Skeletal muscles are:
1. | Striated, Multinucleate and Voluntary |
2. | Non-Striated, Multinucleate and Voluntary |
3. | Striated, Multinucleate and Involuntary |
4. | Non-Striated, Uni-nucleate and Voluntary |
The smallest, functional unit of contraction is the:
1. | muscle fiber | 2. | sarcomere |
3. | myofilament | 4. | myofibril |
A motor neuron along with all the muscle fibers innervated by it constitute a:
1. | Fascicle | 2. | Motor end plate |
3. | Motor unit | 4. | Myoneural junction |
What type of muscles do you expect to find in the inner walls of hollow visceral organs?
1. | Involuntary, nonstriated | 2. | Voluntary, nonstriated |
3. | Involuntary, striated | 4. | Voluntary, striated |
A muscle cell is called as a:
1. | sarcomere | 2. | fiber |
3. | myofibril | 4. | myofilament |
I: | is derived from embryonic endoderm |
II: | constitutes about 40-50 percent of human body |
Regarding a skeletal muscle fibre:
I: | It is a syncytium. |
II: | It has sarcoplasmic reticulum [a type of smooth ER] that stores calcium. |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
