Upper Limb Flashcards
Carrying angle
Angle between the short lateral part and longer medial part of trochlea
Over head abduction (above 90)
Serrated anterior and trapezius
15 degrees abduction
Supraspinatus
90 degrees abduction
Deltoid
Incision of axilla
On the floor more medially to avoid vessels on the lateral wall
Pushing and punching muscles
Serratus anterior and p. Minor
Scaphoid scapular
Concavity of medial border of scapular
Relations of artery and nerve at suprascapular foramen
Nerve below (within the foramen) Artery above
Long head of biceps brachi is intracapsular
Because capsule of shoulder joint covers the supraglenoid tubercle
Long head of triceps brachi is extracapsular
Because the capsule of shoulder joint does not cover the infraglenoid tubercle
Upper lateral cutaneous nerve of arm
From posterior division of ancillary nerve
Which also gives pseudo ganglion to Teres minor
Lateral cutaneous nerve of forearm
From musculocutaneous
Course of median nerve in forearm
Between two heads of pronator teres
Course of ulna nerve at elbow
Behind medial epicondyle and between two heads of flexor carpi ulnaris
Tendon of flexor carpi ulnaris inserts into
Pisiform
Tendon of flexor carpi radialis inserts into
Base of second metacarpal
Axillary nerve supplies
Anterior division: deltoid
Posterior division: deltoid and teres minor
Musculocutaneous nerve supplies
Coracobrachialis
Brachialis
Biceps brachii
Median nerve supplies
Pronator teres
Pronator quadratus
Flexor carpi radialis
Palmaris longus
Ulna nerve supplies
Flexor carpi ulnaris
Radial nerve supplies
Triceps brachii Anconeous Brachioradialis Supinator 3 wrist extensors
Pre axial vein is called
Cephalic vein
Post axial vein is called
Basilic vein
Branches from radial nerve @ radial groove
Lower lateral cutaneous nerve of arm
Posterior cutaneous nerve of forearm
Lymphangitis, lymphadenitis and lymphoedema
Inflammation of lymph vessels
Inflammation of lymph nodes
Accumulation of fluid in lymph vessel due to an obstruction
Bicupital aponeurosis
Flat tendon of biceps brachii that enters into the deep fascia
Cubital tunnel
Between two heads of flexor carpi ulnaris
Median artery
Branch of anterior interosseous artery from ulna artery.
Accompanies median nerve
Radial and ulna arteries lies above or below flexor retinaculum?
Above
Median, ulnar and radial nerves passes between which muscles respectively in the forearm?
Two heads of pronator teres
Two heads of flex carp ulnaris (carpal tunnel)
Supinator muscle
Long flexors of hand
Flexor digitorum superficialis and profundus
What keeps the long flexors of the hand in place during flexion
Flexor sheath
How does flexor sheath permit flexion?
By being thick opposite the phalanges and thin opposite the joints
Opposition is a mixture of what movements?
Flexion and medial rotation
Why is adduction and abduction of thumb at 90 degrees to other fingers?
Because the fifth metacarpal is rotated medially at 90 degrees
Action of paradox?
Marked flexion of the distal phalanx due to sparing of flexor digitorum profundus at wrist lesion
Muscular supply of median nerve in hand
Abductor pollices brevis
Flexor pollices brevis
Opponens pollices
2 lateral lumbricals
Muscular supply of ulnar in the hand
Palmaris brevis
AFO of hypothenar eminence
2 medial lumbricals
8 interrosei
Tennis elbow
Lateral epicondylitis
Due to micro trauma to the area
How many degrees is the carrying angle
13 degrees
Increase in carrying angle
Cubitus valgus
Decrease in carrying angle
Cubitus varum
Synostisis
Fusion of bones e.g upper parts of radius and ulna
Chief pronator
Pronator quadratus
supinators
Biceps brachii ( in semi flexed) Supinator (in extended arm)
Syndactylyl
Abnormal fusion of bones of fingers or toes
Polydactyl
Extra fingers or toes
Ectrodactylyl
Absence of fingers or toes
