Afferent nerve
Afferent Nerve
Afferent Nerve (/əˈfɛrənt/; from Latin afferens, meaning "bringing in"), is a type of nerve that carries sensory information from the body's periphery towards the Central Nervous System (CNS).
Etymology
The term "Afferent" is derived from Latin afferens, from ad- (to) + ferre (to bring). The term "nerve" comes from the Latin nervus, meaning "sinew, tendon, nerve".
Function
Afferent nerves are responsible for transmitting signals from sensory receptors towards the CNS. These signals can be related to touch, temperature, pain, or body position (proprioception). The information is then processed by the CNS to initiate an appropriate response.
