How are neurons classified on the basis of their functions?
Call
Neurons are classified into three types based on their functions:
1. Afferent neuron (Sensory neuron):
Function: It carries impulses from sense organ to the central nervous system (CNS).
Location: It is found in the dorsal root of the spinal cord.
2. Efferent Neuron (Motor neuron):
Function: It carries impulses from CNS to effector organs.
Location: It is found in the ventral root of the spinal cord.
3. Interneuron or association neuron:
Function: They perfonn processing, integration of sensory impulses and activate appropriate motor neuron to generate motor impulse.
Location: These are located between sensory and motor neurons.
