Answer 2

Triangular shape, three borders a roof and floor

Question 3

Answer 3

Medial border of brachioradialis muscle

Question 4

Question 5

Answer 5

Horizontal line drawn between epicondyles of humerus

Question 6

Roof

Answer 6

Bicipital aponeurosis, fasica, subcutaneous fat and skin

Question 7

Floor

Answer 7

Brachialis (proximally) and supinator (distally)

Question 8

What is the cubital fossa?

Answer 8

Passageway for structures to pass between upper arm and forearm

Question 9

Radial nerve

Answer 9

Travels along border of cubital fossa, divides into superficial and deep branches
Motor and sensory function in posterior forearm and hand

Question 10

Biceps tendon

Answer 10

Passes centrally though cubital fossa and attaches radial tuberosity (immediately distal to radial neck)
Gives rise to bicipital aponeurosis which contributes to roof of cubital fossa

Question 11

Brachial artery

Answer 11

Bifurcates into radial and ulnar arteries at apex of cubital fossa
Brachial pulse can be felt in cubital fossa by palpating medial to biceps tendon

Question 12

Median nerve

Answer 12

Travels medially through cubital fossae, exiting by passing between two heads of pronator teres
Motor and sensory function in anterior forearm and hand

Question 13

Superficial veins in cubital fossa

Answer 13

Median cubital vein connecting basilic and Cephalic veins
Can be accessed easily (a common site for venepuncture)
