Choose the correct statement about a muscular tissue:

Choose the correct statement about a muscular tissue:
  1. Skeletal muscle fibres are uninucleated and found in parallel bundles.
  2. Intercalated discs allow the cardiac muscle cells to contract as a unit.
  3. The walls of blood vessels are made up of columnar epithelium.
  4. Smooth muscles are multinucleated and involuntary.

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.
