Week Two OIA Upper E Flashcards
Origin of supraspinatus
Supraspinous fossa of scapula
Insertion of supraspinatus
greater tubercle of the humerus
Supra = greater rubercle
Action of supraspinatus
Shoulder abduction and stabilization
Abduction to stabilization
Origin of infraspinatus
infraspinatus fossa of scapula
Insertion of infraspinatus
greater tubercle of the humerus
Action of infraspinatus
shoulder laterally rotation, adduction, stabilization
Adds lateral rotation
Origin of Teres Minor
Upper 2/3 of the lateral edge of the scapula
2/3 of the lateral edge of the scap
Insertion of Teres Minor
Head of the humerus, greater tubercle of the humerus
Greater head
Action of Teres Minor
shoulder laterally rotation, adduction, and stabilization
Adds lateral rotation
Origin of subscapularis
Subscapular fossa of scapula
Insertion of subscapularis
lesser tubercle of humerus
Sub is lesser
Action of subscapularis
Shoulder medial rotation and stabilization
mediocer
Origin of Rhomboids Major
The spinous process of T2-T5
2-5 spines
Insertion of rhomboids major
lower portion of the medial border of the scapula
Major: lower and medial to the scap
Action of rhomboids major
scapula: adduction, elevation, downward rotation
Add elevation to go down rotations
Origin of rhomboids minor
The spinous process of C7-T1
c7-t1 spines
Minor = minues (7-1)
Insertion of rhomboids minor
upper portion of the medial border of the scapula
Minor = upper and medial to scap
Action of rhomboids minor
Scapula: adduction, elevation, and downward rotation
Same is major
Origin of levator scapula
Transverse processes of C1-C4
1-4 of the transverse
Insertion of levator scapula
The upper portion of the medial portion of the scapula
Upper and medial to scap
Same as rhomboids minor
Action of levator scapula
Extension of head/neck, scapula elevation, downward rotation, neck lateral flexion, and rotation
downward elevation of scap, neck F and E, head extension
Origin of serratus Anterior
The external surface of first 8-9 ribs
8-9 external ribs
Insertion of serratus Anterior
The anterior surface medial border of scapula
Anterior and medial to scap
Serratus anterior = anterior surface
Action of serratus anterior
scapula abduction, and depression, upward rotation, holds scapula to ribs
depression is upward to abduction
Ab-D-U (AB Duuu)
Origin of pec major
Sternum, cartilage of ribs 1-6, anterior 1/2 of clavicle.
1/2 of clavicle, 1-6 of the ribs cartilage on the sternum
Insertion of pec major
Crest of the greater tubercle of the humerus
Major = greater tubercle
Action of pec major
Adduction, medial rotation, flexion, horizontal adduction, extension of shoulder, assist in forced inhalation
Add and horizontal adduction, medial rotation to extend shoulder
Origin of pec minor
3-5 ribs, adjacent to the costochondral junction
3-5 ribs, adj to costco junction
Insertion of pec minor
coracoid process of scapula
coracoid is minor to scap
Action of pec minor
depression, abduction, anterior tilt, downward rotation, assist in forced inhalation
antererir tilt, Abduction, depression, downward rotation
(AADD)
Origin of subclavius
1st rib and cartilage
1 rib
Insertion of subclavius
inferior surface of middle 1/3 of clavicle
inferior 1/3 of clavicle
Action of subclavius
clavicle depression and elevation of 1st rib
depressed clavicle and elevated 1 rib
Origin of coracobrachialis
coracoid process of scapula
Cora = coracoid
Insertion of coracobrachialis
medial/mid shaft of humerus, anterior
MM of shaft to anterior
Action of coracobrachialis
shoulder flextion and adduction
Add flextion
