Boundaries and component of upper arm
Superior/inferior/ posterior/ lateral and medial walls
Medial wall of serratus anterior
Ribs 1-4, humerus, coracobrachialis, short head of biceps
From which nerve plexus innervates the upper limb?
Brachial plexus: musculocutaneous, axillary, brachial, radial and ulnar nerve
Location and tissues served by axillary
Medial side of the axillary artery
- arm, axillia and superolateral chest wall
Location and tissues served by cephalic
Anterior antebrachium
- superficial - runs up the shoulder
Location and tissues served by basilic
Medial aspect of forearm at wrist and runs superficially in forearm via the cubital vein
- dorsal venous network of the hand
Location and tissues served by median cubital
Cubital fossa an anterior /flexor aspect of the elbow joint - crease middle of arm and slightly up and down
Location and tissues served by median antebrachial cutaneous
Superficial forearm vein
- drains superficial structures of the forearm and wrist between basilic and cephalic vein
Location and tissues served by dorsal venous network
Within superficial fascia on the back of the hand
- laterally into cephalic vein and medially into basilic vein
What bones are in the elbow joint?

Name the two major compartments of the upper limb and define their boundary
Lateral and medial septum is the boundary
The two compartments are anterior and posterior
Anatomical boundaries of the 5 compartments of the hand
Thenar - outer thumb
Hypothenar - metacarpal outer portion of 5th phalanx
Adductor - metacarpal thumb + 3rd fingers
Central - between metacarpals attaches to the tendon
Interosseous between metacarpals
What is aponeurosis?
A thin sheath of connective tissue that helps to connect the muscles to your bones
Name the 4 anterior axio appendicular muscles that move the pectoral girdle and their movement and attachment
Pec minor: 3rd 5th lig to costochondral - depression, abduction, internal rotation, protraction
Pec major: adduction - greater tubercle
Subclavius: stabilization of the sternoclavicular joint - inserts into surface of middle of the grove of the clavicle
Serratus Anterior: 1st - 8/9th rib and medial border of scapula - movement is pulling forward towards thorax
