Document Summary
Neural control of the larynx & respiration and cranial bones. Before we can understand neural control of the larynx we need to discuss the cranial nerves. The cranial nerves relay information between the brain and different parts of the body. They emerge from the brain, primarily from the part of the brain called the brainstem. Sensory, motor and mixed (sensory & motor. Motor: send impulses from brain to body. I = most anterior, vii = most posterior. Oculomotor 4 of the 6 extrinsic eye muscles. Trigeminal sensory fibers to the face and motor fibers to the chewing muscles. Abducens controls eye muscles that turn the eye laterally. S = sensory function, m = motor function, b = both (sensory and motor. Starting point for most of the cranial nerves (10 of the 12) Includes the medulla oblongata, pons, and midbrain. Provides the main motor and sensory innervation to the face and neck.
