Pronation or suppination

Attatches acromion process to the clavicle

Acromioclavicular ligament

Inversion (foot moves medially) eversion (lateral)

Foot

Bones separated by pad of fibrocartilage

Symphysis

Permits movement along two axis forward/backward and left/right.

Biaxial

Attatches humerus to glenoid cavity/fossa.

Glenohumeral ligament

Movement at an angle

Angular motion

Slightly movable joints

amphiarthrosis

Attaches coracoid process to the acromial process

coracoacromial ligament

Moves structure inferiorly, open mouth

depression

When "nucleolus pulposes" (inner layer of disk) breaks through "annulus fibroses"

Herniated disk

Arm moves lateral, medial

Lateral or medial rotation

Immovable joints

Synarthrosis

Permits movement along 3 axis forward/backward and left/right and rotation.

Triaxial

Spint or twist

Rotation

(Moves toes upward) and plantar flexion (move toes downward)

Dorisflexion

(Bind bone to bone) around outside of joint for strenth; sprain ligaments are stretched

Ligaments

Function is shock absorption

Synovial fluid

Provides nutrients and waste disposal for "chondrocytes"

Synovial fluid

Bones connected by ligaments

Syndesmosis

Adipose tissue that act as packing material that fills space as joint moves (near point)

Fat pad

Bends vertebrae to one side

Lateral flexion

When "anulus fibrosis" Outer layer of disk, is forced out from between vertebrae

Slipped disk

When "nucleolus pulposes" (inner layer of disk) breaks through "annulus fibroses"

Herniated disk

When "anulus fibrosis" Outer layer of disk, is forced out from between vertebrae

Slipped disk

____________ is a joint or where two bones come together?

Arrticulations
