internal organs and systems are called smooth muscles.

Cardiac - controls the contractions of the heart.Also an involuntary muscle

Voluntary - muscles can be contracted at will.Also called skeletal muscles

Most of your muscle tissue is skeletal, and almost all _________________ are under voluntary control.

Tendons – anchor muscles to boneBursas – lie between some tendons

and the bones beneath them. Bursas are lined with synovial fluid – making it easier for the tendon to slide over a bone when the tendon shortens
