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 pterygoid hamulus is a hook-like process at the lower extremity of the medial pterygoid plate of the sphenoid bone of the skull. It is the superior origin of the pterygomandibular raphe , and the levator veli palatini muscle .
The soleal line, also known as the popliteal line (in older texts), is a prominent ridge on the posterior surface of the tibia.It is the site of many muscle origins and insertions, such as those of popliteus muscle, soleus muscle, flexor digitorum longus muscle, and tibialis posterior muscle.
Hamulus is the diminutive – hooklet or little hook. The plural is hamuli. Adjectives are hamate and hamulate, as in "a hamulate wing-coupling", in which the wings of certain insects in flight are joined by hooking hamuli on one wing into folds on a matching wing. Hamulate can also mean "having hamuli".
The center of the body is defined as the midsagittal or longitudinal plane. [3] These terms come from Latin words with similar meanings, ab-being the Latin prefix indicating ' away ', ad-indicating ' toward ', and ducere meaning ' to draw or pull '. [b] Abduction is a motion that pulls a structure or part away from the midline of the body ...
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). The medial joins the lateral pterygoid plate about the sixth month.
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.

Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
