Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. They comprise 30 to 40% of our total body mass. These muscles connect to your bones and allow us to perform a wide range of movements and functions.
Smooth muscle cells are spindle-shaped, have a single, centrally located nucleus, and lack striations. These muscles are found all over the body, performing several vital functions of the body, and controlled by the nervous system.
Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. It differs from skeletal muscle in that it exhibits rhythmic contractions and is not under voluntary control.
