Nervous System

Introduction

What are the two types of cells found in the peripheral nervous system?

The peripheral nervous system consists of afferent or sensory neurons and efferent or motor neurons. The afferent nerve cells (from the Latin, ad, meaning “toward,” and ferre, meaning “to bring”) carry sensory information from the peripheral to the central nervous system. They have their cell bodies in ganglia and send a process into the central nervous system. The efferent nerve cells (from the Latin ex, meaning “away from,” and ferre, meaning “to bring”) carry information away from the central nervous system to the effectors (muscles and tissues). They have cell bodies in the central nervous system and send axons into the periphery.
