Detailed explanation-1: -You have two main types of nerves: Sensory nerves carry signals to your brain to help you touch, taste, smell and see. Motor nerves carry signals to your muscles or glands to help you move and function.
Detailed explanation-2: -Nerve fibers of the PNS are classified according to their involvement in motor or sensory, somatic or visceral pathways. Mixed nerves contain both motor and sensory fibers. Sensory nerves contain mostly sensory fibers; they are less common and include the optic and olfactory nerves. Motor nerves contain motor fibers.
Detailed explanation-3: -Nerves In the Peripheral Nervous System Sensory: Connects the brain and spinal cord to your skin and allow you to feel pain and other sensations. Autonomic: Controls involuntary function (e.g., blood pressure, digestion, heart rate). Motor: Connects the brain and spinal cord to muscles to stimulate movement.
Detailed explanation-4: -The spinal nerves carry both sensory and motor messages and are called “mixed nerves.” Among the cranial nerves are five pairs of motor nerves, three pairs of sensory nerves, and four pairs of mixed nerves.
