What is the main function of the muscular system?

Which joint allows one bone to slide over another, found in the wrist and ankles?
Gliding Joint
Voluntary or Involuntary?

Involuntary - we cannot control when our heart beats; those contractions are not controllable.
Which one is a function of the Skeletal System?

A basketball player skips warm-ups and jumps right into a pick-up game. They pull a muscle and start limping around. Are they in homeostasis?

Give an example of a person who is in a state of homeostasis.
I'll read :)
Explain what a fracture, a sprain, and a dislocation are.
Fracture: a bone is broken
Sprain: ligaments have been stretched too far
Dislocation: a bone is displaced from a joint
Voluntary or Involuntary?
Smooth Muscle
It can be both! We can occasionally control our breathing (voluntary), but when we're asleep, our diaphragm makes contractions without us being consciously aware of it (involuntary).
