When we touch the hot body, sensory nerves present in the receptor (skin) receive impulses from receptor and carries to the spinal cord. The messages from the spinal cord are carried by the motor nerves to the effective organs (muscles) for the required response and we immediately remove our hands from hot body.
The neuron is the basic working unit of the brain, a specialized cell designed to transmit information to other nerve cells, muscle, or gland cells. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites.
A motor nerve is a nerve located in the central nervous system (CNS), usually the spinal cord, that sends motor signals from the CNS to the muscles of the body. This is different from the motor neuron, which includes a cell body and branching of dendrites, while the nerve is made up of a bundle of axons.
A sensory nerve, also called an afferent nerve, is a nerve that carries sensory information toward the central nervous system (CNS) and all those nerves which can sense or recognize the stimuli (Internal or External) are known as sensory nerves.
