The lunate bone is a carpal located in the hand.
The lunate bone is classified as a carpal bone in the wrist. It is one of the eight small bones that make up the carpal bones in the human hand.
The term for a large rounded articulating knob is "lunate."
The carpus, also known as the wrist bones, consists of eight bones, including the scaphoid, lunate, and triquetrum.
Proximal row (lateral to medial): scaphoid, lunate, triquetral, pisiform bones.
An antisigma is a reversed lunate sigma, the symbol Ↄ.

Ulna
Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, and Hamate.
The ulna does not directly articulate with any carpal bones. Instead, it forms a joint with the triangular fibrocartilage complex (TFCC) located at the wrist, which interfaces with the carpal bones, particularly the lunate and the triquetrum. The radius, however, articulates with the scaphoid and lunate carpal bones.
The joint between radius and scaphoid + lunate should fall into the category of an ellipsoid joint.
