option B is the correct answer.
