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]
Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema. [6]
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]
In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
Lonzo also speculated that years of training on the hard concrete of Chino Hills State Park could have played a role in the cartilage issues that have hammered his career.
The goal of the game is to earn a required number of points, before one's opponent does, by using one's cue ball to cause the opponent's cue ball to knock over pins (and to not do so with one's own cue ball), and by contacting the red object ball with either cue ball, after one's own cue ball has contacted that of the opponent, and/or by ...
