Almost all mammals have seven
1. | cervical vertebrae | 2. | carpal bones |
3. | cranial bones | 4. | sacral vertebrae |
The head of the humerus forms a ball and socket joint with a scapular:
1. | acromion process. | 2. | glenoid cavity. |
3. | coracoid process. | 4. | acetabulum. |
The clavicle articulates with:
1. first rib and thoracic vertebra
2. humerus and sternum
3. cervical rib and sternum
4. scapula and sternum
There are 8 and 7 bones respectively in:
1. | tarsal [ankle] and carpal [wrist] |
2. | carpal[wrist] and tarsal[ankle] |
3. | neurocranium and facial skeleton |
4. | facial skeleton and neurocranium |
Identify the correct characteristic of a skeletal muscle:
1. spindle-shaped cells
2. involuntary control
3. true syncytium
4. non striated
A muscle fasciculus is surrounded by:
1. | perimysium | 2. | endomysium |
3. | epimysium | 4. | hypomysium |
Arrange the given structures in relation to a skeletal muscle in descending order of their size:
a. whole muscle
b. muscle fiber (cell)
c. myofilament
d. myofibril
e. muscle fasciculus
1. | a, b, e, c, d | 2. | a, b, e, d, c |
3. | a, e, b, c, d | 4. | a, e, b, d, c |
The correct statement regarding myofibril would be:
1. | It is the name for a muscle cell. |
2. | It contains sarcoplasmic reticulum. |
3. | It is made up of many sarcomeres. |
4. | It is a bundle of muscle cells. |
Myosin myofilaments are
1. made up of thick and thin myofilaments.
2. found only in the H zone.
3. not seen in the H zone.
4. attached to filaments that form the M line.
Identify the correct statement:
1. Tropomyosin is found in two forms – monomeric G and polymeric F.
2. The head of the myosin molecule binds to an active site on G actin.
3. ATPase is present in troponin A.
4. Actin molecules do not move during muscle contraction.
