Irregular bones serve some various purposes in the body, such as: protection of nervous tissue (such as the [[vertebrae]] protect the [[spinal cord]]), affording multiple anchor points for [[skeletal muscle]] attachment (as with the [[sacrum]]), and maintaining [[pharynx]] and [[Vertebrate trachea|trachea]] support, and [[tongue]] attachment (such as the [[hyoid]] bone). They consist of [[cancellous tissue]] enclosed within a thin layer of [[compact bone]]. The irregular bones are: the [[vertebræ]], [[sacrum]], [[coccyx]], [[temporal bone|temporal]], [[sphenoid]], [[ethmoid]], [[zygomatic bone|zygomatic]], [[maxilla]], [[mandible]], [[palatine bone|palatine]], [[inferior nasal concha]], and [[hyoid]]. ==References== *[http://216.251.232.159/semdweb/internetsomd/ASP/1496564.asp Stedman's Online Medical Dictionary, 27th Edition] {{Gray's}} {{Bone and cartilage}} [[Category:Irregular bones| ]] {{musculoskeletal-stub}} [[pl:Kości różnokształtne]] [[simple:Irregular bone]] [[th:กระดูกรูปร่างไม่แน่นอน]]
