Learn More Trayecto El nervio cutáneo lateral del antebrazo surge como una continuación del nervio musculocutáneo dentro del techo de la fosa cubital. Discurre a lo largo del borde lateral del tendón del bíceps braquial y por debajo de la vena cefálica. Luego se divide en las ramas anterior y posterior: Rama anterior: desciende por la cara anterolateral del antebrazo hasta la muñeca, donde se sitúa anterior a la arteria radial. Inerva la piel de la cara anterolateral del antebrazo. En la base de la eminencia tenar, el nervio termina en varias ramas pequeñas. Rama dorsal: desciende por la cara posterolateral del antebrazo hasta la muñeca. Proporciona inervación cutánea a una pequeña zona de la parte posterolateral del antebrazo.

The cutaneous lateral nerve of the forearm is a sensory nerve that continues from the musculocutaneous nerve. It supplies sensory innervation to the skin on the lateral aspect of the forearm. What is the pathway of the cutaneous lateral nerve of the forearm? The nerve arises as a continuation of the musculocutaneous nerve within the cubital fossa and runs along the lateral edge of the biceps brachii tendon. It then branches into anterior and posterior divisions as it approaches the wrist. What does the anterior branch of the cutaneous lateral nerve innervate? The anterior branch descends along the anterolateral side of the forearm, providing sensory innervation to the skin in this area. It terminates in small branches at the base of the thenar eminence. What area does the dorsal branch of the cutaneous lateral nerve supply? The dorsal branch descends on the posterolateral side of the forearm and supplies sensory innervation to a small region of the skin in that area. This branch is important for sensation in the posterior aspect of the forearm. What is the clinical relevance of the cutaneous lateral nerve of the forearm? Understanding the cutaneous lateral nerve is crucial for diagnosing sensory deficits or injuries in the lateral forearm. Its role in providing sensory innervation makes it significant in assessing nerve damage or conditions affecting sensation in this region. Rate This Article
