A hard blow to the head can
shake your brain inside the skull

How many concussion is too many?
Although
there isn’t a set answer
as to how many concussions is too many, there are different variables that determine when concussions could turn into permanent damage. As the number of concussions suffered increases, so does the risk for developing long-term damage.
What is the most sensitive part of the head?
The Prefrontal Cortex
Is the Most Sensitive Place in the Frontal Lobe. Within the frontal lobe, the most susceptible area to injury lies at the very front of the brain behind the skull. This small area of the brain largely controls the personality-creating functionality mentioned earlier.

All head injuries are
potentially serious because they may damage the brain
. A head injury may cause damage to the brain tissue, a skull fracture or an injury to the spine or neck.

. When a person has a blow to the head, their brain can be shaken inside the skull as well. This may cause a more serious head injury which may make them feel sick or drowsy.
What is a remote TBI?
Remote moderate-to-severe TBI is
a risk factor for motor dysfunction
—defined as recent falls and impaired posture/gait—among older veterans. TBI-exposed older adults may be ideal candidates for aggressive fall-screening and prevention strategies.
What is a Dai brain injury?
What is diffuse axonal injury (DAI)? Diffuse axonal injury is
the shearing (tearing) of the brain’s long connecting nerve fibers (axons)
that happens when the brain is injured as it shifts and rotates inside the bony skull. DAI usually causes coma and injury to many different parts of the brain.

contusion
causes bleeding and swelling inside of the brain around the area where the head was struck. Contusions may occur with skull fractures or other blood clots such as a subdural or epidural hematoma.
What happens if you have 3 concussions?
Athletes who have sustained three or more concussions are more likely to have
long-term cognitive impairment and emotional struggles

Which body part of a man is most sensitive?
The head of the penis (glans)
has about 4,000 nerve endings which makes it one of the most erogenous zones of the male body.
What part of the female body has the most nerve endings?
There are more than 8,000 nerve endings in
the tip of the clitoris
alone. That’s double the number of those in a penis.
What part of the body Cannot feel pain?
The brain itself does
not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
What is classification of head injury?
Head injuries may be categorized in several ways. Injuries are classified by
mechanism (closed vs. penetrating injury)
, morphology (fractures, focal intracranial injury and diffuse intracranial injury), and severity (mild, moderate and severe).

scalp injury, skull fracture, and surface contusions
and are generally be caused by contact. Diffuse injuries include DAI, hypoxic-ischemic damage, meningitis, and vascular injury and are usually caused by acceleration-deceleration forces. These 2 forms of injury are commonly found together.
What is a diffuse injury?
Diffuse injuries, also called multifocal injuries, include
brain injury due to hypoxia, meningitis, and damage to blood vessels
