Question

Select the term that best defines a neuron sending impulses toward the CNS.

a) Afferent neuron
b) Stupor
c) Parasympathetic
d) Mentation

Answer 1

An afferent neuron carries nerve impulses toward the central nervous system. They are also known as sensory neurons and convert various physical stimuli into nerve impulses.

Step-by-step explanation:

The term that best defines a neuron sending impulses toward the CNS (central nervous system) is afferent neuron. These neurons are specifically designed to carry nerve impulses from sensory receptors in various tissues and organs of the body to the CNS. Sensory (also called afferent) neurons convert physical stimuli like touch, light, and sound into nerve impulses, which then travel along the neurons' axons to reach the brain or spinal cord for processing. An easy mnemonic to remember this is 'afferent arrives' and efferent exits; afferent neurons bring signals into the CNS, and efferent neurons take commands out of the CNS to the rest of the body.
