Title Anatomical variation of the superior thyroid artery and its relation to the external laryngeal nerve. Introduction The thyroid gland is the largest endocrine gland located in the anterior triangle of the neck. It consists of two lobes, right and left, connected by an isthmus in the middle. The thyroid gland is mainly supplied by the superior thyroid artery, the first branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk of the…

Georgina Casey, nursing lecturer at Auckland University of Technology, writes that bioelectronic medicine is an internal or external therapy that targets a particular area of the body and disrupts action potentials through electrical impulses, affecting nerve function. This has elicited numerous novel treatments, notably…

In today’s world it seems like there is a growing number of people that are being plagued with mental health diseases. In particular Alzheimer’s appears to affect a growing number of people each year. Alzheimer’s is considered to be the “sixth leading cause of death in the United States today” (Latest Alzheimer 's Facts and Figures, 2016). While many research is being conducted to figure out the best way to combat this, there seems to be one deterrent that stands above all. This deterrent…

cervical fusion procedure done. This is a surgery that removes a herniated or degenerative disc in the neck. According to Ullrich (2014), “An anterior approach cervical fusion is performed to relieve neck pain and other paid due to spinal cord or nerve root pressure from a cervical disc herniation.” The plaintiff, Irene Perin believe that the surgeon injured her and caused her to suffer from paralysis vocal cord. This injury had a major effect on Ms. Iren Perin’s voice. Her argument was…

Medical devices can range from the most simple thermometers to complex imaging systems such as magnetic resonance imaging (MRI). Neuromodulation is technology that acts upon nerves directly. It delivers electrical or pharmaceutical agents to a specific target area by altering the nerve activity. Neuromodulation devices and treatments are very effective (X). They treat nearly every disease like headaches to tremors to spinal cord damage to urinary incontinence. With a lot of scope…

Mobility disability is an early sign of the disability process in older people and is associated with adverse health problems such as arthritis, cardiovascular disease and number of comorbidities (Melzer et al., 2005). It is a precursor of end stage disability in older adults and is more common is women (Fried et al, 2000; Zunzunegui et al, 2015). Due to our rapidly aging population and loss of functional independence, identifying risk factors that predict mobility disability in elderly people…

2009). Concept 9: Cranial Nerves : This concept taken from the Public Health Nursing Block 5, module 08 entitled as “Assessment of Central Nervous System Examination”. Cranial nerves are the nerves that emerge directly from the brain it directly incudes in the part brainstem. Cranial nerves exchange information between the brain and parts of the body, primarily to and from regions of the head and neck. The cranial nerve emerges from the central nervous system. Each cranial nerves having pairs…

palsy which could cause the cranial nerve VII damage and any asymmetry with the central brain damage. There was no edema around the eyes (periorbital). The normal findings were appropriate to the age, the face was symmetrically intact to the eyebrows, the palpebral fissures, and the nasolabial folds. Pain denied in both sides. If it there was any pain in any side of the face, it could be marked as the trigeminal neuralgia (tic douloureux) which causes by the V cranial nerve. “Trigeminal…

having a stroke and Bell’s palsy? What causes these conditions and what cranial nerve(s) do these conditions affect (including their branches)? What muscles of facial expression are affected (name the muscles and the facial expression(s) that would be altered, i.e., levator…

This nerve plays an extremely important role in many functions however the most important is swallowing and phonation. The vagus nerve has many branches which goes to many different organs of the body. The vagus has 3 main branches, the pharyngeal, superior laryngeal, and recurrent laryngeal nerves. That are very important to phonation. The pharyngeal nerve innervates muscles of the soft palate and the pharynx. The superior laryngeal and the recurrent laryngeal nerves carry nerve impulses to…
