Joints Flashcards
define joint: and function
articulation/ arthrosis
- point of contact between two bones, bone/cartilage, bone/tooth
hold bones together allowing movement/ flexibility
increase of mobility =
decrease in stability and vice verca
classification: no movement
synarthrosis
classification: slight movement
amphiarthrosis
classification: free movement
diarthrosis
movements: extension and eg.
SAGITTAL PLANE: increasing angle in joint, eg. knee -> straight limb
movements: flexion and eg.
SAGITTAL PLANE: decreasing angle of joint, eg shoulder joint -> flat to side
movements: hyperextension and eg.
SAGITTAL PLANE: extension of body part more than normal range, eg. tilting head towards posterior
body movements: head
extension, flexion, hyperextension
body movements: shoulder joint (sagittal p)
flexion, extension, hyperextension
body movements: elbow joint (sagittal p)
flexion, extension
body movements: wrist joint (sagittal p)
flexion, extension, hyperextension
body movements: hip joint (sagittal p)
flexion, extension, hyperextension
body movements: knee joint (sagittal p)
flexion, extension
body movements: intervertebral joints (sagittal p)
lateral flexion
movements: abduction
CORONAL PLANE:
movement away from midline, eg. arm straight with shoulder
movements: adduction
CORONAL PLANE: towards the midline/body, eg. wrist bending fingers towards body
body movements: shoulder joint (coronal p)
abduction, adduction
body movements: wrist joint (coronal p)
abduction, adduction
body movements: hip joint (coronal p)
adduction, abduction
body movements: metacarpophalangeal joints (excl. thumb)
abduction, adduction
body movement: atlanto-axial joint rotation
left right (no)
body movement: shoulder joint rotation
lateral (away from body), medial (towards body) with arm bent at the elbow
