Which function of the skeletal system would be especially important if you were in a car accident?
- storage of minerals
- protection of internal organs
- facilitation of movement
- fat storage
Introduction:
The skeletal system functions to provide support and movement to the body. In addition, it also renders protection to the vital and delicate organs of the body.
Answer to Problem 1RQ
Option (b) is the correct answer. The function of the skeletal system that would be specially important in a car accident is protection of internal organs.
Explanation of Solution
Justification for correct answer:
Option (b) is protection of the internal organs. The skull is a hard casing made of bones that protects the brain. The rib cage protects the visceral organs like heart, lungs, stomach, liver and others. The vertebral column protects the spinal cord. Thus these bony stuctures function to protect the vital organs of our body. During an accident these bony cages act as shield to the internal organs and protect them from severe damage. Hence, option (b) is the correct choice.
Justification for incorrect options:
Option (a) is given as storage of minerals. This is a long term function of the bones of the skeletal system. It is not related to protection in emergency situations like a car accident. Hence, option (a) is incorrect.
Option (c) is given as facilitation of movement. Movement provided by the skeletal system helps in day-to-day activities. A car accident is a situation of trauma where movemnet of body parts gets restricted due to psychological impact. More than movement protection is important in this situation. Hence, option (c) is incorrect.
Option (d) is given as fat storage. Fat storage by skeletal system has no role in protection. The adipose fat deposits under the skin provide cushion to internal organs from mechanical shock. Hence, option (d) is incorrect.
During an emergency like car accident, the strong bony structures like the skull, rib cage and vertebral column protect vital internal organs from major injuries.
