The episodes of numbness in the chin and lower lip and the sensations of prickling (pins and needles) at the right corner of her mouth are due to the alterations in the functions of somatic nervous system. Hypoesthesia is a state of loss or decreasing the capacity of sensation in general and skin in particular. The hypoesthesia is characterized by an insufficient response against the stimulus. Paresthesia is state where the individual felt a sensation of numbness or creeping. It usually occurs in the extremities of limbs and other parts of the body such as mandible or upper jaw. In paresthesia, the individual show an appropriate response against the stimulus. From the above classification (Fig-1), the disorders (e.g., neuropathy) of somatic …show more content…

The third and terminal branch of the trigeminal nerve (inferior alveolar nerve) that supply to the mandible is being affected to show the episode (Giuliani, Lajolo, Deli, & Silveri, 2001). In addition, the second branch of the trigeminal nerve (maxillary nerve) to show the effects. The nerves are also responsible for skin innervations. Therefore, Mary had experienced numbness and loss of sensation.

Fifth cranial nerve (trigeminal nerve) is affected to show the episode. The feeling of stabbing pain in upper jaw and teeth and slowly radiating towards nose is due to defective function of the maxillary nerve. The nerve is the second branch of trigeminal nerve. The initiating or trigger point is the loss of sensory or motor function of the second branch of fifth cranial nerve (Richard & Sanders, 2010)

The following are the cranial nerves that involve in regulation of functions of eye o Optic nerve: The sensory nerve is a second cranial nerve help in whole process of sight and vision. The nerve involves in the transmission of electrical signals from the various parts of eye to CNS (brain), then the brain send an appropriate response in the form of an image to see (the objects what we see around us). The defects in the cranial nerve (optic nerve) such as inflammation (neuritis) can cause the alterations in normal vision and sometimes even cause …show more content…

One group arises from the apex of the orbit to attach to the sclera anterior to the equator of the eye (rectus muscles- medial, lateral, superior and inferior) and second group consists of the oblique muscles (Double vision, 2012). The extra-ocular muscles are supplied by cranial nerves (the third, fourth or sixth cranial nerves). Among the cranial nerves, the nerve responsible for double vision is abducens nerve when she looks right. The probable cause for the double vision is the presence of lesions in the nerve. Since the lesions occur only in the nerve (branch) that supply the right eye not to the left eye. Therefore she was not experienced any double vision towards left

The inability to purse the lips and show the teeth of the affected side is due to paralysis of which muscle? The inability to purse the lips and show the teeth of the affected side is due to paralysis of the orbicularis oris facial muscle, which is innervated by the facial nerve (N VII). b. The absence of the mimic expression of smile and laughter is the result of the dysfunction of numerous facial muscles; name four.

Synesthesia is a unique condition in which stimulation of one sensory pathway causes a response from another sensory pathway. The Man Who Tasted Shapes tells the story of the experiments performed by neurologist Richard Cytowic and his experiments on a man with synesthesia. In the book, Cytowic recalls the first time he heard about synesthesia while working as a resident in a hospital and is brushed off by his coworkers who can not imagine a condition with no physical signs. This leads to Cytowic’s philosophical consideration of whether or not synesthesia matters in a clinical setting. Since the book was published, copious amounts of new research has emerged about the condition, making it more widely-recognized in the field of psychology and

DOI: 8/12/2015. Patient is a 38-year old male journeyman carpenter who sustained injuries to his right cheek/lips/jaws and shoulders/upper back when he was struck by a hook that broke from come-along pin. Based on the initial evaluation report dated 03/09/16, the patient complains of jaw pain aggravated by chewing, mouth pain aggravated by biting, face pain worse with chewing and right shoulder pain increased with lifting and overhead work.

The purpose of my paper is to discuss the history of Congenital Analgesia and its presence in the human body. Congenital Analgesia, also referred to as Congenital Insensitivity to Pain or CIP, is a rare neurological disorder of the nervous system that prevents a person from being able to feel pain. Congenital Analgesia results from the “lack of ion channels that transport sodium across sensory nerves. Without these channels, nerve cells are unable to communicate pain” (Hamzelou, 2015, p. 1). While the body does not respond to extreme changes in temperature or bodily harm and damage, those with Congenital Analgesia can still process normal sensations such as body-to-body contact or joint movement.

There are twelve pairs of cranial nerves. Each pair has a name and a Roman numeral assigned to it. These nerves are developed in utero during gestation. These nerves leave the brain and pass through the foramina of the skull in order to travel to the sensory organs or to the muscles of the head and neck that they innervate. Cranial nerves may serve motor functions, sensory functions, or both.

Patients are weighed to determine if there are signs of abnormal weight loss. The physician checks the patients’ eyes, ears, head, thyroid gland (front of neck), abdomen, hands, feet, arms, and legs. To check patients’ motor and sensory systems, reflexes, cranial nerves, gait, and coordination, a neurological exam (nervous system) is conducted. Cranial nerves relay information between the brain, head, and neck and control the sensory and motor functions, such as facial movement, vision, hearing, smell, and taste. The motor function controls movement and

The disruption may manifest as aphasia. There are four major aphasia syndromes, namely Broca’s aphasia, Conduction aphasia, Wernicke’s aphasia and Anomic aphasia. These aphasia syndromes have different characteristics and causes. In this paper the four accepted types of aphasia are described and their aetiology and characteristics are illustrated.

The fibres first pass in a dorsomedial direction and then loop over the abducent nerve and produce a small round swelling in the floor of the 4th ventricle. The superior salivary and lacrimatory nuclei of the facial nerve are also present in the lower half of the of pons. These nuclei are small collections of cholinergic nerve cells in dorso-lateral reticular formation. The neuron of these two nuclei seems to be intermingled with each other.
