Striations

skeletal muscle is striated; its long, thin, multi-nucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle its striated appearance

Multiple Choice

Which types of muscle fibers are striated?

• Smooth and Cardiac

• Cardiac and Skeletal

• Smooth and Skeletal

How do they help us move?

Skeletal muscles are attached to bones by tendons, and they produce all the movements of body.

Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control.

We can control them conciously!

Multiple Choice

What attaches muscle to bone?

• Ligaments

• Tendons

Cardiac and Smooth Muscle

Both Cardiac and Smooth Muscles are involuntarily controlled, meaning we have no conscious control over the movement of these muscles!

IMAGINE THAT!

Imagine that if we had to consciously control our cardiac muscle to circulate our blood through our bodies!
