Purpose- To 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.
Materials and Methods-
Gloves
Container full of substance
Standardized eye chart
Tape line
Tape
Flashlight
Cotton swab
Tuning fork
Tongue depressor
Ruler
Procedure- I did a series of behavior tests on my partner Jazmine Cooley
I also used a ruler to point at each letter as she read out loud what letter she can see. Then, when she was finished reading, she stopped at a particular line and I wrote down her results. I also tested her other eye which is her right eye which had different results. After, she finished and I wrote her results down, I tested her vision field by sitting in front of her and placing my finger near her ear and she then told me when she seen my finger at
She tried to read row 6 feet that was 1.8 millimeters but could not see the rest of the letters. Next, I tested her right eye, however she could not see the row that was 15 feet, which was 4.5 millimeters she also mess up on a letter in row 20 feet. But with her vision test it suggested that her visual field are functioning fine. I held up 3 fingers and then held up two and she identifies what she had seen in her vision fields which she identified
...ut a 7 years old girl which loss her ability to understand speech. She had a normal hearing and understood various environmental sounds. Her brain was computerized using axial tomography but the result was normal. But electroencephalogram showed wave activity from her left side of the temporal leads. She was diagnose as having verbal auditory agnosia. The treatment consisted of diazepam therapy. Diazepam therapy orally began with taking 2 mg diazepam every day. Diazepam is commonly used to treat anxiety,panic attacks,insomnia and some other medical issues. One year later, her impaired auditory was dramatically improved. The dichotic listening test revealed a left ear advantage for both environmental sounds and spoken words. The results seemed to suggest that in this patient the right hemisphere might be functioning as a speech center instead of the left one.

Other structures that are involved and were mainly effected in this assignment’s patient is the cervical lymph nodes. These lymph nodes are small, bean-shaped masses that allows the storage of lymphocytes, and filter the lymph fluid for pathogens and malignant cells (Marieb & Hoehn, 2007). Another structure in the nasopharynx are the cranial nerves. They control swallowing, vision, hearing, eye movement, and such would have to be given more attention when exploring
Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise be jerky muscle motions. The medulla controls the elementary functions responsible for life, such as breathing, cardiac rate and kidney functions. The medulla contains numerous of timing mechanisms as well as other interconnections that control swallowing and salivations.

So, Lauren becomes frustrated when overstimulated and has a low-threshold when addressed with auditory and vestibular, but is determined during therapy to master these
Based upon previous knowledge of brain function, what results from the testing were consistent with a brain injury?
The subject placed their hand, palm facing up, on the worktop and closed their eyes. The tester asked the subject to respond with “one” or “two” regarding the number of points they detected. The tester used the two-spot discriminator; progressively moving the two parts further apart to gauge the receptor sensitivity and recorded when the subject said, “two.” The test was replicated triplicate and then moved to the back of the neck, the upper arm and the palm. After completion the tester and subjects switched places and repeated the exercise
Marie Jean Philip was born on April 20, 1953, in Worchester, Massachusetts. She was the first-born child. Although she was born to deaf parents, Marie’s deafness came as a surprise for her parents. She had two sisters whom were also deaf. Deafness was hereditary in her family, however not everyone in her family was deaf. Marie’s father had one sister who was deaf and her mother had two siblings who were also deaf. When Marie was 11 months her parents noticed that she wasn’t responding to all noises. Her parents decided to test her hearing one day by creating noises behind Marie to see if she would respond. When Marie responded only to the loudest of noises, such as pots banging together, they found that at times she could hear with her right ear, but she could not hear anything out of her left.

The Optic cranial nerve is located in the eye. Its function is to provide us with vision. This particular cranial nerve is a sensory nerve. The hypoglossal cranial nerve supplies the muscles of the tongue and allows movements of the tongue to form things like speech and swallowing. This is a motor cranial nerve because it provides our tongue to move. The facial cranial nerve is mixed. Its sensory fibers are concerned with taste via taste buds in the front of the tongue. It also has motor fibers that control tears via the lacrimal glands around our eyes. These nerves also allow for muscles in our face to move and we can have facial expressions. The vagus cranial nerve is also mixed. Its sensory fibers allow for monitoring blood pressure and
The majority of the time I was with Mary we would read stories and do worksheets. Mary would do her best to read all of the words in the book. If she got stuck on a word, I would help her out. After I told her how to say a word or what it meant, she would repeat that word back to me so she would remember it. Mary caught on very fast to the material that we worked on. She would only have to ask about a word once and then she would recognize it if that same word came up again. She would ask questions when she did not understand a word or problem. I would do my best to explain to her what the question or word meant, and she usually understood. When we were talking and she did not remember what a specific word was in English, she would describe the word and use actions. I would guess the word and then she would continue on with our conversation. When Mary read out loud to me, her pace was slow and she would sometimes struggle with certain words. However, when she read to herself, which was in a whisper, she read at a normal to fast rate.
The nervous is considered to be the master controlling the systems of the body. The way it does this is to communicate through nervous impulse which is very rapid and very specific. The nervous system consist of the peripheral nervous system (PNS) and central nervous system (CNS). The peripheral nervous system consists of the cranial nervous, spinal nerves and ganglia. The peripheral nervous system can also be broking down into two categories which are somatic nervous system and parasympathetic system. On the other hand the central nervous system includes the brain and spinal cord. (fleming-Mcphillips, 2011)

Paramedics are frequently presented with neurological emergencies in the pre-hospital environment. Neurological emergencies include conditions such as, strokes, head or spinal injuries. To ensure the effective management of neurological emergencies an appropriate and timely neurological assessment is essential. Several factors are associated with the effectiveness and appropriateness of neurological assessments within the pre-hospital setting. Some examples include, variable clinical presentations, difficulty undertaking investigations, and the requirement for rapid management and transportation decisions (Lima & Maranhão-Filho, 2012; Middleton et al., 2012; Minardi & Crocco, 2009; Stocchetti et al., 2004; Yanagawa & Miyawaki, 2012). Through a review of current literature, the applicability and transferability of a neurological assessment within the pre-hospital clinical environment is critiqued. Blumenfeld (2010) describes 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.
