Chapter 24, Problem 2PL
The abdominal wall muscles possess the following functions except
a. extend the spine.
b. compress the abdominal visceral organs.
c. assist in forceful exhalation.
d. help maintain posture.
Expert Solution & Answer
Summary Introduction
Introduction :
The muscles are the bundles of the fibrous tissues in the animals that have the ability to contract, movement, and maintaining the position of different parts of the body. There are three types of muscles, smooth, cardiac, and skeletal muscles. The muscular system is controlled by the nervous system and some muscles are autonomous.
Answer to Problem 2PL
Correct answer :
Option (a), extend the spine.
Explanation of Solution
Explanation/justification for the correct answer :
Option (a) is extend the spine. The deep back muscles help in the extension of the spine and maintain the body posture. Hence, this option is correct.
Explanation for incorrect answer :
Option (b) is compress the abdominal visceral organs. The abdominal wall muscle compresses the abdominal visceral organs against the diaphragm. Hence, this option is incorrect.
Option (c) is assist in forceful exhalation. As the abdominal wall muscle push back the abdominal visceral organs against the diaphragm, it results in forceful exhalation. Hence, this option is incorrect.
Option (d) is help maintain posture. The abdominal wall muscle also helps in maintaining the body posture. Hence, this option is incorrect.
