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 ...
An above-center hit on the cue ball is more precisely referred to as "follow" ("top" in the UK), while a below-center hit is "draw", "bottom", or "back-spin". Any time the cue ball is not struck directly in the center of the vertical axis, some sidespin will be imparted either left or right on the cue ball.
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 ...
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]
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 ...
Three games into his NBA comeback, Lonzo Ball is injured again. Thankfully, the injury's not to his problematic left knee that required three operations and forced him to miss two-plus seasons.
The upper motor neuron syndrome signs are seen in conditions where motor areas in the brain and/or spinal cord are damaged or fail to develop normally. These include spinal cord injury, cerebral palsy, multiple sclerosis and acquired brain injury including stroke. The impact of impairment of muscles for an individual is problems with movement ...
