Cranial Nerve Palsy: with an Emphasis on Sixth Cranial Nerve Palsy Cranial Nerve Palsy With an Emphasis on Sixth Cranial Nerve Palsy I. What are Cranial Nerves? * Cranial nerves are nerves that come directly from the brain stem in contrast to spinal nerves which come from segments of the spinal cord. * There are twelve Cranial nerves in humans that fit this description. * They mainly serve the motor and sensory systems of the head and neck region; except for the tenth

Cerebral Lateralization and Functionality March 24‚ 2011 PSY/240 Studies have been conducted on cerebral lateralization and functionality of the human brain. Many studies have revealed there are no substantial differences of the left and right hemispheres of the human brain (Pinel‚ 2009). Some functional differences have shown one hemisphere may be slightly dominating for functional differences (Pinel‚ 2009). “It is widely believed that the left hemisphere has exclusive control over language

1. Ronald is experiencing a cerebral vascular accident also known as a CVA or in layman’s terms‚ he is experiencing a stroke. Cerebral vascular accidents are very serious medical emergencies that are life threatening. Stroke is a generalized term that explains injury or death of the brain tissue due to interruption of cerebral blood flow (Bledsoe‚ p.g.197). A stroke occurs when the flow of blood to a part of the brain is stopped completely or significantly reduced. With no oxygen supply from the

Bell’s palsy is a disease that causes paralysis in the muscles in the face. It affects the seventh cranial nerve that travels through a narrow canal in the skull which becomes inflamed‚ swollen or compressed. Typically subsides within one to nine weeks. When Bell Palsy occurs‚ the function disrupts the facial nerve‚ causing an interruption in the messages the brain sends to the facial muscles. The affected nerve causes weakness or paralysis on one side of the face‚ which leads the mouth to droop

“Bell’s palsy is an unexpected and rather sudden form of facial paralysis or severe facial nerve weakness that is most common but not limited to the ages of 15 through to 60.”[1] As evidenced in the photograph‚ “Bell’s palsy affects the facial nerves that control eye and mouth movement and frowning on one side of the face.”[2] The facial nerve or seventh cranial nerve controls most of the muscles in the face and parts of the ear. “This nerve travels through the narrow fallopian canal in the skull

Cerebral Lateralization and Functionality There are several methods for studying cerebral lateralization; four methods in the forefront are the study of unilateral lesions‚ sodium amytal‚ dichotic listening‚ and functional brain imaging. The traditional method for studying cerebral lateralization is unilateral lesions study‚ which is the study of the location and effect lesions have on the brain and body functionality. In past‚ this was primarily done after the subject was deceased or through

Parkinson’s Disease Before 1817 Parkinson’s disease was called “Shaking Palsy.” James Parkinson wrote a medical essay on the disease entitled “An Essay on the Shaking Palsy.” However‚ 60 years after‚ Jean Martin Charcot (1825-1893)‚ a French neurologist‚ discovered the importance of Parkinson’s essay and renamed the disease after Parkinson’s (Goetz 1). Parkinson’s disease is a long-term degenerative neurological condition that affects a person’s ability to control his or her own body movements

The point of this article was to show the consequences women face when they have an abortion in later pregnancies. In my opinion‚ this article is reliable since the studies were conducted by a physician from Mayo Clinic‚ not just an average joe guy trying to get his two cents in. I would definitely use this article in my research paper. I will use it when I discuss the

Throughout the time‚ humanity has developed one ability more than anything; the ability to communicate‚ verbally in particular. Language is an evolving concept for sure‚ because without the great vocabulary‚ humans would not be any different than monkeys. The ability to exchange information is shared by every communication systems‚ and a number of non-human systems share several features of human language. The primary difference between human and non-human communication is that animals are
