How Skeletal Muscles Produce Movements

How do skeletal muscles produce movement?

• By contracting and pulling on bones

• By expanding and pushing on bones

• By vibrating and creating waves

• By generating electrical impulses

What do tendons do to produce movement?

• Tendons connect muscles to bones and transmit the force generated by muscles to produce movement.

• Tendons connect bones to other bones and stabilize joints.

• Tendons store energy and release it during movement.

• Tendons produce electrical signals to stimulate muscles.

Most muscles cross at least how many joints?

• Most muscles cross at least one joint.

• Most muscles cross at least three joints.

• Most muscles cross at least four joints.

To what are skeletal muscles usually attached?

• Bones

What happens when skeletal muscles contract?

• The muscles shorten and generate force.

• The muscles lengthen and relax.

• The muscles become rigid and immobile.

• The muscles disintegrate.
