Definition of hamulus in English:



Anatomy Zoology
  • A small hook or hook-like projection, especially one of a number linking the fore- and hindwings of a bee or wasp.

    • ‘It arises from the ulna, on its medial or volar surface, and is inserted onto the pisiform bone, the hamulus, the proximal end of the fifth metacarpal, the capsule of carpal articulations, or abductor digiti quinti.’
    • ‘It curves laterally at its distal end into a hook-like process, the pterygoid hamulus, around which the tendon of the Tensor veli palatini glides.’
    • ‘The maxillary process may articulate with the lacrimal hamulus.’
    • ‘An enlarged hamulus may articulate with the maxillary process of the zygomatic bone.’
    • ‘The tensor palatini muscle joins this muscular sling as it sweeps around the hamulus, a bony prominence of the lateral palate.’


Early 18th century: from Latin, diminutive of hamus hook.
