Detailed explanation-1: -Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord), whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body.
Detailed explanation-2: -Afferent neurons in the dorsal roots carry impulses from the body’s sensory receptors to the spinal cord, where the information begins to be processed.
Detailed explanation-3: -function. A sensory neuron transmits impulses from a receptor, such as those in the eye or ear, to a more central location in the nervous system, such as the spinal cord or brain.
Detailed explanation-4: -Billions of neurons work together to create a communication network. Different neurons have different jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body to allow muscles to move.
Detailed explanation-5: -Sensations begin as signals generated by touch receptors in your skin. They travel along sensory nerves made up of bundled fibers that connect to neurons in the spinal cord. Then signals move to the thalamus, which relays information to the rest of the brain.
