Definition of hamulus in US English:



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

    • ‘An enlarged hamulus may articulate with the maxillary process of the zygomatic bone.’
    • ‘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 tensor palatini muscle joins this muscular sling as it sweeps around the hamulus, a bony prominence of the lateral palate.’
    • ‘The maxillary process may articulate with the lacrimal hamulus.’


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