4. Cross out the statement(s) that are NOT true.
- The skeleton:
-
-
- supports and protects the organs of the body
- provides a means of locomotion
- grows throughout the life of the animal
- helps keep the level of calcium ions in the body constant
- develops from the cartilage laid down in the fetus
-
5. True or False. If false indicate the correct answer.
-
- The elbow joint is a synovial joint
- The patella is a compact bone
- The joints in the skull are fixed (immovable joints)
- Unguligrade locomotion is walking on the toenails or hoofs
- Flexion means increasing the angle between two bones
- The joint between the axis and the atlas is a hinge joint
- The articular surface of a joint is covered with spongy bone
- Ligaments join two bones together at a joint
- Plantigrade locomotion is walking on the digits only.
- The hip joint is a hinge joint.
