MOINA ( SHOULDER, CHEST, RIBS) -DRIEEEEEEEEE

Deltoid

O: Lateral third of the clavicle, acromion, spine of scapula; I:Middle of Lateral shaft humerus; A: Abduction of the arm.

Supraspinatus

O: Supraspinous fossa of scapula ; I:Greater tuberosity of Humerus, Capsule of shoulder joint; A: Abducts arm and stabilizes shoulder joint.

Infraspinatus

O: Infraspinous fossa of scapula ; I:Greater tuberosity of Humerus, Capsule of shoulder joint; A: Laterally rotates arm and stabilizes shoulder joint.

Teres Major

O: Lower third of lateral border of scapula; I: Medial Lip of bicipital groove of humerus; A: Medially rotates arm and adducts arm and stabilizes shoulder joint.

Teres Minor

O: Upper two third of lateral border of scapula; I: Greater Tuberosity of humerus; A: Laterally rotates arm and stabilizes shoulder joint.

Subscapularis

O: Subscapular fossa; I: Lesser tuberosity of humerus, capsule of shoulder joint; A: Medially rotates arm and stabilizes shoulder joint.

Pectoralis Major

O: Clavicle, Sternum and upper 6 costal cartilages; I: Lateral lip of bicipital groove of humerus; A: adducts arm and rotates it medially also helps flex arm

Pectoralis Minor

O: Third Fourth Fifth Ribs; I: Coracoid Process of scapula; A: Depresses point of shoulder; if the scapula is fixed, it elevates the ribs to origin

Subclavius

O: First costal cartilage; I: Clavicle; A: Depresses the clavicle and steadies this bone during movements of the shoulder girdle.

Serratus Ant.

O: Upper eight ribs ; I: Medial border and inferior angle of scapula ; A: Depresses the clavicle and steadies this bone during movements of the shoulder girdle

External Intercostal Muscles

O: Inferior border of rib; I: Superior border of the rib below; A: Stabilize the rib cage: With first rib fixed, they raise ribs during inspiration and thus increase anteroposterior and transverse diameters of thorax

Internal Intercostal Muscles

O: Inferior border of rib; I: Superior border of the rib below; A: Stabilize the rib cage: With last rib fixed by abdominal muscles, they lower ribs during expiration

Innermost Intercostal Muscles

O: Adjacent ribs; I: Adjacent ribs; A: Assists external and internal intercostal mm

Diaphragm

O: Xiphoid process, lower six costal cartilages, first 3 lumbar vertebrae; I: Central tendon; A: Increases vertical diameter of thorax by pulling central tendon downward

Levatores costarum

O: tip of transverse process; I: Rib below ; A: Elevates ribs, possibly proprioception

Serratus posterior superior

O: Lower cervical and upper thoracic spines; I: Upper ribs ; A: Proprioception

Serratus posterior inferior

O: Upper lumbar and lower thoracic spines; I: Lower ribs ; A: Proprioception
