Boundaries in anatomy!
Shoulder Region
Space Boundaries Important structure
Triangular space
Superior = teres minor
Inferior = teres major
Lateral = long head of triceps brachii
Circumflex scapular artery
Quadrangular space
Superior = teres minor
Inferior = teres major
Medial = long head of triceps brachii
Lateral = lateral head of triceps brachii/humerus
Axillary nerve
Posterior circumflex humeral artery
Triangular interval
Superior = teres minor
Medial = long head of triceps brachii
Lateral = lateral head of triceps brachii/humerus
Radial nerve
Profunda brachii artery
Deltopectoral Triangle (not tt impt)
Contents- Cephalic vein- Lymph nodes
ARMAxilla
BoundariesApex
- Cervicoaxilllary canal (passageway btwn neck and axilla, bounded by 1st rib, clavicle and superior edge of scapular)
Base- Axillary fossa (armpit, concaved skin)
Anterior wall- Pec major and pec minor (2 layers)- Axillary fold (innermost part of anterior wall formed by pec maj, can be felt w fingers)
Posterior Axillary Wall- Mainly scapular and subscapularis- Inferiorly teres major and latissimus dorsi- Posterior axillary wall (
Lateral Wall- Intertubecular groove of humerus
Medial Wall- Thoracic wall- Serratus anterior
Contents“AXILLA”
AX-axillary artery and vein
I- infraclavicular part of brachial plexus
L- Lymph nodes
L-Long thoracic Nerve and intercostalbrachial nerve
A- Axillary fat and areolar tissue
ForearmCubital Fossa
BoundariesRoof
- continuity of brachial and antebrachial fascia reinforced by bicipital aponeurosis and skin
Floor- Brachialis- Supinator
Medial Boarder- Lateral boarder of pronator teres and flexors of forearm
Lateral Boarder- Medial boarder of brachioradialis and extensors of forearm
Superior Boarder- Imaginary line btwn medial and lateral epicondyles of humerus
Contents“Really need Beer to Be at My Nicest” (lateral to medial) – TAN (tendon, artery, nerve)
Really need–Radial Nerve
Beer to- Brachial tendon
Be at- Brachial artery (location where brachial artery branches into radial and ulnar artery)
My nicest- Median Nerve (median nerve most median)
Wrist (better rmb because we are wristers :P)
Carpal Tunnel
BoundariesFloor
- 8 carpal bones
Base (X connected to FR)
- Capitate- Lunate
Lateral- Scaphoid- Trapezoid
Medial- Pissiform- Hook of hamate
Roof- Flexor retinaculum (FR)/ transverse carpal ligament
Contents (9)- Median nerve (1)- Tendons of FDS (4)- Tendons of FDP (4)- Tendon of FPL (1)
Anatomical Snuff Box
Boundaries – pg 757 of MooresFloor
- Scaphoid- Trapezium
Anterior Boundary- Tendons of APL and EPB
Posterior Boundary- Tendon of EPL
Contents- Radial artery- Superficial branch of radial Nerve (where radial nerve branches into superficial and deep,
where radial nerve leaves forearm)
Guyon’s (ulnar) CanalBoundaries
- Pisiform- Hook of hamate
Contents- Ulnar artery (lateral)- Ulnar nerve (medial)
