Afferent neurons, also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain. Sensory information may involve special senses, such as vision, hearing, smell, or taste, as well as the sense of touch, pain, and temperature.
A sensory neuron (sometimes referred to as an afferent neuron) is a nerve cell that detects and responds to external signals. Sensory neurons receive information via their receptors, which are part of the peripheral nervous system, and convert this information into electrical impulses.
Key Terms. efferent: Efferent neurons transmit signals from the central nervous system to the effector cells (e.g. motor neurons). afferent: Afferent neurons convey information from tissues and organs into the central nervous system (e.g. sensory neurons).
Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. [1] This process is called sensory transduction.
Afferent and efferent neurons are the two primary types of neurons that play distinct yet interconnected roles in this communication network. Afferent nerve fibers, also known as sensory neurons, carry signals from sensory receptors towards the central nervous system.
