Hamate bone
Hamate Bone
The Hamate bone (pronounced: /ˈhæmeɪt/), also known as the unciform bone, is one of the eight small carpal bones that form the wrist, or the carpus. It is located on the ulnar side of the carpus and distinguished by its unique 'hook' feature.
Etymology
The term 'Hamate' is derived from the Latin word 'hamatus', meaning 'hooked', which refers to the hook-like process on the palmar side of the bone.
Structure
The Hamate bone is wedge-shaped, with a narrow end pointing towards the palm. It has a prominent hook-like process, known as the hamulus, which projects from its palmar surface. This hook is a distinguishing feature of the Hamate bone and serves as an attachment point for various ligaments and tendons.
Function
The Hamate bone, along with the other carpal bones, contributes to the flexibility and movement of the wrist. It also provides a surface for the attachment of several muscles, including the Flexor carpi ulnaris and Opponens digiti minimi.
