THE MUSCLES OF THE ARM FLEXORS/EXTENSORS THE MUSCLES OF THE FOREARM FLEXORS/EXTENSORS THE ANTERIOR MUSCLES OF THE FOREARM THE MUSCLES OF THE FOREARM FLEXORS/EXTENSORS CONT’D THE POSTERIOR FOREARM MUSCLES  THE CUBITAL FOSSA INTRODUCTION: V-SHAPED INTERVAL ON ANTERIOR ELBOW BOUNDARIES:  MEDIAL : Pronator teres muscle  LATERAL: Brachioradialis muscle  SUPERIOR/BASE: Imaginary horizonal lines between humeral epicondyles  ROOF: a fascial roof(deep fascia of arm&forearm) strengthened by the bicipital aponeurosis  FLOOR: Brachialis and Supinator muscles  THE CUBITAL FOSSA CONT’D  CONTENT (lateral to medial): Radial nerve, biceps brachii tendon, brachial artery, and median nerve (mnemonic device: Ron Beats Bad Man) DIAGRAM OF CUBITAL FOSSA  APPLIED ANATOMY  Venipuncture in the Cubital Fossa: The fossa is the common site for sampling and transfusion of blood and intravenous injections because of the prominence and accessibility of veins. Usually, the median cubital vein or basilic vein is selected. The cubital veins are also a site for the introduction of cardiac catheters to secure blood samples from the great vessels and chambers of the heart.
