Cranial nerves

we can feel things and respond in appropriate ways. A review of the cranial nerves was very insightful and discussed the adverse impacts when certain nuclei within cranial nerves are severed. For instance, depending on the cranial nerve and nuclei severed, a person might not be able to look laterally or medially. Knowledge of Neuroscience helps practitioners deal with patients better since dentists work so close to cranial nerves. For instance, if a patient is going to undergo implant surgery,…

system consists of the brain, spinal cord, 12 cranial nerves that come from the brain and other various nerves that arise from the spinal column (University of Rochester Medical Center [URMC], 2014). A thorough neurological examination is important to detect underlying problems that can cause delay or deficit in the normal development and functioning of an infant (URMC, 2014). This paper will discuss the proper examination of behavior, cranial nerves, tone, positioning, reflexes, head sutures…

The special senses are hearing, equilibrium, vision, taste, and smell. Hearing is associated with the ear and how the sound waves travel through from external to internal ear. The external layer of the ear consists of the auricle, external acoustic meatus, and the tympanic membrane. Sound enters through the auricle, which carries the sound waves to the external acoustic meatus (i.e. ear canal). The external acoustic meatus in turn carries the sound waves to the tympanic membrane (i.e. eardrum).…

There are two types of diabetes insipidus, one is cranial diabetes insipidus and the other is nephrogenic diabetes insipidus. They both differ from each other. Cranial diabetes insipidus is caused when the body does not produce sufficient ADH, hence excessive amounts of water is lost during urination. Whereas, the nephrogenic diabetes the ADH is produced at…

1. A salivary gland is stimulated by its parasympathetic nerve. a) Describe the organization of the parasympathetic division of the autonomic nervous system The autonomic nervous system (ANS) is a part of the peripheral nervous system that largely acts involuntarily. It consists of nerves in cardiac muscle, smooth muscle, exocrine and endocrine glands. The main visceral activities are temperature regulation, digestion, blood pressure and genitourinary function. The second main division of the…

along with treatment. What is Bell’s Palsy? According to The National Institute of Neurological Disorders and Stroke “Bell’s Palsy is a form of temporary facial paralysis resulting from damage or trauma to the nerves (Bell's Palsy Fact Sheet, 2003)”. The nerve affected is seventh cranial nerve and it is responsible for normal muscle function; for example, blinking, chewing and smiling etc. Bell’s Palsy was named after Scottish surgeon Sir Charles Bell in the 19th century, he first discovered…

is beneficial for several reasons. From a clinical standpoint, pre-operative local nerve blocks decrease the level of intraoperative and postoperative pain and result in smoother recoveries (Woodward 2008). Multimodal analgesia may encompass administration of opioids, tranquillizers, and local anaesthetic agents as adjuncts to general anaesthetic agents. Common side…

Institute of Health (NIH) bell’s palsy occurs when the facial nerves (cranial nerves) which controls the muscles for facial expression is weak or swollen and therefore paralyses the one of one side of the face or the whole face in rare cases. It usually occurs without signs or warning with severe pain. The name Bell’s palsy was named after Scottish surgeon Sir Charles Bell (1774-1842) when he first described the connections of the facial nerves. Let me quickly tell you my first experience. One…

researchers have turned to a treatment that would be more cost and time effective for the patient. This treatment was approved by the Food and Drug Administration(F.D.A.) and is known as Cranial Electrotherapy Stimulation (Food and Drug…

into Central Nervous System (CNS) and Peripheral Nervous System (PNS). Central nervous system controls all important nerves inside the body enable the body to do its daily tasks. Peripheral nervous system is the system that control on the outside the brain and spinal cord. Both systems are requiring in the body for different functions. The central nervous system consists of the nerves in brain and spinal cord. The brain is responsible for organize and coordinate the information. Consciously and…
