Question

an accident case with brain injury is considered more critical than an accident case with fractured arm why

Answer 1

BECAUSE BRAIN IS THE MAIN AND SENSITIVE ORAGAN OF BODY AND IT IS THE CONTROLLER PART

Answer 2

Traumatic brain injury (TBI) refers to damage or destruction of brain tissue due to a blow to the head, resulting from an assault, a car crash, a gunshot wound, a fall, or the like.

In closed head injury, damage occurs because the person receives a blow to the head that whips the head forward and back or from side to side (as in a car crash), causing the brain to collide at high velocity with the bony skull in which it is housed. This jarring bruises brain tissue and tears blood vessels, particularly where the inside surface of the skull is rough and uneven; damage occurs at (and sometimes opposite) the point of impact. Thus, specific areas of the brain - most often the frontal and temporal lobes - are damaged. This focal damage often can be detected through MRI and CAT scans.

In closed head injury, the rapid movement of the brain can also stretch and injure neuronal axons - the long threadlike arms of nerve cells in the brain that link cells to one another, that link various parts of the brain to each other and that link the brain to the rest of the body. This widespread axonal injury interrupts functional communication within and between various brain regions and sometimes between the brain and other body parts. However, this type of diffuse damage typically cannot be detected through currently available imaging technology (but with new developments, this may change). Its existence is very clear, however, in the widespread effects it has on the

individual's functioning.
