L'ostéologie désigne la science qui étudie la structure des os et plus généralement du squelette, humain ou animal. Il s'agit d'une sous-discipline de l'anatomie, de l'archéologie et de l'anthropologie lorsqu'elle traite du biologique chez l'humain.
Over 20 accessory ossicles have been described. These usually occur because of failure of fusion of ossification centers. Such is the case of the os centrale, an additional bone located on the dorsal aspect between the scaphoid, capitate, and trapezoid, or between the lunate, triquetrum, and hamate.
The auditory ossicles are the three smallest bones in the human body, the malleus, the incus and the stapes. The first is attached to the tympanic membrane, the last to the circumference of the fenestra vestibuli, the incus being placed between and connected to both by delicate articulations.
24 gru 2001 · Ossicles of Holothuria (Metriatyla) scabra Jaeger 1833 vary mainly in early juveniles between 0.9 and 15mm long. While ossicles were not observed in auricularia and doliolaria larvae, which instead possessed elastic balls, ossicles were present in late pentactulae.
28 cze 2011 · The clivus (Blumenbachii) forms the central part of the base of the skull and is therefore an important structure. This osseous region is of great clinical importance because typical pathology, such as chordomas, metastatic tumors, inflammation and fibrous dysplasia, can occur there.
Numerical increment arises from additional or from split bones. Over twenty accessory carpal bones have been described but the commonest are the os centrale carpi, the os radiale externum, the triangular bone and the styloideum bone.
14 cze 2013 · Ossicles of the body wall are predominantly microscopic granules in the adoral half underlain by small plate-like elements . In the lower half of the body, granules become fewer and are joined short tack-like elements (tables), which become particularly abundant in the basal part.
