Anatomia do crânio

|Regional anatomy |

|SKULL |

|The skull has 22 bones, excluding the ossicles of the ear. Except for the mandible, which forms the lower jaw, the bones of |
|the skull are attached to each other by sutures, are immobile, and form the cranium. |

|The cranium can be subdivided into: |
|an upper domed part (the calvaria), which covers the cranial cavity containing the brain; |
|a base that consists of the floor of the cranial cavity; and |
|a lower anterior part-the facial skeleton (viscerocranium). |

|The bones forming the calvaria are mainly the paired temporal and parietal bones, and parts of the unpaired frontal, sphenoid,|
|and occipital bones. |

|The bones forming the base of the cranium are mainly parts of the sphenoid, temporal, and occipital bones. |

|The bones forming the facial skeleton are the paired nasal bones, palatine bones, lacrimal bones, zygomatic bones, maxillae, |
|inferior nasal conchae, and the unpaired vomer. |

|The mandible is not part of the cranium nor part of the facial skeleton. |
