The dorsal intercarpal ligament consists of a series of fibrous bands that extend transversely across the dorsal surfaces of the carpal bones, connecting them to each other. v t
The dorsal radiocarpal ligament (posterior ligament) is less thick and strong than its volar counterpart, and has a proximal attachment to the posterior border of the distal radius. Its fibers run medially and inferiorly to form a distal attachment at the dorsal surfaces of the scaphoid (navicular bone of the hand), lunate , and triquetral .
The dorsal intercarpal ligament are two in number and placed transversely behind the bones of the first row; they connect the scaphoid and lunate, and the lunate and triquetrum. The palmar intercarpal ligaments are also two, connect the scaphoid and lunate, and the lunate and triangular; they are less strong than the dorsal, and placed very ...
On the dorsal side of the hand, the palmar carpal ligament corresponds in location and structure to the extensor retinaculum, both being formations of the antebrachial fascia and therefore continuous. Consequently, the flexor retinaculum is commonly referred to as the transverse carpal ligament to avoid confusion. [4]
The scapholunate ligament is an intraarticular ligament binding the scaphoid and lunate bones of the wrist together. It is divided into three areas, dorsal, proximal and palmar, with the dorsal segment being the strongest part. [3] It is the main stabilizer of the scaphoid. In contrast to the scapholunate ligament, the lunotriquetral ligament ...
The dorsal surface is rough for the attachment of ligaments. The volar surface presents, on its medial part, an oval facet, for articulation with the pisiform; its lateral part is rough for ligamentous attachment. The lateral surface, the base of the pyramid, is marked by a flat, quadrilateral facet, for articulation with the lunate.
The dorsal carpometacarpal ligaments, the strongest and most distinct carpometacarpal ligaments, connect the carpal and metacarpal bones on their dorsal surfaces. The second metacarpal bone receives two fasciculi , one from the greater, the other from the lesser multangular .
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
