- n. Pl. hamuli (-lī). A little hook or hooklet. Specifically— In anatomy, a hook-like process of a bone. The hamulus lacrymalis is the hook-like process at the lower end of the vertical ridge of the lacrymal bone, which helps to bound the upper orifice of the lacrymal canal. The hamulus pterygoideus is the hook-like process of the pterygoid portion of the sphenoid bone, over which runs the tendon of the tensor palati muscle. (See cut under
craniofacial.) The hamulus laminæ spiralis is the hook-like process in which the osseous spiral lamina ends at the apex of the cochlea.
- n. [capitalized] In zoology, a genus of mollusks.

“Between the tendon and the hamulus is a small bursa.”
“The volar surface presents, at its lower and ulnar side, a curved, hook-like process, the hamulus, directed forward and lateralward.”
“The rest of the volar surface of the bony carpus is covered by tendons and the transverse carpal ligament, and is entirely concealed, with the exception of the hamulus of the hamate bone, which, however, is difficult to define.”
“It arises from the convex surface of the hamulus of the hamate bone, and the volar surface of the transverse carpal ligament, and is inserted into the ulnar side of the base of the first phalanx of the little finger.”
“It arises from the convexity of the hamulus of the hamate bone, and contiguous portion of the transverse carpal ligament; it is inserted into the whole length of the metacarpal bone of the little finger, along its ulnar margin.”
“It is attached, medially, to the pisiform and the hamulus of the hamate bone; laterally, to the tuberosity of the navicular, and to the medial part of the volar surface and the ridge of the greater multangular.”
“The pterygomandibular raphé (pterygomandibular ligament) is a tendinous band of the buccopharyngeal fascia, attached by one extremity to the hamulus of the medial pterygoid plate, and by the other to the posterior end of the mylohyoid line of the mandible.”
“Descending vertically between the medial pterygoid plate and the Pterygoideus internus it ends in a tendon which winds around the pterygoid hamulus, being retained in this situation by some of the fibers of origin of the Pterygoideus internus.”
“The crest, with a part of the orbital surface immediately behind it, gives origin to the lacrimal part of the Orbicularis oculi and ends below in a small, hook-like projection, the lacrimal hamulus, which articulates with the lacrimal tubercle of the maxilla, and completes the upper orifice of the lacrimal canal; it sometimes exists as a separate piece, and is then called the lesser lacrimal bone.”
“The medial pterygoid plate is long and narrow; on the lateral side of its base is the scaphoid fossa, for the origin of the Tensor veli palatini, and at its lower extremity the hamulus, around which the tendon of this muscle turns.”
