Introduction
The cranial nerves are significant nerves that relay information between parts of the body of an individual and the brain. Significantly, the nerves' origin is in the brain allowing the coordination of activities between the neck and the head. The damage of these nerves causes a significant effect on the function of the body parts, including (Fuller, 2019). The damage affects senses, including smell, touch, vision, and hearing.
Procedure
The experiment involved the use of salty and sugary water, and testing of sound by placing a struck tuning fork. Additionally, penlight was used on both aria and the lab partner as well as the movement of both subjects in straight lines.

Results
The experimental subject who is aria shows various symptoms as a result of the head injuries from her accident. For instance, she can differentiate between sweet and salty, which shows defects in her taste sensation. Additionally, there is a significant inability to move her eyelids and to move generally in perfect body balance. Using a control subject, which is my partner, it’s clear that there are severe defects. For instance, my partner recognizes that the drink given to him has salt instead of sugar. Aria is unable to tell what the water tastes like. Also, once a spotlight is pointed towards the partner’s eyes, he immediately shuts his eyelids and contorts the brows in response to the irritation. Still, arias reflex to this situation is slower. The control subject shows considerable balance walking in a straight line as opposed to aria, who feels weak and has to hold on to objects to maintain balance.
Discussion
Significantly, the experimental subject’s data shows that there is considerable damage to the facial nerve. Arias's indication of weakness on the right forehead, eyebrows, and lids is a result of this nerve damage. Additionally, this damage to the facial nerve is what is affecting her conveyance of taste (Fuller, 2019). Also, regarding taste, her glossopharyngeal nerve is damaged. Concerning her equilibrium, the vestibulocochlear nerve is damaged. The damage on this nerve explains her right ear's inability to hear after placing the struck tuning fork on her forehead. This damage is also responsible for her fatigue and imbalance during movement (Fuller, 2019). The experimental subject is suffering damage to multiple cranial nerves.
