concussion, which is when the head rapidly rotates from one side to another causing cutting or damaging of tissues in the brain. So, what type of damage does this cause in the brain? Simply, it damages the nerve cells of the brain, inhibiting the axons from transporting brainwaves, and in serious cases, can cause cerebral hemorrhaging. These injuries can cause anything from little short term repercussions to long term degenerative damage and death (Powell 2001). What are the symptoms of a…

Tisdall A 21-year-old female presents to the clinic with a headache and diplopia. The headache started one week ago and is worse in the morning. She describes the pain as generalized and throbbing in nature. No triggering factors are identified, but the headaches are associated with nausea and now, double vision. She has never had these symptoms before. She denies drowsiness, incontinence, cognitive disturbances and any congenital head abnormalities. Review of system A physical evaluation is…

For this lab report the class goal was to figure out if our dominate hand is stronger than our non-dominate hand. There are a few factors that come into play when measuring this, the first thing that is important to know is what a muscle is and how it works. According to Medicine net a muscle is “the tissue of the body which primarily functions as a source of power.” A muscle is also used for movement and keeping body parts in their right positions. There are 3 different types of muscles,…

Unit 4 – Fiona Bennett Brain Science In this unit I will be investigating the structure of the brain. The human brain is responsible for everything that happens in our bodies. On average the brain weighs 1.5 kilograms. It is one the most complex organs in the human body. The brain controls everything from coordinating movements to constructing sentences and even simple things like breathing. The brain is supplied with oxygen to keep it alive by a network of blood vessels. Structure of the brain…

First, Speeding means trying to get somewhere quickly and going over the speed limit when you are on the interstate the standard speed limit is seventy miles per hour for rural interstates and forty five miles per hour is the minimum speed limit. The speed limit for most business and residential area is twenty five miles per hour and on secondary roads the speed limit for trucks is forty five and for other vehicles it is…

Thinking is human being’s high-grade psychological activity, as we move through adolescence, adolescent’s brain undergoes extensive remodeling, resembling a network and writing upgrade. For started, the brain’s axon passes messages away from the cell body to other neurons. Gradually, axons become more insulated with myelin, eventually boosting the axon’s transmission speed up to hundred times. Meanwhile, dendrites which receive messages from other cells grow twiggier, and the most heavily used…

Homework chap 3 lifespan Chap 3 Assignment Questions 1. Explain how sleep patterns are characterized over the course of life: infancy, childhood, adolescence/emerging adulthood and adulthood/aging (briefly for each of the 4 stages When we consider the sleep patterns during infancy, we have learned that newborns need approximately 16 to 17 hours a day but, some sleep more than others. Newborns sleep is sporadic: so the need to eat and to change diaper might modify the sleep pattern. Although,…

disease are inherited from the patients parents. The main issue with ALS is the death of both upper and lower motor neurons in the brain. the brain stem, and the spinal cord. Motor neurons develop protein rich inclusions in their cell bodies and their axons. Protein degradation takes part in these…

influences the development vulva (Ferguson and Horvitz, 1985). There are many types of lim not currently being pursued in our experimentation: lim-4, and lim-6. A defect in lim-4 results in defects in odorsensory neurons and controls the shape of the axon for a specific motor neuron. When the lim-6 gene is not correctly functioning in the C. elegans the neurons are affected, it is tied to the neurotransmitter GABA and can impact that signaling pathway. lim-6, deals with the uterus of the…

brain parenchyma. Usually associated with gross brain oedema with poor prognosis. c. Intraparenchymal haematoma with contusion. d. Intraventricular haematoma: Haemorrhage into the ventricles. 4. Diffuse axonal injury: Global frictional injury to the axons resulting in unconsciousness with no macroscopic brain injury. Clinical features suggestive of head injury: 1. Loss of consciousness (may be very brief) 2. Vomiting (particularly persistent) 3. Nasal & ear bleed. 4.…
