Clavi-pectoral Fascia & serratus anterior muscle

This presentation shows the Anatomy of Clavi-pectoral Fascia & serratus anterior muscle

Transcript

1. Clavi-pectoral Fascia
2. Pectoralis minor Clavipectoral fascia Suspensor ligament of axilla Subclavius m. Dr. Sherif Fahmy Subclavius m. Pectoralis minor m. Contents of axilla Clavi-pectoral fascia is present Clavi-pectoral fascia is removed
3. Coracoid process Coraco-clavicular ligament Upper 2 costal cartilage Clavipectoral fascia Medial & lateral extensions of clavi-pectoral fascia Pectoralis minor m. Dr. Sherif Fahmy
4. Attachments of Clavi-pectoral Fascia Upper: to clavicle at margins of groove of subclavius Medial: to upper 2 costal cartilages Lateral: to coracoid process and coraco-clavicular ligament Lower: It encloses pectoralis minor muscle, then continues to floor of axilla as suspensory ligament of axilla
5. Cephalic vein Acromio-thoracic art. & lateral pectoral nerve Structures that pass through clavipectoral fascia
6. L.S. of anterior wall of axilla Clavicle Subclavius m. Clavi-pectoral fascia Pectoralis minor with fascial sheath Suspensory lig. of axilla Floor of axilla Pectoralis major m. Pectoral fascia Dr. Sherif Fahmy
7. Serratus Anterior Muscle (page 57)
8. Anterior Posterior Serratus Anterior Muscle Pectoralis major m. External abdominal oblique m.
9. Serratus anterior muscle
10. Serratus anterior m.
11. Origin of Serratus Anterior Muscle
12. Origin of serratus anterior muscle Costo-chondral junctions
13. 1st digitation of serratus anterior m. First rib Second rib Tendinous arch
14. Serratus Anterior m. External abdominal oblique m.
15. Attachments of Serratus Anterior M. Origin: -By 8 digitations from outer surface of upper 8 ribs (midway between costo-chondral junctions and angle of ribs). -First digitation arises from 1st & 2nd ribs with tendinous arch inbetween, the other digitations each arises from the rib of the same number. -Lower part interdigitate with upper part of external abdominal oblique muscle. Insertion: -Anterior aspect of medial border of scapula.
16. 1st digitation 2nd & 3rd digitations Lower 5 digitations Digitations of Serratus Anterior Muscle
17. Insertion of Serratus Anterior Muscle
18. Medial border Superior angle Inferior angle
19. 1st digitation 2nd digitation 3rd digitation Lower 5 digitation Superior angle Medial border Inferior angle Insertion
20. Serratus anterior muscle Long thoracic nerve Nerve Supply
21. Action of Serratus Anterior M. 1- Powerful protraction of scapula (pushing & reaching). 2- Lower 5 digitations upwards rotates the scapula (abduction of arm above 90 degrees). 3- Fix the scapula over chest specially during movement of the scapula. 4- Raise the ribs in forced inspiration.
22. Paralysis of Serratus Anterior Muscle
