Detailed explanation-1: -An interneuron is a neuron that carries nerve impulses from one neuron to another. A motor neuron sends an impulse to a muscle or gland, and the muscle or gland then reacts in response. Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon.
Detailed explanation-2: -This change in electrical charge that occurs in a neuron when a nerve impulse is transmitted is known as the action potential. Once the action potential occurs, the number of positive ions exceeds the number of negative ions in this segment, and the segment temporarily becomes positively charged.
Detailed explanation-3: -The neuron which carries nerve impulses from receptors to spinal cord is called sensory neuron.
