The Brain and Cranial Nerves One of the most complex and fascinating things in the human body is the brain. The body is “capable of almost everything, but it would not be possible, without the brain receiving information, and analyzing the information.” The brain is aware of its surroundings, via input from the spinal cord and cranial nerves. Cranial nerves with sensory functions allow us to smell and see. Nerves with both motor and sensory functions are responsible for everything from tasting
identify the functions of the cranial nerve 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 who is Jazmine Cooley to see if all nerves are functioning properly and if they are not, then this will be considered an identified dysfunction of a cranial nerve which is a diagnosis.
purpose was to test all of the cranial nerves to develop a better understanding of where they are located, what actions they possess, and how they carry out those actions into one’s daily life. There are 12 pairs of cranial nerves located in the human body. The first two pairs are attached and associated with the forebrain while the other ten pairs with the brain stem. Cranial nerves are exceedingly important when serving the head and neck along with cranial nerve X (Vagus) which assists in carrying
Cranial Nerves The cranial nerves are consists of 12 intricate nerves and their functions control the entire body. The cranial nerves are divided into many important nerves such as; the olfactory, optic, oculomotor, trochlear, trigeminal, abducal, facial vestibulochlear, glossopharyngeal, and hypoglossal nerves, and each one are vital to the response of our entire body. Physical assessments are divided by areas in which each evaluation have an important significance in an accurate evaluation
The human body does amazing things on a daily basis. All the senses that the body uses consists of nerves, neurotransmitters and the brain decodes the messages that was received. Smell is the passing of odorants through the nose, received by the olfactory cells, and are sent directly to the brain. Taste is the weakest of the five senses but it is the sensory function of the central nervous system( The Science of Taste and Smell). We taste and smell things every day but little do most people know
The most severe limitation would be if the head drooped forward causing the inhibition of respiration. For a lesion here an SLP would typically work on correct posture to assist with the clients rehabilitation. Lastly damage to the XIIth nerve, the hypoglossal nerve, would affect the motor aspects of the intrinsic and extrinsic tongue muscles, causing deviation and/or atrophy. An SLP would typically work with tongue strengthening exercises or articulation treatments to help correct/treat damage to
characteristics of flaccid dysarthria generally reflect damage to cranial nerves with motor speech functions (e.g., cranial nerves IX, X, XI and XII) (Seikel, King & Drumright, 2010). Lower motor neurons connect the central nervous system to the muscle fibers; from the brainstem to the cranial nerves with motor function, or from the anterior horns of grey matter to the spinal nerves (Murdoch, 1998). If there are lesions to spinal nerves and the cranial nerves with motor speech functions, it is indicative of a lower

Neurofibromatosis (NF) is a genetic disorder of the nervous system. This can cause tumors to form on the nerves anywhere in the body at any time. Neurofibromatosis affects all races, all ethnic groups and both sexes equally. NF if one of the most common genetic disorders in the United States. NF has three genetically distinct forms are NF1, NF2 and Schwannomatosis
the neurological assessment as an important analytical tool that evaluates the functionality of an individual’s nervous system. Blumenfeld (2010) dissected and evaluated the neurological assessment into six functional components, mental status, cranial nerves, motor exam, reflexes, co-ordination and gait, and a sensory examination. The mental status exam investigates global and limbic brain functions, left and right parietal functionality and language. This is achieved through tests such as, level
Integumentary System- Hypertrichosis Hypertrichosis, which is also known as Ambras Syndrome or Werewolf Syndrome, is excess growth of hair on parts of the body. Hypertrichosis can either be generalized meaning it covers the whole body or localized meaning it is only on a certain area. There are three different hair types that may be involved. They include Lanugo (long and silky), Vellus (replace Lanugo after birth except on the scalp and eyebrows), and terminal (course, thick, and pigmented). Generalized
As a giant herbivore, the Diplodocus fed primarily on conifers, ginkgo leaves, ferns, and other soft leafy vegetation available at the time (Young et al., 2012). Additionally, there currently stand two main feeding theories when it comes to the Diplodocus. The Diplodocus, with shorter front legs, is often envisioned as being a low browser where it would keep its neck close to the ground and feed off the leafy ground vegetation as it would have been in a more comfortable posture for feeding. As popularized
I. A. Neurofibromatosis, or NF, is the most common neurological disorder caused by a single gene. B. Two types: NF1 and NF2 1. NF1- affects 1 out of 4,000 people 2. NF2- affects 1 out of 50,000 people C. Inherited and autosomal D. Can be potentially fatal E. The Elephant Man, Joseph Merrick, was thought to have NF, but he really had Proteus syndrome F. Neurofibromatosis is a unique disorder because it is incurable, can be severely disfiguring, and can be either benign or terminal. II. A. NF is
I am an Organ Donor As we stood over the precisely dissected bodies, trying to distinguish between the phrenic and vagus nerves, the greater and lesser omentums, and the left and right gastroepiploic arteries, I inadvertently looked away from my prosection and saw Stephanie (one of the TAs) walking across the room carrying a human head face down against her palm. This sight forced me to recognize a truth about these prosections; these body pieces, picked clean of fat and connective tissue, were
Introduction Bell’s palsy is the name given to a nerve disorder that results in unexpected paralysis of the face due to the facial nerve acting abnormally. Paralysis is commonly found only on one side of the face; however, it can occur on both sides. Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who first came across the condition. (NINDS Bell's Palsy, sec. 1). In this paper, the pathophysiology, which is a discussion of the mechanism behind Bell’s Palsy will be discussed

Just to review, without the facial nerves functioning properly, literally any movement involving eyes, forehead, and mouth (among other parts) will be hindered. In addition to memory problems there may be balance problems as well. I can personally attest to the fact that Bell’s Palsy makes
functions of the facial nerve in humans. The facial nerve is one of twelve cranial nerves that innervates the head and neck. These nerves serve a variety of functions, both sensory and motor, and are responsible for moving the muscles in the face, head and neck, and receiving information the brain can interpret into all five sense. Appendix A outlines each cranial nerve, it’s sensory and/or motor function, and the foramen in the bones of the skull it passes through. The facial nerve fibers originate
The body works in amazing ways like a fine tuned machine. All organ systems within the body depend on one another for survival in some way or form at all times. Cherif et al., (2010) state, the body depends on the precise action of each organ to maintain physical, mental, and emotional health of a human being. Also, homeostasis, the regulatory of body temperature plays a survival role in maintaining body functions. The integumentary system (skin) is the largest, and the most important part of
emeyer Period 3 Mrs.Coik Limb Paralysis Limb paralysis is the loss or impairment of movement of the limb as a result of muscle and nerve damage. The one of the most common causes of limb paralysis is a cerebral vascular accident, otherwise known as a CVA or stroke. The loss of movement can be localized and affect only a small area of muscle. It has the ability to affect a large area of muscle referred to as generalized paralysis. Another type of paralysis is unilateral paralysis, which is paralysis

lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system. The neuron has two important structures called the dendrite and axon, also called nerve fibers. The dendrites are like tentacles that sprout from the cell and the axon is one long extension
