Hint: All striated muscles are bound to some part of the body. Striated muscle fibres also have cylindrical shape with blunt ends while smooth muscle fibres can be defined as spindle-like with tapered ends.
Complete Answer:
- Striated muscle tissue is a muscle tissue with functioning units of sarcomeres that are replicated. The involvement of sarcomeres occurs as a set of visible bands around the muscle fibres, and is liable for the striated nature of this tissue.
- Striated muscle tissue has the primary function of creating tension to contract. These contractions would either pump blood around the body (heart muscle) or induce respiration, mobility or posture.
There are two groups of muscles with striations:
1) Cardiac (heart muscle) muscle;
2) Skeletal muscle (a skeletal muscle)
Now, let us find the solution from the option.
- Striated muscle plays a significant role in forming the body's structural structure.
- It is the only muscle tissue which is under the direct conscious influence of the brain's cerebral cortex, and is also the voluntary muscle.
- Striated muscle tissue comprises T-tubules that cause calcium ions to be released from the sarcoplasmic reticulum.
Thus, the correct option is (C) i.e. Leg muscles.
Note: Microscopically, because of their closely bound myofibrils, both the skeletal and cardiac musculature has a "striated" look.
