WEEK 12,13: Biomechanics of Peripheral Nerves and Spinal Nerve Roots

Nervous system It senses changes in the body and in the external environment: It interprets these changes, Responds to this interpretation by initiating action in the form of muscle contraction or gland secretion. A stretching injury may result in failure of the nerve without failure of the surrounding membranes. If this occurs than the nerve has altered symptoms during its regeneration. Nerve regeneration is much more difficult if the entire nerve is damaged. Compression of a nerve can induce symptoms such as numbness, pain, and muscle weakness
