What is the function of antagonistic muscle pairs?

• To increase the speed of muscle contraction

• To move parts of the body in opposite directions

• To stabilize joints during movement

• To work together to produce the same movement

Which type of muscle pattern is characterized by fibers running parallel to the direction of the muscle?

• Convergent

• Pennate

• Sphincter

• Parallel

What is the primary function of tendons in the muscular system?

• To store energy

• To protect muscle fibers

• To connect muscles to bones

• To produce muscle contractions

Which of the following is true about pennate muscle fibers?

• They are arranged concentrically around an opening.

• They run parallel to the muscle direction.

• They fan out from a common point of attachment.

• They have one or more tendons running through the muscle.

What is the role of fascia in muscle structure?

• It surrounds and separates skeletal muscles.

• It is the innermost layer of muscle tissue.

• It wraps individual muscle fibers.

• It connects muscles to bones.
