Cranial Nerves

In this research paper I will treat the 12 cranial founts of the central nervous system, and observe their belongs and locations. Cranial substances are twelve pairs of administrations that bulge from the nervous tissue of the brain. Some of these nerves bring reading from sensory variety meat to the brain, other nerves control muscles, and the stay nerves are connected to glands or internal organs such as, your lungs and heart.

The Olfactory nerve, Nervus Olfactorius, is the first of the twelve cranial nerves. The olfactory nerve is the shortest of the twelve cranial nerves and 1 of 2 that do not join with the brainstem. This nerve is liable for your sense of smell. It is located in the olfactory mucosa of the fastness parts of the nasal cavity. The sense of smell is stimulated by olfactory receptors activated by gas molecules, which enter the nestle through respiration. This electrical activity is sent to the olfactory medulla oblongata and then sent to the central nervous system for appropriate smell by the way of the olfactory tract. There is a means to test for proper functioning of this nerve. A mendelevium will block one of your nostrils and hold something of a unbendable odor under the open nostril. The test would obviously be repeated for the remaining nostril.




The second cranial nerve, the optic nerve is the nerve that connects the meat to the brain. It is a collection of thousands of nerve fibers that manoeuvre visual images from the eye to the brain. To test for visual activity function the patient is asked to read letters from a chart, a Snellen chart, of contrasting sized letters. Damage to this nerve may cause imperishable vision loss.
Nervus Oculomotorius, Latin for the third cranial nerve Occulomotor Nerve. This nerve enters the eyes socket through the superior orbital fissure. The Occulomotor nerve is a motor nerve that sends fibers to muscles of the eye to control eye movement. This nerve is responsible for moving the eyeball, keeping the eyelids open and maintaining...If you desire to get a full essay, order it on our website: Orderessay
