Which category of neurons is responsible for transmitting signals from sensory organs to the brain?

Afferent neurons are primarily responsible for transmitting sensory information from sensory organs to the brain. These neurons carry signals related to senses such as touch, sight, sound, taste, and smell. The process begins when sensory receptors detect stimuli from the environment. Afferent neurons then relay this information through electrical impulses to the central nervous system (CNS), which includes the brain and spinal cord for processing and interpretation.

In contrast, efferent neurons carry signals away from the brain to various effectors, such as muscles and glands, to facilitate responses or actions. Interneurons serve as connectors or relays between afferent and efferent neurons within the CNS, playing a key role in reflex actions and complex signaling within the brain. Motor neurons, similar to efferent neurons, specifically control voluntary and involuntary muscle movements. Understanding the distinct functions of these neuron types clarifies the critical role afferent neurons play in sensory communication to the brain.
