What is appendicular skeleton?
A place where two or more bones meet to connect parts and allow for movement in the body.
What is articulation?
A freely movable synovial joint.
What is diarthrosis?

What is agonist?
Voluntary muscle
What is Skeletal Muscle?
The axis of the body; consists of the head, vertebral column, rubs, and sternum.
What is axial skeleton?
Joint that allows movement in three planes around a central point.
What is ball-and-socket joint?
A limited-movement, nonsynovial joint.
What is synarthrosis?
A muscle usually located on the opposite side of a joint from the agonist and having the opposite action.
What is antagonist?
Increasing angle at a joint movment
What is extension?
A tough, flexible connective tissue with a high water content that makes it softer than bone.
What is cartilage?
Joint that allows flexion and extension in one plane, changing the angle of the bones at the joint.
What is hinge joint?

What is amphiarthrotic?
Muscles that work together to create a movement

Decreasing angle at a joint movement.
What is flexion?

What is compact bone?
Example of a sesamoid bone
What is patella?

Quality of skeletal muscle tissue
Striated,
Bundles,
Covered in Fascia etc.
Movement away from the midline.
What is abduction?
The lighter-weight portion of the bone, which is made up of trabeculae.
What is spongy bone?
Covering tissue of complex joints
What is synovium?
A synarthrotic joint in which two bony compartments are joined directly by a thin layer of dense fibrous tissue. Hint :skull
What is suture?
Point of attachment closest to movement.
