This nerve has access to the cerebral cortex, but does not pass through the thalamus like other cranial nerves. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 2. function primarily motor nerves supply somatic motor fibers to carry proprioceptor fibers from 0 one of the extrinsic eye muscles the superior oblique muscles. Choose from 500 different sets of nerve functions flashcards on Quizlet. The olfactory nerveis involved in the sense of smell. The olfactory nerve is the shortest nerve in the body and it does not enter the brain stem. Provides sensory nerves for the anterior 2/3 of the tongue and motor innervation to the face muscles. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts. Spinal nerves can be impacted by a variety of medical problems, resulting in pain, weakness, or decreased sensation. As the sciatic nerve runs down the leg, it divides into a number of smaller branches along the way. Start studying Cranial Nerve Location and Functions. Number: 1 Type: Sensory Function: Sense of … Each of the 12 cranial nerves has a specific function that helps the brain control the actions of the body. Many of its branches provide nerve stimulation to the muscles in the legs. Sensory nerves throughout the leg and foot travel up the leg to merge with the sciatic nerve. The messages are converted from electrical to chemical and then back to electrical. Cranial Nerve Functions Quizlet is the easiest way to study, practice and master what you’re learning. These impulses travel from one neuron to another by crossing a synapse. The sciatic nerve is a peripheral nerve. They are named for their function or structure; for example, the trigeminal nerve consists of three primary branches, while the vestibulocochlear nerve serves the organs of equilibrium and hearing. A nerve provides a structured pathway that supports neuron function. Its nerve roots emerge from the lower spine and combine to form the sciatic nerve.
