This system is complicated in itself but broken down into its peripheral, somatic, autonomic, and central functions it becomes much simpler. One integral part of the nervous system is the peripheral nervous system. This structure is full of microscopic craniospinal nerves. These specific nerves are little tree like branches connected to and from the brain and spinal cord that carry impulses from the nervous systems muscles. There are two types of cells in this system including the sensory nervous cells and the motor nervous cells. Sensory cells are responsible for carrying information to the brain and motor cells are bound to importing the information found in the brain to the rest of the body.
