The recurrent branch of median nerve (thenar muscular branch) is small motor branch of the median nerve in the hand. It supplies the thenar muscles of the hand, which are associated with fine movements of the thumb.

Learn More Course The recurrent branch of median nerve is a branch of the median nerve in the hand. It typically arises distal to the flexor retinaculum, after which it curls proximally and laterally around the distal border of the ligament to supply the thenar muscles. The origin of the recurrent branch is variable within the population, with two recognised aberrations: Sub-ligamentous – arises within the carpal tunnel and courses underneath the flexor retinaculum before reaching the thenar muscles. Trans-ligamentous – arises within the carpal tunnel and pieces the flexor retinaculum to reach the thenar muscles.

Learn More Supply The recurrent branch of median nerve supplies muscles in the thenar eminence (mainly T1 but with some contribution from C8): Flexor pollicis brevis – flexes the thumb. Abductor pollicis brevis – abducts the thumb. Opponens pollicis – opposes the thumb. By TeachMeSeries Ltd (2025) Fig 2Palmar view of the thenar muscles. Print Article Rate This Article
