Detailed explanation-1: -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-2: -Sensory neurons are the nerve cells that are activated by sensory input from the environment-for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.
Detailed explanation-3: -Sensory neurons are found in receptors such as the eyes, ears, tongue and skin, and carry nerve impulses to the spinal cord and brain. When these nerve impulses reach the brain, they are translated into ‘sensations’, such as vision, hearing, taste and touch.
