22/42

Origin: External occipital protuberance,

nuchal ligament, superior nuchal line,spinous process

Insertion: Posterior-lateral 3rd of clavicle,acromion process, spine of scapula

3 fiber directions: Ascending, descending,transverse

Innervation:Accessory nerve,Cervical spinal

nerves (C3-4)


23/42

Origin: Ribs 3-5

Insertion: Coracoid process

Innervation: Medial

pectoral nerve (Branch ofbrachial plexus) (C8-T1)


24/42

Origin: Anterior surface of the top 8-9ribs, along about the mid-clavicular line

Insertion: Medial boarder of the scapula(costal / anterior surface)

Lower 4 interdigitate with the externaloblique muscle

Abducts scapula upwards like thetrapezius muscle

Innervation: Long thoracic nerve (fromthe roots of C5-7)


25/42

2 Components: Clavicular head,Sternocostal head

Origin:(clavicular) Anterior serface ofmedial half of the clavicle

(sternocostal) Anterior surface ofthe sternum, anterior surface ofthe costal cartilages (2nd-6th),aponeurosis of the externaloblique

Insertion: intertubercular grooveof the humerus

Innervation: Lateral and medial pectoral nerves (branches of brachial plexus)(Clavicular) C5-6

(Sternocostal) C7-8,T1


26/42

Origin: Posterior portion of theiliac crest, Spinous process ofvertebrates T7-L5, lower 3-4 ribs,thoracolumbar aponeurosis(down to the sacrum)

Insertion: Intertubercular Groove

Innervation: Thoracodorsal nerve


27/42

3 Components: Anterior, Lateral,

Posterior

Origin:(Anterior) Anterior lateral 3rd of theclavicle(Lateral) Acromion

(Posterior) Spine of the scapula

Insertion:(All 3 components) Deltoid tuberosity

Innervation: Axillary nerve


28/42

2 Heads: Long Head (Lateral side),Short Head (Medial side)

Origin:(Long) Supraglenoid tuberosity(Short) Coracoid Process

Insertion:Radial tuberosity (both heads)Bicipital aponeurosis going intodeep fascia of forearm (bothheads)

Innervation: Musculocutaneousnerve (C5-C6)

**important in supination of theforearm**


29/42

3 Heads:

(Superficial Plane) Long Head, Lateral Head(Deep Plane) Medial Head

Origin:(Long) Infraglenoid Tubercle(Lateral) Superior to radial groove

(Medial) Inferior to radial groove

Insertion: Olecranon process of the ulna

Innervation: Radial Nerve, Axillary Nerve
