palmar ligaments

pal·mar lig·a·ments

[TA]
the fibrocartilaginous plates, one located on the anterior aspect of each metacarpophalangeal and interphalangeal joint of the hand, which are firmly attached to the bases of the phalanges and the heads of the next proximal bones; they are grooved to accommodate the long flexor tendons.
See also: palmar ligaments of interphalangeal joints of hand, palmar ligaments of metacarpophalangeal joints.

Similarly, as the wrist is extended, the palmar ligaments are stretched.
As a result, the palmar ligaments do not span as large an arc over the radiocarpal joint during wrist extension as required of the dorsal ligaments during wrist flexion, allowing more radial deviation before the ligament becomes taut.
