Muscles Of The ARM Flashcards
The anterior and posterior arm are separated by the:
The bicipital aponeurosis ?
What are the 2 divisions of the arm?
Anterior
Posterior
What innervates/ nerve suplythe ANTERIOR ARM?
MUSCULOCUTANEOUS NERVE
What innervates/ nerve suplythe POSTERIOR ARM?
Radial nerve
What are the muscles of the anterior arm?
CORACOBRACHIALIS
BRACHIALIS
BICEPS BRACHII
What are the muscles of the posterior arm?
Triceps brachii
What adducts/ flexes the arm?
What division?
Coracobrachialis
Anterior
Main flexor of the arm?
What division?
BRACHIALIS
Main supinator of the forearm? (And flexes the arm)
What division?
BICEPS BRACHII
Anterior
MainEXTENSOR OF THE ARM?
What division?
Triceps brachii
Posterior
Flexes the arm only. Not the forearm.
What division?
Coracobrachialis
Anterior
Flexes the forearm and not the ARM?
What division?
Brachialis
Biceps brachii
Anterior
Action of the anterior division of the Arm?
FLEXOR
Action of the posterior division of the Arm?
EXTENSOR
What is the other muscle that can SUPINATE?
Supinator
Inability to SUPINATE the FOREARM means injury to the ff muscle:
?SUPINATOR
The flexor muscles of the forearm/ anterior division is innervated by:
MEDIAN NERVE
The extensor muscles of the forearm/ posterior division is innervated by:
RADIAL NERVE
All muscles belonging to the ANTERIOR group of the forearm will be supplied by the: ______ except, ________. & the median half of ________
Supplied by the________
Median nerve
- FCU
- FDP
ULNAR NERVE
The flexor/ anterior group of the forearm is supplied by the median nerve are the ff:
Superficial Pronator teres FCR palmaris longus INTERMEDIATE FDS DEEP GROUP FPL Pronator Quadratus
The flexor/Anterior division of the FOREARM are supplied by the median nerve except:
FCU
and the MEDIAN HALF of the FDP.
PBQ:The common flexor tendon of the anterior division of the forearm is the:
MEDIAL EPICONDYLE OF THE HUMERUS
the MEDIAL EPICONDYLE OF THE HUMERUS
Is the common origin of the ff muscles: (5)
Pronator teres (humeral head) FCR Palmaris Longus FCU ( humeral head) FDS ( humeroilnar head)
The extensor/ posterior division of the forearm are supplied by:
RADIAL NERVE
( no problem with innervation coz all muscles of both ARM & FOREARM are supplied by this nerve.
The muscles of the extensor/ posterior division of the FOREARM are all EXTENSOR except the _____ which is a FLEXOR.
BRACHIORADIALIS
The common EXTENSOR tendon of the forearm is the:
LATERAL EPICONDYLE OF THE HUMERUS
the LATERAL EPICONDYLE OF THE HUMERUS
Is the common origin of the ff muscles: (6)
ECRB ED EDM ECU ANCONEUS SIPINATOR
Pbq: Inflammation of the Common FLEXOR TENDON
Medial epicondylitis or GOLFER’S ELBOW
PBQ:Repetitive FLEXION & PRONATION of the forearm at the elbow
GOLFER’S ELBOW or medial epicondylitis
PBQ: Inflammation of the Common EXTENSOR TENDON
Tennis elbow or LATERAL epicondylitis
PBQ: Results from Repetitive FLEXION & EXTENSION of the forearm at the elbow
Tennis elbow or LATERAL epicondylitis
