CAUTION • The Transplantation and Anatomy Act 1979 (Qld) binds all persons and is, thereby, relevant to all UQ anatomy students. • It is stated under s36 (2) of the Act : “A person who performs an anatomical examination upon a body shall do so in a quiet, orderly and decent manner”. This requirement shall be met for any and all use of donated human tissues at UQ . This includes, but is not limited to: – tissue use by students during attendance at the Gross Anatomy Facility; – hardcopy use of images of donated tissues; – accessing UQ lecture notes or other online UQ anatomy resources containing references to, or images of, donated human tissues; – use of notes inside or outside of class time. • The SBMS Code of Conduct for Use of Donated Human Tissues equally applies. www.legislation.qld.gov.au/Acts_SLs/ Superseded/SUPERS_T/Transpl_Anat A79.htm Do not remove this notice.

The skull is the most complex part of the human skeleton . It is comprised of 22 bones and has 7 other associated elements (including the tiniest bones of the body, namely the auditory ossicles).

Face (14) Maxillary bones (2) Palatine bones (2) Nasal bones (2) Vomer (1) Inferior nasal conchae (2) Zygomatic bones (2) Lacrimal bones (2) Mandible (1) Skull (22) Calvaria (8) Occipital bone (1) Parietal bones (2) Frontal bone (1) Temporal bones (2) Sphenoid (1) Ethmoid (1) Associated bones (7) Auditory ossicles: Malleus (2) Incus (2) Stapes (2) Hyoid bone (1) Maxillary bones (2) Palatine bones (2) Nasal bones (2) Vomer (1) Inferior nasal conchae (2) Zygomatic bones (2) Lacrimal bones (2) Mandible (1)

The morphology of the skull changes throughout the human life cycle. Characteristic is downward forward growth of face to adulthood. (Brain develops most quickly of all tissues and is 90% adult size by age of 5 years.) Tooth loss then has biggest impact on skull morphology as individuals age. (Loss of mechanical force transmission with associated bone resorption.) https://openi.nlm.nih.gov/detailedresult.php?img=PMC3331816_1475-2875-11-64-1&req=4
