Concept explainers
Muscles that oppose one mother are
a. synergists. c. hateful. e. fixators.
b. levers. d. antagonists.
Introduction:
The parts of the human body can move because of the muscles that are the soft tissues in their bodies. These tissues are made up of proteins like actin and myosin. Other than the movement, the role of muscles is to stabilize the joints, and it also maintains the posture of the body.
Answer to Problem 1RAC
The correct answer is option (d) antagonists.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) antagonists. The two groups of muscles are agonists and antagonists. The group of muscles that opposes the action of another group of muscles are known as antagonists. For example, the extension of the elbow at the arm results because of the triceps brachii, whereas the bending of elbow results because of biceps brachii flexes. In the elbow flexion, biceps brachii and triceps brachii works in opposite manner so, the antagonist of the triceps brachii is biceps brachii. So, the correct answer is option (d).
Explanation for incorrect answer:
Option (a) synergists. Some muscles work in a group for accomplishing specific movements; these muscles are known as synergists. For example, the muscles that help in the flexion of the shoulder are the deltoid, biceps branchii, and pectoralis. These muscles do not oppose function of another muscle. Hence, the given option is not correct.
Option (b) levers. The work of muscles and their bone are performed through the levers. Levers can be described as the machines that are made up of rigid pole which are able to move and pivot at a stationary hinge. These muscles do not oppose the function of other muscles. Hence, the given option is not correct.
Option (c) hateful. The muscles are categorized into two terms, agonists and antagonists. Some muscles oppose function of one another and work in opposite manner, the term that is described to such muscles is antagonists. The term hateful is not appropriate for describing these muscles. Hence, the given option is not correct.
Option (e) fixators. The muscle that acts as a stabilizer while moving another part, that muscle is known as fixator muscle. These muscles make the work of agonist efficient, but these do not oppose their function. Hence, the given option is not correct.
Antagonists are the muscles that oppose one another. Hence, the correct answer is option (d) antagonists.
