Between the tendon and the hamulus is a small bursa.

Hamulus is the diminutive - hooklet or little hook.

Hamus, Hamulus and words derived from them, are morphological or anatomical terms in various branches of biology.

In vertebrate anatomy, a hamulus is a small, hook-shaped portion of a bone, or possibly of other hard tissue.

The specific name is a crasis compound word, taken from Latin, of hamulus (small hook), and the feminine form of feros, "to bear."

The palmar presents, at its lower and ulnar side, a curved, hook-like process, the hamulus, directed forward and lateralward.

The species name is derived from Latin hamulus, a diminutive form of hamus and refers to the hook at the apex of the aedeagus.

The medial pterygoid plate of the sphenoid curves laterally at its lower extremity into a hook-like process, the pterygoid hamulus, around which the tendon of the Tensor veli palatini glides.

Cephalotes hamulus is a species of arboreal ant of the genus Cephalotes, characterized by an odd shaped head and the ability to "parachute" by steering their fall if they drop off of the tree they're on.

Near the summit of the cochlea the lamina ends in a hook-shaped process, the hamulus laminae spiralis; this assists in forming the boundary of a small opening, the helicotrema, through which the two scalae communicate with each other.

It is attached, medially, to the pisiform and the hamulus of the hamate bone; laterally, to the tubercle of the scaphoid, and to the medial part of the volar surface and the ridge of the trapezium.

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.

The pterygomandibular raphe (pterygomandibular ligament) is a ligamentous band of the buccopharyngeal fascia, attached superiorly to the hamulus of the medial pterygoid plate, and inferiorly to the posterior end of the mylohyoid line of the mandible.

It arises from the convex surface of the hamulus of the hamate bone, and the palmar surface of the flexor retinaculum of the hand, and is inserted into the ulnar side of the base of the first phalanx of the little finger.

Each medial pterygoid plate (except its hamulus) is ossified in membrane, and its center probably appears about the ninth or tenth week; the hamulus becomes chondrified during the third month, and almost at once ossifies (Fawcett).

Descending vertically between the medial pterygoid plate and the medial pterygoid muscle, 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 medial pterygoid muscle.
