Cranial nerves

testing of cranial nerve function is an important part of a neurological assessment (Department of Health Sciences, 2014). The brain has twelve main pairs of nerves, called cranial nerves. During a complete neurological assessment, most of the cranial nerves are evaluated to help determine the proper functioning of the brain (Neurological Examination, 2014). Each cranial nerve is paired and is present in each side of the brain. Cranial nerve I (Olfactory) is the sensory nerve of smell. Cranial nerve II (Optic) is the sensory nerve that carries vision to the brain. Cranial nerve III (Oculomotor) is responsible for pupil size and certain movements of the eye. Cranial nerve IV (Trochlear) is also related to movement of the eyes.…

Cranial Nerves [Your Name] [Mentor’s Name] [Course Code and Course Name] [The date] Cranial Nerves Introduction The cranial nerves are important nerves in our brain and they are located on the bottom surface of human brain. They are twelve pairs of nerves. Some of the cranial nerves are responsible to control body muscles, some of the cranial nerves are associated with the internal organs or glands such as human heart of lungs and some of the cranial nerves are responsible to take…

7 cranial nerve pairs out of 12 pairs in human nervous system function more or less in speech or hearing; these are the cranial nerves V (Trigeminal), VII (Facial), VIII (Vestibulocochlear), IX (Glossopharyngeal), X (Vagus), XI (Spinal Accessory), and XII (Hypoglossal). These have particular roles other than assisting speech or hearing. Furthermore, most clinical tests for cranial nerve functions neither are recommended to be performed by speech and hearing pathologists, nor are they related to…

The cranial nerves are made up of twelve categories with different functions. These categories are numbered with Roman numerals. The first cranial nerve is the Olfactory nerve which is involved in the sense of smell. The function of sense of smell works when the receptors in the epithelium of inside the nose sends signals to the brain (World of anatomy and physiology, 2007). The second cranial nerve is the optic nerve which is involved with the ability to see. The third cranial nerve is the…

THE SEVENTH CRANIAL NERVE Testing the Function of the Facial Nerve VII Anatomy & Physiology 203 November 15, 2014 Introduction: The facial nerve is the seventh cranial nerve of the peripheral nervous system that is the chief motor nerve of the face. It exits the brainstem between the pons and the medulla. The primary motor function is the control of the muscles of facial expressions and conveys impulses of taste sensations from the anterior two-thirds of the tongue and…

debilitating condition characterized by unilateral stabbing facial pain along the divisions of cranial nerve V. The lifetime prevalence of TN is estimated to be 0.7 per 1,000 people and usually presents between the fourth and seventh decades(1, 2). First line management involves medical therapy, although 10-25% of patients fail to respond to standard medication regimens and some patients may become resistant to medical treatment over time(3, 4). For patients with medically refractory TN, there…

I. Introduction: The purpose of the case study is to determine which of the patient’s cranial nerve(s) are damaged. The human brain and brain stem contain eleven pairs of cranial nerves to the neck and head, and one pair of cranial nerves to the abdomen and thorax. Each cranial nerve is numbered by a Roman numeral and in sequential order from cranial to caudal: (I) olfactory nerve carries sensory information to the brain and is responsible for the nose; (II) optic nerve carries sensory…

Discussion: To assess cranial nerve damage, the patient goes through a series of tests as listed: (1) follow a penlight right, left, up, down and towards the nose, (2) acuity and peripheral eye exam, (3) identify the smell of vanilla extract with eyes closed, (4) gag reflex, (5) clench jaw, (6) identify a warm probe placed on the forehead, left and right cheeks and chin, (7) taste, (8) walk across the room, (9) face symmetry, (10) Weber test. No abnormalities were found in tests one through six,…

Mathematically Modelling Clinical Resolutions of CSF pressure in Type-I Chiari Malformation and Syringomyelia Patients. Alexander S. Iacobucci, Andrew A. Hassall, Meagan E. Harrington, Korey V. Scanlin Introduction: Type-I Chiari Malformation is a neurological disorder describing the herniation of the cerebellum past the foramen magnum, occasionally resulting in a condition known as Syringomyelia. This disorder causes cysts, known as syrinxes, to form in the spinal cord and result in severe…

Aria's cranial Nerve Case Study Professor: Sandra Clabough Pragya Devkota Khanal 11/17/2017 Introduction: This study examined Aria, a 30-year-old woman who was recently brought in the emergency room after a bicycle accident. Apart from her external physical injuries, it is assumed that she may have internal head injuries due to the visible fracture of her temporal bone. In addition, the following symptoms were observed: a. Dizziness and difficulty in balancing her body. b. Unable to…
