Morphology

afferent + nerve

The adjective 'afferent' means conducting sensory information inward, and when combined with 'nerve' it straightforwardly denotes a nerve that carries impulses toward the central nervous system. This is a regular adjective + noun composition used in technical discourse, so a learner who knows both constituents can directly infer the MWE's meaning.

Etymology

Afferent nerve comes from afferent (meaning 'to bring to') and nerve, so picture a road that carries messages from the body's senses to the brain or spinal cord. That's why an afferent nerve means a nerve that 'brings' sensory signals 'toward' the brain or spinal cord.
