chapter 9 & 10 Flashcards
This connects the acromion process to the lateral clavicle
Acroniclavicular (AC) joint
O=axillary border of scapula near inferior angle
I=crest below lesser tubercle next to latissimus dorsi attachment
A=shoulder extension, adduction, & ir
Teres major
O=spinous processe (c7-t5)
I=vertebral border between spine & inferior angle
A=scapukar retraction, elevation, & downward rotation
Rhomboid muscles
O=spinous process t7-l5 (via dorsolumbar fascia),
Posterior surface of sacrum, iliac crest &
Lower three ribs
I=medial lip of bicipital groove of humerus
A=shoulder extension, adductio , ir, & hyper extend
Latissimus dorsi
The first 30 degrees of joint is pure glenohumeral motion but after that for every 2 degrees of motion the scapula upwardly rotates 1 degree
Scapulohumeral rhythm
These allow elevation/depression, protraction/retraction, & upward/downward rotation
Sternoclavicular (SC) joints & acrominoclavicular joints
O=lateral surface of ribs 1-8
I=underneath scapula on vertebral border
A=scapular rotation & upward rotation
Serratus anterior
What is the insertion for the deltiod which is about 1/4 of thw way down the humerus?
Deltoid tuberosity
The large diamond shaped muscle which originates on the spine & has 3 subdivisions
Trapezius
The insertion of the subscapularis
Lesser tubercle
The insertion for the supraspinatus, infrapinatus, & teres minor
Greater tubercle
What is comprised of the shoukder girlde & joint
Shoulder complex
O=axillary border of scapula
I=greater tubercle of humerus
A=shoulder er, horizontal abduction
Teres minor
- Superior angle. 5. Spine
- Inferior angle. 6. Acromion process
- Vertebral border. 7. Glenoid fossa
- Axillary border. 8. Coracoid process
Landmarks of the scapula
The distal attachment
Insertion
Comprised of the scapula & clavicle
Shoulder girlde
