what bones make up the arm?
- clavicle
- scapula
- humerus
what bones make up the forearm?
- radius
- ulna
what is the depression on anterior aspect of elbow?
cubital fossa
where is the cubital fossa located?
anterior to distal humerus and elbow joint
what is the superior boundary of the cubital fossa?
imaginary line connecting medial and lateral epicondyles
what is the medial border of the cubital fossa?
Flexor muscles arising from medial epicondyle
what is the lateral boundary of the cubital fossa?
Extensor muscles from lateral epicondyle
what is the floor of the cubital fossa?
Brachialis and supinator muscles of arm and forearm
what is the roof of the cubital fossa?
- Deep fascia
- bicipital aponeurosis,
- superficial facia
- skin
what is the Bicipital aponeurosis?
connective tissue membrane that extends from the muscle tendon of the biceps
what is contained in the cubital fossa?
- Terminal brachial artery and commencement of radial and ulnar arteries
- Biceps brachii tendon
- median nerve
- radial nerve
what is contained in the superficial fascia covering the fossa?
- medial cubital vein
- Basilic and cephalic veins
- Medial and lateral cutaneous nerves of forearm
what vein is found on the lateral aspect?
cephalic vein
what vein is found on the medial aspect of the arm?
basilic
what is the connection between the cephalic and the basilic vein?
median cubital vein
what vein is commonly used for injections?
median cubital vein
what is the collection of veins located on the dorsum of the hand?
dorsal venous network
describe the name changes and pathway of the basilic vein to the heart
basilic vein > brachial vein > axillary vein > subclavian vein + internal jugular > brachiocephalic vein > SVC > right atrium
when does the basilic vein become the brachial vein?
when it dives deep
when does the brachial vein become the axillary vein?
upon entering the axilla
when does the axillary vein become the subclavian vein?
at the lateral border of the first rib
where does the cephalic vein drain?
into axillary vein after running through the delto-pectoral groove
what lies deep to the cubital fossa?
- Biceps brachii tendon/aponeurosis
- brachial artery
- medial nerve
- pronator teres
- brachioradialis
what is the arterial supple to the arm and forearm?
arch of aorta > brachiocephalic trunk > subclavian artery > axillary artery > brachial artery > radial artery or ulnar artery
what artery is used to take the peripheral pulse?
radial artery
what spinal nerves make up the brachial plexus ?
C5- T1
where does the medial nerve arise?
brachial plexus
what modalities does the median nerve carry and where does it supple?
- sensory,
- motor
- sympathetic
nerve fibres
that supply structures in the distal upper limb
