Muscle Song

(to the tune of Twinkle Twinkle Little Star)

Muscles, Muscles in our body
so vital to our function
everywhere in our body
what would we do without you
Muscles, Muscles in our body

So many different types
cardiac smooth and skeletal
all in different areas
serving different functions
Muscles, Muscles in our body

Cardiac muscles in the heart
under involuntary control.
they appear to be striated
in the walls of the heart.
helping the heart beat everyday

Smooth muscles, in visceral organs
under involuntary control.
They appear spindle shaped,
contracting and relaxing,
working all over in the body.

Skeletal muscles, attached to bones
under voluntary control.
They appear to be striated,
stretching across bones and joints.
working with bones to give you movement

All these muscles are so useful
but how do they function?
myosin moving along filament
results in muscle contraction and release.
And that's the sliding filament theory.

Muscles, Muscles in our body
so vital to our function
everywhere in our body
what would we do without you
Muscles, Muscles in our body
