Detailed explanation-1: -Sensory neurons form the afferent division of the PNS, and transmit impulses from sensory receptors in the skin or internal organs to the CNS.
Detailed explanation-2: -The function of sensory neurons is to detect and transmit signals from a peripheral region to a more central location in the central nervous system, i.e., the spinal cord or the brain. The transduction of the signal takes place in the sensory receptor at the dendritic end of the neuron.
Detailed explanation-3: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.
