What shape is the popliteal fossa, and where is it located?
Diamond between the muscles in the posterior knee.
What are the borders of the popliteal fossa?
Superior - Biceps femoris + semi membranosus + semitendinosus.
Inferior - 2 heads of gastrocnemius
Floor - femur + joint capsule + popliteus
Roof - deep fascia
What are the contents of the popliteal fossa?
Popliteal artery and vein. Common peroneal nerve and tibial nerve. Small group of lymphatics.
What shape is the cubital fossa, and where is it?

Imaginary line between epicondyles of humerus.
What is the lateral border of the cubital fossa?
brachioradialis muscle.
What is the medial border of the cubital fossa?
pronator teres
What is the floor of the cubital fossa?
Brachialis muscle and supinator.
What is the roof of the cubital fossa?
deep fascia and bicipital aponeurosis, with superficial veins
Which nerves travel in the cubital fossa?
Mdian and radial.
Which arteries travel in the cubital fossa?
Brachial artery. Lateral to median nerve. (Note, the ulnar nerve passes posterior to the medial epicondyle so is not in the cubital fossa.)
Which tendon lies in the cubital fossa?
Biceps brachii tendon lateral to brachial artery. attaches to radial tuberosity.
