Closed head injury (coup contrecoup) can damage more than the impact sites on the brain, as axon bundles may be torn or twisted, blood vessels may rupture, and elevated intracranial pressure can distort the walls of the ventricles. [7] [10] [11] Diffuse axonal injury is a key pathology in concussive brain injury. [5] The visual system may be ...
If the impact causes the head to move, the injury may be worsened, because the brain may ricochet inside the skull causing additional impacts, or the brain may stay relatively still (due to inertia) but be hit by the moving skull (both are contrecoup injuries). Specific problems after head injury can include [4] [5] [6]
Whiplash, whose formal term is whiplash associated disorders (WAD), is a range of injuries to the neck caused by or related to a sudden distortion of the neck [1] associated with extension, [2] although the exact injury mechanisms remain unknown. The term "whiplash" is a colloquialism. "Cervical acceleration–deceleration" (CAD) describes the ...
Injury can be described as a ‘mechanical disruption of tissues resulting in pain.' [13] Despite the fact tissues can self-repair, muscle degradation occurs after repeated and prolonged use. [13] Overuse and strain injuries can occur at work, physical activity and daily life. [ 11 ]
Myalgia or muscle pain is a painful sensation evolving from muscle tissue. It is a symptom of many diseases . The most common cause of acute myalgia is the overuse of a muscle or group of muscles ; another likely cause is viral infection , especially when there has been no injury .
Concussion, a type of mild traumatic brain injury that is caused by a direct or indirect hit to the head, body, or face is a common injury associated with sports and can affect people of all ages. A concussion is defined as a "complex pathophysiological process affecting the brain, induced by biomechanical forces". [ 1 ]
The ball bounced out of the trees and back into the fairway before coming to a stop. Per the report, Rahm yelled "Fore Left" immediately after striking the ball. At the time, few outside of Steele ...
Also shown are the insular cortex (purple), the brain stem (black), and the cerebellum (blue). The frontal lobe of the human brain is both relatively large in mass and less restricted in movement than the posterior portion of the brain. [1] It is a component of the cerebral system, which supports goal directed behavior. [2]
