Introduction: A concussion is a mild form of traumatic brain injury (TBI) caused by a sudden or violent blow, bump, or jolt to the head. Concussions can also occur from a fall or a blow to the body that causes the head to move rapidly back and forth. These types of sudden or violent impacts make the brain accelerate inside of the skull, in movements called coups and contrecoups. These movements lead to the brain striking the front and back of the skull, damaging the delicate and vital organ. The
recent studies, it has been found that concussions resulting from athletics are becoming increasingly dangerous while at the same time given less consideration. Sports related mild traumatic brain injuries in children have increased by sixty percent in the last decade. Approximately 173,285 cases of mild traumatic brain injuries relating to sports are treated each year in U.S. emergency departments (CDC). One may ask just what exactly a concussion is. A concussion can be defined as a clinical syndrome
452) The prefrontal area of the frontal lobe is responsible for goal-oriented behavior, short-term or recall memory, and the elaboration of thought and inhibition on the limbic areas of the CNS. (p.452) 2. Know the function of the arachnoid villi. The arachnoid villi function as one-way valves directing CSF outflow into the blood but preventing blood flow into the subarachnoid space (p.461) 3. Where is the primary defect in Parkinsons disease and Huntingtons? The inferior-most portion of
gland, functions much like the limbic system by influencing the secretion of melatonin associated with circadian rhythms. Controlling thought? (pg. 452) They parietal lobe is involved in sensory association (storage, analysis, and interpretation of stimuli). Emotions and behavior? (pg. 453) The hypothalamus is responsible for 2 major functions (1.) maintenance of a constant internal environment (2.) implementation of behavioral patterns. Integrative centers control ANS function, regulation
and posture. ! 2. Know the function of the arachnoid villi. 3. Where is the primary defect in Parkinsons disease and Huntingtons? - (Pg 459) The inferior most portion of the basal ganglia is the substantia nigra, which synthesizes dopamine, a neurotransmitter and precursor of norepinephrine. Its dysfunction is associated with Parkinson’s disease. Parkinsons and Huntington’s are both defects of the basal ganglia. P. 564-565 ! 4. What is the function of the CSF? Where is it produced
