Identify the tissue shown in the diagram and match with its characteristics and its location.
Options
- ASmooth muscles, show branching, found in the wall of the heart.
- BCardiac muscles, unbranched muscles, found in the walls of the heart.
- CStriated muscles, tapering at bothends, attached with the bones of the ribs.
- DSkeletal muscles show striations and are closely attached with the bones of the limbs.
Correct answer
D. Skeletal muscles show striations and are closely attached with the bones of the limbs.
Step-by-step solution
Skeletal muscles show alternate light and dark bands or striations and hence called striated muscles. The cells of this tissue are long, cylindrical, unbranched and multinucleate (having many nuclei). Smooth or involuntary muscles are unstriated muscles. The cells are long with pointed ends (spindleshaped) and uninucleate (having a single nucleus). Cardiac muscles or Heart muscle cells are cylindrical, branched and uninucleate. They are involuntary in nature.
Related Theory Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.
