Hamulus of hamate bone
Encyclopedia
The volar
(pertaining to the palm) surface of the hamate bone
presents, at its lower and ulnar side, a curved, hook-like process, the hamulus, directed forward and lateralward.
This process gives attachment, by its apex, to the transverse carpal ligament and the Flexor carpi ulnaris; by its medial surface to the Flexor digiti minimi brevis
and Opponens digiti minimi; its lateral side is grooved for the passage of the Flexor tendons into the palm of the hand.
It is one of the four eminences on the front of the carpus
to which the transverse carpal ligament of the wrist is attached; the others being the pisiform medially, the oblique ridge of the greater multangular and the tubercle of the scaphoid laterally.

Hamate bone
The hamate bone is a bone in the human hand that may be readily distinguished by its wedge-shaped form, and the hook-like process which projects from its volar surface. It is situated at the medial and lower angle of the carpus, with its base downward, resting on the fourth and fifth metacarpal...

Carpus
In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers , whereas those of the metacarpus do. The corresponding part of the foot is the tarsus...
