The main function of skeletal muscles

Movment

100

These muscles are only found in this area of the body

Heart

100

Smooth muscles can be found here

Visceral organs

200

Unlike cardiac and smooth muscle, this type of muscle requires this specialized junction to initiate contraction.

Neuromuscular junction (NMJ)

200

Cardiac muscle cells are branched, striated, and contain this number of nuclei.

One (uninucleate)

200

This protein found in the smooth muscles is a binding site for calcium

Calmodulin

300

This type of junction is not found in skeletal muscle.

Gap junction

300

Cardiac muscle relies almost exclusively on this type of metabolism.

Aerobic metabolism

300

Smooth muscles contract at this speed.

Slow

400

These descriptive words describe the shape and appearance of skeletal muscles.

Long, cylindrical, striated, and contain multiple nuclei.

400

Cardiac cells are connected by these structures, which include gap junctions.

Intercalated discs

400

Unlike skeletal and cardiac muscle cells, smooth muscle cells lack this structure, giving them their non-sriated shape.

Organized myofibrils

500
The 4 function of skeletal muscles are 

Movment

Maintain Posture

Stabilize Joints

Gerate Heat

500

While both cardiac and skeletal muscle have striations, only this one contracts without direct nerve stimulation due to these cells.

Pacemaker cells

500

Borrowed from the New Latin phrase, meaning "spindle of obscure origin", this word describes the shape of smooth muscle cells
