1. UPPER EXTREMITY BONES , MUSCLES
DR.VINIT.K.ASHOK
ADJUNCT FACULTY

2. BONES FORM PART OF THE APPENDICULAR SKELETON
ARE ATTCHED TO THE TRUNK VIA THE PECTORAL GIRDLE( CLAVICLE , SCAPULA). SHOULDER JOINT ( UNSTABLE, GREATER RANGE OF MOVEMENT)
BONES
UPPER ARM- HUMERUS
FOREARM – RADIUS/ULNA
WRIST – CARPAL BONES
PALM –METACARPALS
FINGERS- PHALANGES
* STUDY IN DETAIL FROM THE BOOK AND IN THE LAB

3. MUSCLES ANY MUSCLE THAT CROSSES A JOINT ACTS ON THAT JOINT
ORIGIN IS THE MORE FIXED ATTACHMENT
INSERTION IS MOVED TOWRDS THE ORIGIN
MUSCLES CROSSING THE SHOULDER JOINT( ACT ON THE JOINT AND ALSO MOVE THE UPPER ARM ( HUMERUS)
PRIME MOVERS ( LARGEST)- PECTORALIS MAJOR,LATISSIMUS DORSI,DELTOID
ROTATOR CUFF MUSCLES- SUPRASPINATUS, INFRASPINATUS SUBSCAPULARIS AND TERES MINOR
TERES MAJOR AND CORACOBRACHIALIS
TABLE 11.9
MUSCLES ANTERIOR-FLEXION ARM
MUSCLES POSTERIOR- EXTENSION OF ARM
ABDUCTORS- MIDDLE FIBRES OF DELTOID
ADDUCTORS P.MAJOR,LATISSIMUS DORSI
* STUDY THE NERVE SUPPLY

5. ANTERIOR SHOULDER MUSCLES

6. POSTERIOR SHOULDER

7. MUSCLES CROSSING THE ELBOW JOINT
ANTERIOR ---FLEXORS) FOREARM
POSTERIOR-EXTENSORS
1. ANTERIOR- BICEPS, BRACHIALIS, BRACHIORADIALIS
2. POSTERIOR-TRICEPS
* biceps brachii also supinates the forearm
* BICEPS AND BRACIALIS MUSCULOCUTANEOUS NERVE
TRICEPS AND BRACHIORADIALIS RADIAL NERVE

8. MUSCLES CROSSING SHOULDER AND ELBOW JOINT

9. MUSCLES OF FOREARM
CAUSE MOVEMENT OF THE WRIST , HAND AND FINGERS, SUPINATION AND PRONATION OF THE FOREARM
ANTERIOR – FLEXORS
POSTERIOR-EXTENSORS
PRONATORS( ANT COMPARTMENT) PRONATOR TERES, PRONATOR QUADARTUS
SUPINATORS-( POSTERIOR COMPARTMENT) SUPINATOR MUSCLE
MOST FLEXORS ARISE FROM THE MEDIAL EPICONDYLE
MOST OF THE EXTENSORS ARISE FROM THE LATERAL EPICONDYLE
AT THE WRIST THE FOREARM MUSCLES PRODUCE FLEXION, EXTENSION,ADDUCTION AND ABDUCTION OF THE HAND
AT THE FINGERS THEY CAUSE ONLY FLEXION AND EXTENSION

10. MUSCLES OF THE FOREARM SUPERFICIAL AND DEEP SUPERFICIAL-
PRONATOR TERES
FLEXOR CARPI RADIALIS
PALMARIS LONGUS

FLEXOR DIGITORUM SUPERFICIALIS
* ALL ARE SUPPLIED BY THE MEDIAN NERVE EXCEPT THE FLEXOR CARPI ULNARIS ----SUPPLIED BY THE ULNAR NERVE

11. SUPERFICIAL MUSCLES FOREARM

12. DEEP MUSCLES FOREARM FLEXOR POLLICIS LONGUS- MEDIAN NERVE
FLEXOR DIDGITORUM PROFUNDUS- MEDIAN/ULNAR NERVE
PRONATOR QUADRATUS- MEDIAN NERVE

13. DEEP MUSCLES OF FOREARM

14. POSTERIOR MUSCLES OF FOREARM
Extensors

OPPONENES DIGITI MINIMI
* ALL SUPPLIED BY THE ULNAR NERVE

21. THENAR AND HYPOTHENAR MUSCLES

22. MIDPALMAR MUSCLES A)LUMBRICALS 4 IN NUMBER( NONE TO THUMB) WORM SHAPED
ARISE FROM THE TENDON OF FDP
