Nerves:
The nerves are bundles of axons in the peripheral nervous system that act as information highways to carry signals between the brain and spinal cord and the rest of the body. There are many different nerves in the body here are some: afferent, efferent, and mixed nerves. Some of the nerves in the body are specialized for carrying information in only one direction. Afferent nerves are nerves that carry information from sensory receptors to the central nervous system. Efferent nerves carry signals only from the central nervous system to effectors such as muscles and glands. Another important nerve is the cranial nerves they extend from the inferior side of the brain are 12 pairs of cranial nerves. This provides a direct connection to the brain for the special sense organs, muscles of the head, neck, and shoulders, the heart, and the GI tract. The last nerve is the spinal nerves; they extend from the left and right sides of the spinal cord are 31 pairs of spinal nerves. The spinal nerves are mixed nerves that carry both sensory and motor signals between the spinal cord and specific regions of the body.
