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

piriformis muscle and the pelvis fascia and nerves coming from this plexus converge toward the lower part of the greater sciatic foramen and unite to form a flattened band‚ which continues primarily as the sciatic nerve. All nerves that root from the plexus either have anterior or posterior divisions and the posterior division has less nerves than the anterior. The posterior division contains the superior gluteal nerve (L4-S1)‚ inferior gluteal nerve (L5-S2) and the nerve to piriformis (S1‚ S2). The anterior

system is made up of all of the nerves and the wiring. This system sends the messages from the brain to the rest of the body. The brain keeps the body in order. It helps to control all of the body systems and organs‚ keeping them working like they should. The brain also allows us to think‚ feel‚ remember and imagine. In general‚ the brain is what makes us behave as human beings. The brain communicates with the rest of the body through the spinal cord and the nerves. They tell the brain what is

brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS is made up of nerves that branch out from the spinal cord
