PPT-Ventricles, Spinal Cord & Cranial Nerves

Objectives Identify cranial nerves and describe the function of each Understand the signs and tests for CN dysfunction Make an accurate model of the ventricle system of the brain Discuss the clinical implications of dysfunction in the ventricular system.

HONORS ANATOMY & PHYSIOLOGY. Spinal Cord. w/spinal nerves contain neural circuits that mediate some of your most rapid reactions to environmental changes. Protective Structures. 2 types of CT coverings surround & protect delicate nervous tissue. Spinal Cord. Location. Begins at the foramen magnum . Ends as conus medullaris at L. 1. vertebra. Functions. Provides two-way communication to and from the brain. Contains spinal reflex centers.
