MUSCLE TISSUE
Muscle Tissue Characteristics• Contractile• Made of contractile proteins• Cells are called fibers
Skeletal Muscle• 40% of body weight• Under voluntary control; attached to skeleton• Striated, or banded, appearance• Cells have multiple nuclei
Smooth Muscle Characteristics• Not under voluntary control• Found in walls of hollow organs, skin,
and eyes• Tapered and have no striations
Cardiac Muscle Characteristics• Muscle of the heart• It is not under voluntary control• Striated• Connected to each other via intercalated discs
