Function is to produce movement

Three types Skeletal muscle

Cardiac muscle

Smooth muscle

Muscle Tissue TypesMuscle Tissue Types



Skeletal muscle Can be controlled

voluntarily

Cells attach to connective tissue to bones

Cells are striated

Cells have more than one nucleus Figure 3.19b

Skeletal MuscleSkeletal Muscle




Cardiac muscle Found only in the

heart

Function is to pump blood (involuntary)

Cells attached to other cardiac muscle cells at intercalated disks

Cells are striated

One nucleus per cell Figure 3.19c

Cardiac MuscleCardiac Muscle




Smooth muscle Involuntary muscle

Surrounds hollow organs

Attached to other smooth muscle cells

No visible striations

One nucleus per cell Figure 3.19a
