Functional Anatomy Week 1

What is the ability of a muscle to shorten when stimulated called?

• Elasticity

• Contractibility

• Extendibility

• Flexibility

Which characteristic allows muscles to stretch beyond their resting length?

• Contractibility

• Elasticity

• Extendibility

• Stability

What type of contraction occurs when a muscle shortens during movement?

• Isometric

• Eccentric

• Concentric

• Static

What typically happens to the antagonist muscle during a concentric contraction of the agonist?

• It contracts at the same time to assist the movement

• It relaxes to allow the movement to occur

• It becomes the new agonist

• It shortens and lengthens simultaneously

What is the name of the muscle attachment that moves during contraction?

Which type of contraction involves no change in muscle length?

• Dynamic

• Concentric

• Eccentric

• Isometric

What is the term for the muscle that provides the main force for movement?

• Agonist

• Antagonist

• Stabiliser

• Synergist

What is the role of the antagonist muscle during movement?

• Initiates movement

• Contracts with the agonist

• Becomes the insertion point

• Opposes the agonist

A gymnast performs a split. Which muscle characteristic is being demonstrated?

During a bicep curl, what type of contraction occurs as the dumbbell is lowered?
