Bones do not:
1. provide structural framework and protection
2. provide attachment for the muscles
3. perform hemopoiesis
4. store vitamin D
The largest foramen in the human skull is:
1. | foramen magnum | 2. | jugular foramen |
3. | foramen ovale | 4. | foramen spinosum |
The bone not included in neurocranium is:
1. | frontal | 2. | ethmoid |
3. | sphenoid | 4. | zygomatic |
The clavicle articulates with:
1. first rib and thoracic vertebra
2. humerus and sternum
3. cervical rib and sternum
4. scapula and sternum
A muscle fasciculus is surrounded by:
1. | perimysium | 2. | endomysium |
3. | epimysium | 4. | hypomysium |
The extensions of the cell membrane that penetrate into the centre of skeletal and cardiac muscle cells are called as:
1. | transverse tubule system | 2. | sarcoplasmic reticulum |
3. | myofibrils | 4. | terminal cisternae |
The majority of the muscle fibers in the skeletal muscles of the leg of a long distance runner is expected to have:
1. adaptation for sudden outburst of activity
2. primarily anaerobic source of energy
3. numerous mitochondria
4. large deposits of glycogen
The synovial joint that allows maximum movements is:
1. | condyloid | 2. | gliding |
3. | saddle | 4. | ball and socket |
Even when the blood supply is inadequate, the muscle is able to sustain contraction due to:
1. | the presence of hemoglobin | 2. | glycogen storage |
3. | myoglobin | 4. | citric acid cycle |
Immediately after the motor neuron passes an impulse to a muscle fiber:
1. the impulse travels over the sarcolemma in all directions.
2. calcium is released from the sarcoplasmic reticulum.
3. cross bridge forms between the actin and myosin.
4. troponin undergoes a conformational change.
