The Peripheral Nervous System

We had Brad Haskell for lecture. We learned that the spinal cord ends at L2 region of the vertebral column. Plexuses are a weaving or braiding of a nerve and the nerves that come off from it. The principal plexuses are cervical, brachial, lumbar, and sacral plexuses. The sciatic nerve is the longest and thickest nerve in the body. Phrenic nerve controls the diaphragm injury to C5 can be life threatening. We reviewed the cranial nerve names and a few of he foramen. We went over the central canal of the spinal column.
This relates to every day living for any human being because if some reason there is an injury or the neurons misfire it effects the way our bodies work. The sensory nerves have to get the impulse to the brain in order for an impulse to be sent to the motor nerves for movement to happen.
