The cancellous bone beneath the articular cartilage in a synovial joint:
1. provides a smooth surface for articulating
2. absorbs shocks and helps protect the joint
3. holds together the bones of the synovial joint
4. secretes synovial fluid
The synovial joint that allows maximum movements is:
1. | condyloid | 2. | gliding |
3. | saddle | 4. | ball and socket |
The joint that is weak inferiorly and is most likely to be dislocated is:
1. knee joint
2. hip joint
3. shoulder joint
4. elbow
The proximal radio-ulnar joint is a:
1. pivot joint
2. gliding joint
3. ball-and-socket joint
4. condyloid joint
The joint that will exhibit maximum mobility amongst the following would be:
1. between carpal bone
2. radio-ulnar
3. between acetabulum and femur
4. atlanto-axial
The part of the sarcomere that is composed of only myosin myofilaments is:
1. | A band | 2. | I band |
3. | M line | 4. | H zone |
Identify the most abundant of the muscle proteins:

Muscles get their energy directly from:
1. glucose
2. ATP
3. creatine phosphate
4. creatinine
Muscles store excess glucose as:
