Joint and Movement
These are three functional classifications of joints based on movement.
What are synarthroses, amphiarthroses, and diarthrosis?
The main function of the muscular system is this.
What is movement?
What is contract?
Elevation and depression refer to this type of motion.
What is lifting and lowering a body part?
A break in a bone is called this.
What is a fracture?
These are the three structural classifications of joints.
What are fibrous, cartilaginous, and synovial joints?
These are the three classifications of muscles based on how they work during movement.
What are prime movers (agonists), antagonists, and synergists?
The smallest contractile unit of a muscle fiber is called this.
What is a sarcomere?
The movement that turns the foot toward or away from the midline is called this.
What are inversion and eversion?
The process of bone tissues formation is called this.
What is ossification?
This joint allows the greatest range of motion.
What is the shoulder joint?
These are the three types of muscle tissue.
What are skeletal, cardiac, and smooth muscle?
This neurotransmitter is used by motor neurons to trigger muscle contractions.
What is acetylcholine?
The movement of making circles with your arm is called this.
What is circumduction?
The patella is an example of this type of bone.
What is a sesamoid bone?
These SIX configurations describe the shapes and motions of synovial joints.
What are gliding, hinge, pivot, condylar, saddle, and ball in socket joints?
These are the jobs of three classifications of muscles: agonists, antagonists, and synergists.
What are: agonists produce movement, antagonists oppose movement, and synergists help prime movers?
These three connective tissues wrap different parts of a muscle.
What are the epimysium (entire muscle), perimysium (fascicle), and endomysium (muscle fiber)?
Turning the palm upward/anteriorly is called this motion.
What is supination?
The ribs are classified as this type of bone.
What are flat bones?
This immovable cartilaginous joint connects the sternum and the first rib.
What is synchondrosis?
These muscles act as synergists by immobilizing the origin bone to make the primer mover more effective.
What are the fixators?
When the effort is farther from the fulcrum than the load, the lever has this.
What is a mechanical advantage?
The fibrous joints that anchor your teeth into the gums are called this.
What are gomphoses?
The axial skeleton contains 80 bones while the appendicular skeleton contains this many.
What is 126 bones?
