SPINAL CORD, SPINAL NERVES, EYE AND EAR ANATOMY
2
Learning Objectives Identify structures of the spinal cord, both gross anatomical structures and cross sectional structures. Identify meninges and spaces around the spinal cord. Identify major peripheral nerves and nerve plexuses. Identify the accessory and internal structures of the eye, and explain their function. Describe the structures of the external and middle ear and explain how they function.

Nerve Plexuses All ventral rami except T 2 -T 12 form interlacing nerve networks called plexuses Plexuses are found in the cervical, brachial, lumbar, and sacral regions Each resulting branch of a plexus contains fibers from several spinal nerves
