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.…

Purpose- To identify the functions of the cranial nerves of the peripheral nervous system such as the olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory, and the hypoglossal nerves. I will examine these functions with a series of behavior tests on my partner to see if they are functioning properly and if they are not then this will be considered an identified dysfunction of a cranial nerve which is a diagnosis. Materials…

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…

The cranial nerve examination involves the number of tests, each designed to determine if any of the nerves are malfunctioning. The olfactory nerve is tested by offering a vanilla extract, for the patient to smell and identify through both right and left nostril. The optic nerve is tested by using a Snellen chart, with and without glasses or contact lenses, if applicable, and by checking the patients peripheral vision with a pencil on both right and the left side. The oculomotor and trochlear…

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…

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…

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…

Craniosynostosis or premature fusion of one or more cranial sutures in infants disturbs normal brain growth. This condition causes abnormal skull configuration, increased intracranial pressure, headache, strabismus, blurred vision, blindness, psychomotor retardation. The diagnosis of craniosynostosis is very simple. Pediatricians should routinely assess neurological status and measure head circumference and anterior fontanelle. When necessary, ultrasound of CNS, X-ray and cranial CT scan can be…
