The pterygoid hamulus is part of the medial pterygoid plate of the sphenoid bone of the skull. Its tip is rounded off. [ 1 ] It has an average length of 7.2 mm, an average depth of 1.4 mm, and an average width of 2.3 mm. [ 1 ] The tendon of tensor veli palatini muscle glides around it.
Soon after, the centers for the postsphenoid part of the body appear, one on either side of the sella turcica, and become blended together about the middle of fetal life. 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 lateral pterygoid plate of the sphenoid (or lateral lamina of pterygoid process) is broad, thin, and everted and forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone, and serves as the origin of the lateral pterygoid muscle, which functions in allowing the mandible to move in a lateral and medial direction, or from side-to-side.
Hamate bone of the left hand. Hamulus shown in red. The hook of hamate (Latin: hamulus) is found at the proximal, ulnar side of the hamate bone. The hook is a curved, hook-like process that projects 1–2 mm distally and radially. [5] The ulnar nerve hooks around the hook of hamate as it crosses towards the medial side of hand.
The pterygomandibular raphe (pterygomandibular fold [1] or pterygomandibular ligament) is a thin [2] tendinous band of buccopharyngeal fascia.It is attached superiorly to the pterygoid hamulus of the medial pterygoid plate, and inferiorly to the posterior end of the mylohyoid line of the mandible.
The pisiform bone is most recognizable as an unassuming palmar projection forming the heel of human hand. [2]The pisiform bone, along with the hamulus of the hamate, defines the medial boundary of the carpal tunnel [2] because the pisiform body acts as one of the four attachments points of the flexor retinaculum.

Haisl also noted that Nová is “under the supervision of top doctors,” and said she would not be competing in the weekend’s World Cup women’s downhill races as previously scheduled.
The lacrimal hamulus is a small, hook-like bony projection of the lacrimal bone. It is a continuation of the posterior lacrimal crest. It articulates with the lacrimal tubercle of the maxilla, and completes the upper orifice of the lacrimal canaliculus. It sometimes exists as a separate piece, and is then called the lesser lacrimal bone.
