Three Muscle Tissue Types
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Muscle tissue takes three forms: smooth muscle is involuntary and unstriated, skeletal muscle is voluntary and striated with many nuclei, and cardiac muscle is involuntary, striated, and single-nucleated.
Show
Cardiac muscle cells link through intercalated discs that pass an electrical impulse quickly from cell to cell.
Watch for
Cardiac muscle is not under conscious control even though it shares skeletal muscle's striated appearance.
