El músculo extensor cubital del carpo es un músculo situado en el compartimento superficial de la parte posterior del antebrazo. Su ubicación medial en el antebrazo permite tanto la aducción como la extensión de la muñeca. El tendón del músculo extensor cubital del carpo atraviesa el sexto compartimento extensor de la muñeca. Inserciones: se origina en el epicóndilo lateral del húmero y en el borde posterior del cúbito. Se inserta en la base del quinto metacarpiano. Acciones: extensión y aducción de la muñeca. Inervación: nervio radial (rama profunda). Irrigación sanguínea: arteria cubital. By TeachMeSeries Ltd (2026) Fig. 1: los músculos de la capa superficial de la parte posterior del antebrazo.

Learn More Frequent questions What is the extensor carpi ulnaris muscle? The extensor carpi ulnaris is a muscle located in the superficial compartment of the posterior forearm, responsible for wrist extension and adduction. It plays a key role in movements involving the wrist. Where does the extensor carpi ulnaris muscle originate and insert? This muscle originates from the lateral epicondyle of the humerus and the posterior border of the ulna, inserting at the base of the fifth metacarpal. Its specific attachments facilitate its functional movements. What actions are performed by the extensor carpi ulnaris? The primary actions of the extensor carpi ulnaris include extension and adduction of the wrist. These movements are essential for various hand and wrist functions. Which nerve innervates the extensor carpi ulnaris muscle? The extensor carpi ulnaris is innervated by the deep branch of the radial nerve. This nerve supply is crucial for the muscle's motor function. What is the blood supply to the extensor carpi ulnaris muscle? The blood supply to the extensor carpi ulnaris comes from the ulnar artery. This vascularisation supports the muscle's metabolic needs during activity. Valora este artículo
