What is the Nervous system ?
The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body
What is the Central Nervous system?
the complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord.
encased and protected by bone and membranes.
What is the Peripheral Nervous system ?
the nervous system outside the brain and spinal cord.
The peripheral nervous system is made up of nerves, which consist of bundles of axons (which are also called fibers).
nerves outside of the CNS.
not protected as extensively and is a route into the CNS.
What is the Somatic nervous system ?
the somatic nervous system is responsible for movement of voluntary muscles and the process known as a reflex arc.
This system carries nerve impulses back and forth between the central nervous system, which is the brain and the spinal cord, and the skeletal muscles, skin, and sensory organs.
is the system that helps the body adjust to the external environment through the voluntary movement of the skeletal system. Some examples of the somatic nervous system include: the blinking reflex, knee jerk reflex, gag reflex, and the startle reflex and rooting reflex in infants.
