Question

In which muscle stripes are absent

Answer 1

Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.

Answer 2

Smooth muscle has an absence of striation or banding. Strength is not needed for the involuntary actions of the digestive system or associated organs. Cardiac muscle cells are striated (for strength), multi-nucleated (for additional control) and branched (for added strength).
