Upper Limb Flashcards
Surgical Vs Anatomical Neck
Structure running immediately lateral to less tubercle of humerus
Long head of the biceps brachii runs in the intertubercular groove
Inserts on supraglenoid tubercle
Structure connecting underside of clavicle to coracoid process
Trapezoid and conoid components of the coracoclavicular ligament
Distal Humerus anatomy
Extends around radial head to allow rotation
Annular ligament - in which radial head articulates with capitulum
Common flexor origin
Medial humeral epicondyle (tennis elbow site)
Proximal ulnar anatomy
On an axillary view
The lesser tubercle is anterior so same side as a corocoid
C - Spine of scapula
D - Conoid tubercle of clavicle
E - Corocoid process
Conoid tubercle - anatomical variant
3 Muscles attached to corocoid
Pec Minor
Coracobrachialis
Biceps Brachii (short head)
Remember coracoid is anterior (B) so
D - is body
A - is spine
Muscle in the subacromial joint space
Supraspinatous muscle
Ossification of the elbow
CRITOL
Roughly at 1,3,5,7,9,11
Ossification of the hand
Capitate 2-4 m
Hamate 3-6 m
Triquetral 2-3 y
Lunate 4-5 y
Trapezium 6y
Trapezoid 6-7 years
Scaphoid 6-7 years
Pisiform 11-12 years
A - OLECRANON EPIPHYSIS
B - Med. Condyle Apohysis
C - TROCHLEAR EPIPHYSIS
D - Radial epiphysis
E - Capitulum epiphysis
A - Corocoid - so anterior
B - Glenoid of scapular
C - Clavicle
D - Acromion
E - Scapula
Origins and insertion of biceps
Short head: coracoid process of the scapula.
Long head: Supraglenoid tubercle
Insertion: Radial tuberosity and bicipital aponeurosis into deep fascia on medial part of forearm
Labelled swimmers view
Subscapularis attaches to…
Lesser humeral tuberosity
Supraspinatus tendon inserts onto the
Superior facet of the greater tubercle of the humerus
Thumb sesamoid lies in…
Flexor Pollicis Longus
English = Capitulum
LESS TUBEROSITY ON
Os acromiale
Coalition of lunate and triquetral
Spine of scapula is more posterior and continuous with acromion
http://terminologia-anatomica.org/en/Search?query=scapula
Superior edge of scapula NOT scapula blade
Continuous with the glenoid

Radial and ulnar arteries terminate as the…
superficial and deep palmar arches
Just distal to the origin of the ulnar artery, it gives off
The common interosseus artery that then divides into anterior and posterior interosseous arteries
A - Axiliary artery
B - circumflex humeral artery
C - Brachial artery
D - Profunda Brachii
E - Superficial ulnar collateral artery
Axillary artery becomes brachial artery at the…
Lower border of teres major muscle
Final branches of axillary artery
Anterior and posterior circumflex humeral arteries
B is medial - Basilic
A - Cephalic
C - Median Antecubital Vein
E - Trochlear
Axillary vein formed by
Basilic and paired brachial veins
Cephalic then joins this
E - corocoid so anterior
D - just below clavicle so SUPRAspinatus
B - more posteromedial to supraspinatus = infraspinatus
A - Teres minor
