Nerves
Nerves carry motor commands out to muscle and return sensory information from the skin, joints, and deeper tissues. The peripheral nerves of the limbs arise from plexuses formed by spinal nerve roots, while the twelve cranial nerves arise directly from the brain and brainstem.
Every nerve in the AnatoMemory reference is listed below, grouped by body region. Each card covers the roots, course, motor and sensory territory, and the injury patterns exams test most often.
