==== Palmar flexion/dorsiflexion ==== During '''palmar flexion''' the proximal carpal bones are displaced towards the ''dorsal'' side and towards the ''palmar'' side during '''dorsiflexion'''. While flexion and extension consist of movements around a pair of transverse axes — passing through the lunate bone for the proximal row and through the capitate bone for the distal row — palmar flexion occurs mainly in the [[radiocarpal joint]] and dorsiflexion in the [[midcarpal joint]]. <ref name="Platzer-134" /> Dorsiflexion is produced by (in order of importance) [[Extensor digitorum muscle|extensor digitorum]], [[Extensor carpi radialis longus muscle|extensor carpi radialis longus]], [[Extensor carpi radialis brevis muscle|extensor carpi radialis brevis]], [[Extensor indicis muscle|extensor indicis]], [[Extensor pollicis longus muscle|extensor pollicis longus]], and [[Extensor digiti minimi muscle|extensor digiti minimi]]. Palmar flexion is produced by (in order of importance) [[Flexor digitorum superficialis muscle|flexor digitorum superficialis]], [[Flexor digitorum profundus muscle|flexor digitorum profundus]], [[Flexor carpi ulnaris muscle|flexor carpi ulnaris]], [[Flexor pollicis longus muscle|flexor pollicis longus]], [[Flexor carpi radialis muscle|flexor carpi radialis]], and [[Abductor pollicis longus muscle|abductor pollicis longus]]. <ref name="Platzer-172" />
