Question

1. connections between systems
2. how do the muscles and bones work together to help the body move?
3. give one example from the video of how an injury or problem in one system can affect the other.
4. vocabulary check

write a short definition (in your own words) for each term:

• joint:
• tendon:
• ligament:

Explanation:

1. Muscles contract and pull on bones at joints to enable movement. Bones provide a rigid structure and attachment points for muscles.
2. For example, a torn tendon (connects muscle to bone) can limit bone - movement as the muscle can no longer effectively pull on the bone.
3. Joint: The place where two or more bones meet, allowing movement. Tendon: A tough band of tissue that connects muscle to bone. Ligament: A tough band of fibrous tissue that connects bone to bone, providing stability to joints.

Answer:

1. Muscles contract and pull on bones at joints to create movement.
2. A torn tendon can limit bone - movement as the muscle - bone connection is disrupted.
3. Joint: The junction of two or more bones enabling movement.

Tendon: Tissue connecting muscle to bone.
Ligament: Tissue connecting bone to bone for joint stability.
