Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A nerve fiber that carries impulses toward the cell body is a/an?
A
dendrite
B
axon
C
neuron
D
myelin
Explanation: 

Detailed explanation-1: -Dendrites are the branched thread-like extensions of a neuron that carry impulses from nearby neurons to the cell body (cyton). Axons carry impulses away from the cyton.

Detailed explanation-2: -They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons. The number of dendrites on a neuron varies. They are called afferent processes because they transmit impulses to the neuron cell body.

Detailed explanation-3: -Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
