Synovial Joints
This type of synovial joint is also known as a plane joint.
Gliding
Moving limb in a circle, like making circles with arms.
Circumduction
the meeting places between 2 or more bones. They give the skeleton mobility and hold it together.
Joints
_______________ are non-moving joints
Ex. The part of the skull that protects the brain: cranium
Synarthroses
____________________ are connect bones with cartilage. Can be rigid but also slightly movable.
Cartilaginous joints
Allows angular movements like flexion and extension.
Hinge
Lifting (then lowering) a body part superiorly, Like shrugging your shoulders, jaw dropping.
Elevation and depression
Important connective tissues:
_____________ attach bones to bones
_____________ attach muscles to bones
Ligaments
Tendons
____________ are freely moving joints
Ex. Like knee and elbow joints, mainly in our limbs
Diarthroses
_______________ connect bones with dense connective tissues AND a fluid filled joint cavity.
Synovial joints
Allows rotation as well as twisting movements back and forth.
Pivot
Sticking jaw out (to make an under bite) and back in
Protraction and retraction
Movement occurs when muscles contract. The two types of movements are:
_____________ causes a change in the length of the muscles Ex. Lifting a box or doing push-ups
_____________ is no change in length
Ex. Standing with good posture or doing a plank
Isotonic
Isometric
________________ are slightly-moving joints
Ex. Where pubic bones meet in the pelvis.
Amphiarthroses
_______________ connect bones with the collagen fibers of dense connective tissue. Mostly immovable.
Fibrous Joints
Allows opposition movements as well as flexion/extension, abduction/adduction.
Ex. Thumb joints
Saddle
Turning the foot towards the midline of the body vs. turning away from the midline of the body.
Inversion and eversion
The less movable the joint is the _______________ stable it is.
more
Bones in the skull are held together with fibrous joints called __________.
sutures
Allows movements like flexion/extension, as well as abduction and adduction.
Condylar
Lifting foot up and down at the ankle.
Dorsiflexion and plantar flexion
_____________ is the movable bone during a muscle contraction.
_____________ the bone that moves less or not at all.
Insertion
Origin
A slightly movable joint made of fibrocartilaginous intervertebral discs that act as a shock absorbers between vertebrae is called a ______________.
symphysis
