Q. No.Which of the following joints would allow no movement?
1. Fibrous joint
2. Cartilaginous joint
3. Synovial joint
4. Ball and socket joint
Which of the following is not a function of the skeletal system?
1. Production of erythrocytes
2. Storage of minerals
3. Production of body heat
4. Locomotion
Sliding filament theory can be best explained as:
| 1. | when myofilaments slide past each other, actin filaments shorten while myosin filament does not shorten |
| 2. | actin and myosin filaments shorten and slide past each other |
| 3. | actin and myosin filaments do not shorten but rather slide pass each other |
| 4. | when myofilaments slide past each other, myosin filaments shorten while actin filaments do not shorten |
Glenoid cavity articulates:
| 1. | clavicle with acromion | 2. | scapula with acromion |
| 3. | clavicle with scapula | 4. | humerus with scapula |
Select the correct matching of the types of the joint with the example in the human skeletal system:
| Types of joint | Examples | |
| 1. | Cartilaginous joint | between frontal and parietal |
| 2. | Pivot joint | between third and fourth cervical vertebrae |
| 3. | Hinge joint | between the humerus and pectoral girdle |
| 4. | Gliding joint | between carpals |
1. 1
2. 2
3. 3
4. 4
Stimulation of a muscle fiber by a motor neuron occurs at:
1. the neuromuscular junction
2. the transverse tubules
3. the myofibril
4. the sarcoplasmic reticulum
The characteristics and an example of a synovial joint in humans are:
| Characteristics | Examples | |
| 1. | Fluid-filled between two joints, provides cushion | Skull Bones |
| 2. | Lymph filled between two bones, limited motion | Gliding joint between carpals |
| 3. | Fluid-filled synovial cavity between two bones | Joint between atlas and axis |
| 4. | Fluid cartilage between two bones, limited motion | Knee joint |
Select the correct statement with respect to locomotion in humans:
| 1. | Accumulation of uric crystals in joints causes inflammation |
| 2. | The vertebral column has 10 thoracic vertebrae |
| 3. | The joint between adjacent vertebrae is a fibrous joint |
| 4. | The decreased level of progesterone causes osteoporosis in old people |
The H-zone in the skeletal muscle fibre is due to:
| 1. | The central gap between myosin filaments in the A-band. |
| 2. | The central gap between actin filaments extends through myosin filaments in the A-band. |
| 3. | Extension of myosin filaments in the central portion of the A-band |
| 4. | The absence of myofibrils in the central portion of the A-band. |
1. Sarcomere does not shorten
2. A band remains the same
3. A, H and I bands shorten
4. Actin filaments shorten
