Choose the correct statement about a muscular tissue:
Options
- ASkeletal muscle fibres are uninucleated and found in parallel bundles.
- BIntercalated discs allow the cardiac muscle cells to contract as a unit.
- CThe walls of blood vessels are made up of columnar epithelium.
- DSmooth muscles are multinucleated and involuntary.
Correct answer
B. Intercalated discs allow the cardiac muscle cells to contract as a unit.
Step-by-step solution
Skeletal muscle fibres are multinucleated and bundled in a parallel manner. Communication junction (Gap junction) in the intercalated disc of cardiac muscles allow the cardiac muscle cells to contract as a unit. Blood vessel lining contains simple squamous epithelium.
