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.
