The parts of motor and sensory nerves which branch from the brain and spinal cord.
Any nerve that connects the brain or spinal cord with peripheral receptors or effectors.
Spinal nerves are the nerves responsible for transmitting information to and from the spinal cord.
Nerves connecting the central nervous system (CNS, which includes the brain and spinal cord) to specific parts of the body are known as peripheral nerves. There are 12 pairs of cranial nerves and 31 pairs of spinal nerves. Some of these peripheral nerves are sensory, transmitting signals from sensory organs and nerve endings to the brain and spinal cord. In contrast, others are motor nerves, sending signals from the CNS to initiate actions in the body’s tissues.
Peripheral nerves link the central nervous system, comprising the brain and spinal cord, to the rest of the body. There are 12 pairs of cranial nerves and 31 pairs of spinal nerves. Some of these nerves are sensory, transmitting sensations from the body or external environment to the central nervous system. Others are motor nerves, sending signals from the central nervous system to muscles, prompting them to contract, or to glands, stimulating them. Most peripheral nerves have both sensory and motor elements.
