Week 1/2 Terms Flashcards
Type of synovial joint - Glenohumeral Joint
Ball and socket joint
Primary movements of glenohumeral joint?
Flexion/extension
abduction/adduction
internal/external rotation
Additional movements:
horizontal abduction/adduction
circumduction
Rotator cuff muscles are?
supraspinatus
infraspinatus
teres minor
subscapularis
What is a pseudo joint?
No true boney articulation.
ex; Movement of the scapula on the rib cage occurs due to the boney articulations of the sternoclavicular joint and acromiclavicular joint
Movements of the scapulothoracic joint?
elevation/depression, upward rotation/downward rotation, retraction/protraction
Name the 2 boney articulations of the traditional elbow joints?
- trochlea of the humerus articulates with the trochlear notch of the ulna
- capitulum of the humerus articulates with the head of the radius
What type of synovial joint is the traditional elbow joint?
hinge
Movements of the traditional elbow joint?
flexion/extension
Muscles that make up the elbow?
anterior:
biceps brachii
brachialis
lateral:
brachioradialis
posterior:
tricep brachii
Name the 2 articulations of the raioulnar joint?
proximal- head of the radius articulates with the radial notch of the ulna
distal- head of the ulna articulates with the ulnar notch of the radius
what type of synovial joint is the proximal radioulnar joint?
pivot
Movements of the radioulnar joint?
supination/pronation
What does extrinsic muscles of the hand do?
provides strength of the hand
What odes the intrinsic muscles of the hand do?
provides fine, precise control of the hand?
Name the articulation of the wrist joint?
distal end of the radius articulates with the scaphoid and lunate
what type of synovial joint is the wrist joint?
condyloid
What movements occur at the wrist?
flexion/extension
radial deviation (abduction)/ulnar deviation (adduction)
circumduction
Elbow is the summation of which 3 arrticulations?
1) humeroulnar joint
2) humeroradial joint
3) Radioulnar joint
What is the humeroulnar joint?
hinge joint
-trochlea humerus and trochlear notch of ulna
What is the humeroradial joint?
capitulum of the humerus and the head of the radius
What is the radioulnar joint?
2 different - one is proximal and one is distal
What movements does the 3 elbow joints allow?
flexion/extension/supination/pronation
