Help with mastering bio for anatomy

Background: While backpacking with friends, Jorge decided to cool off by diving into a river that was shallower than he realized. His forehead hit a submerged boulder, forcing his head backward. Stunned and in pain, Jorge tried to climb out of the water. One of his friends yelled for him to lie down and let them help him out.

Questions:

Part D - Neck injury One of Jorge's friends was taking an EMT (Emergency Medical Training) course and insisted that Jorge lay still and not move his head. What might he be concerned about? View Available Hint(s) Compressive forces from the impact could have pushed in the occipital bone, causing brain damage. Hyperflexion of the neck from the impact could have caused a separation between the cervical vertebrae, causing a tear in the spinal cord Hyperextension of the neck from the impact could have fractured cervical vertebrae and potentially damaged the spinal cord Damage to the orbit could have resulted in the eye becoming detached from the optic nerve

Explanation / Answer

1. Option third is the correct answer. Impact of forhead with boulder will cause hyperextension of the neck (the neck is extended, as in looking upward toward) not the hyperflexion (the movement in which the chin is lowered down toward the chest). Cervical vertebrae (vertebra in the neck region) of the spinal colum are the thinnest and most delicate bones having huge jobs of supporting the head, protecting the spinal cord, and providing mobility to the head and neck.

2. Option first that is twelve is the correct answer. There are twenty four ribs found in the human body divided into two sets of twelve curved, flat bones.

3. Option 3rd that is lacrimal is the correct answer. Lacrimal bone is just present lateral to the eyes. Frontal bone is situated above side of the eye. Maxilla, zygomatic and sphenoid bones are situated lower side of the eyes.
