If a tree branch is cut, the surrounding branches may grow enough to fill in the empty space left by the missing branch. When this same type of event occurs in the nervous system following brain damage, it is called:
A) hemiplegia.
B) denervation supersensitivity.
C) collateral sprouting.
D) tree branching.

The correct answer to the following question will be Option C (Collateral sprouting).

Explanation:

Therefore, Option C is the right answer.

C) collateral sprouting.

Explanation:

The collateral sprouting can be defined as the process by which the motor axons send signals to the axon terminus typically in the case of denervated muscles to reinnervate the muscle fibers. This process helps in restoration of the muscle power.

This is a quick process to recover from the axon loss during an injury and due to degeneration.  

This is a natural mechanism and is clinically effective in the process of restoring the function when the axons are injured.

The collateral sprouting is just like the process when tree branch is cut and other branches grow to fill up the empty space of the missing branch.

answer:

d. because dr. laguardia selected a widely used measure, his study generalizes to has strong external validity. external validity has limited external validity. other applications of this measure.

the widely used measure that he applied to his experiment was the benton facial recognition test. it employed on to football players and as result, only players who suffered brain concussions did not pas this test. and although it has an external validity, it is limited because it isn't general to apply to other population.
