The peripheral nervous system is a collection of peripheral nerves‚ ganglia and specialized sensory structures that‚ as a unit‚ carries sensory and motor information between all organs and body system. The peripheral nervous system is divided into two major parts‚ somatic and autonomic nervous system. The somatic nervous system is made up of nerves that connects

joint. The tight space between this fibrous band and the wrist bone is called the carpal tunnel. The median nerve passes through the carpal tunnel to receive sensations from the thumb‚ index‚ and middle fingers of the hand. Any condition that causes swelling or a change in position of the tissue within the carpal tunnel can squeeze and irritate the median nerve. Irritation of the median nerve in this manner causes tingling and numbness of the thumb‚ index‚ and the middle fingers -- a condition known

The homeostatic capability of the body involves an internal balance in order for the body to properly function. This system is known as dual innervations. These are innervations affected by two systems known as the parasympathetic and sympathetic nerve systems. The effector organs for the sympathetic system include: the smooth muscle of blood vessels‚ lungs‚ viscera‚ scalp‚ pupils‚ the heart‚ and glands. The effector organs for the parasympathetic system include: lacrimal glands‚ salivary glands

The PNS can be regenerate and it will regrow. The brain and spinal cord are the main parts of the nervous system. The brain controls every part of your body and is located top of our head inside our skull. The spinal cord with controls our movement. Nerve cells contain 3 parts: dendrites‚ cell body and the axon.
