🗑
|
||||
| coronoid process | show 🗑
|
||||
| show | Fibers of the olfactory nerve (I) pass into the nasal cavities on either side. Instead of there being one foramen on each side, there are many foramina. It is found on either side of the crista galli, forming part of the anterior fossa of the cranium.
🗑
|
||||
| crista galli | show 🗑
|
||||
| show | a single bone of the cranium. It is anterior to the sphenoid and posterior to the nasal bones. It forms most of the area between the nasal cavity and the orbit of the eye.

|
||||
| foramen ovale | show 🗑
|
||||
| foramen rotundum | show 🗑
|
||||
| show | This bone is a single bone of the cranium and the face, forming the forehead. It forms the roof for each of the orbits and the majority of the anterior cranial fossa. Superiorly it forms the coronal suture with the parietal bones.
🗑
|
||||
| frontal sinuses | show 🗑
|
||||
| show | This landmark of the sphenoid bone can be seen both on the outer surface of the skull as well as in the middle fossa of the cranium. It also makes up a large portion of the medial wall of the orbit.
🗑
|
||||
| show | Anteriorly the maxillary bone and posteriorly the palatine bone form this structure.
🗑
|
||||
| hyoid bone | show 🗑
|
||||
| show | The hypoglossal nerve XII exits the skull through this structure.
🗑
|
||||
| show | this is cranial nerve XII. It is a motor nerve serving the muscles of tongue. It exits the skull via the hypoglossal canal. It runs with the lingual (sublingual) artery medial to the digastric muscle.
🗑
|
||||
| incus | show 🗑
|
||||
| show | There are two of these structures, one on the lateral wall of each nasal cavity. Their curved surface causes turbulence as air moves into the nasal cavity.
🗑
|
||||
| show | Formed by the maxilla, the greater wing of the sphenoid, the palatine, and the zygomatic bones. The maxillary nerve (V2) passes through this fissure having come from the foramen rotundum and on its way to the infraorbital foramen.
🗑
|
||||
| infraorbital foramen | show 🗑
|
||||
| show | Found on the vertical portion of the petrous ridge of the temporal bone. The facial nerve (VII) and vestibulocochlear (VIII) nerves pass into this canal. They separate once inside the temporal bone.
🗑
|
||||
| jugular foramen | show 🗑
|
||||
| show | These two bones are of the face. They each contain the lacrimal canal which is functionally important as this is the passage for the tear duct. The canal terminates in the nasal cavity.
🗑
|
||||
| show | Found between the occipital bone and the two parietal bones. It is an example of a synostosis
🗑
|
||||
| lesser wing | show 🗑
|
||||
| malleus | show 🗑
|
||||
| show | A single bone of the face. It articulates with the mandibular fossa of the temporal bone and irritation of this joint leads to the condition known as TMJ syndrome. It also houses the mandibular and mental foramina.
🗑
|
||||
| mandibular (sigmoid) notch | show 🗑
|
||||
| show | This is the second foramen that the mandibular nerve (V3) passes through as it moves toward the mental foramen. Dentists usually try to anesthetize this nerve near this foramen when working on teeth in the mandible.
🗑
|
||||
| mandibular fossa | show 🗑
|
||||
| show | This process is part of the temporal bone. It is the insertion for the sternocleidomastoid muscle. In fact it is this muscle that causes this landmark to develop.
🗑
|
||||
| maxillae (maxillary bones) | show 🗑
|
||||
| maxillary nerve (V2) | show 🗑
|
||||
| mental foramen | show 🗑
|
||||
| middle conchae | show 🗑
|
||||
| show | Contains the temporal lobe of the brain and the sphenoid (greater wings) and temporal bones.
🗑
|
||||
| show | These two small bones are considered facial bones. They form the bridge of the nose. They articulate with the maxillary bones laterally, the perpendicular plate of the ethmoid bone posteriorly, and the frontal bone superiorly.
🗑
|
||||
| show | Primarily made up of two bones and a septal cartilage. The superior bone is the perpendicular plate of the ethmoid. The inferior bone is the vomer. The septal cartilage is hyaline cartilage and it projects anteriorly.
🗑
|
||||
| nuchal lines | show 🗑
|
||||
| occipital bone | show 🗑
|
||||
| show | These articulate with the superior articular facets of the atlas (C1). It functions as a hinge joint allowing flexion and extension of the head. This foramen is important as it transmits the hypoglossal nerve (XII).
🗑
|
||||
| show | Found in the cribriform plate of the ethmoid bone and is a sensory nerve for smell.
🗑
|
||||
| optic canal | show 🗑
|
||||
| optic nerve (II) | show 🗑
|
||||
| show | These bones are L-shaped facial bones that form the posterior floor of the nasal cavity and posterior portion of the hard palate.
🗑
|
||||
| show | The portion of the maxillary bone that forms part of the hard palate.
🗑
|
||||
| parietal bone(s) | show 🗑
|
||||
| show | The superior portion of the bony nasal septum, which separates the left and right nasal cavities. It extends inferiorly in the median sagittal plane from the rest of the ethmoid bone.
🗑
|
||||
| petrous ridge | show 🗑
|
||||
| posterior fossa | show 🗑
|
||||
| show | There is a medial and lateral plate for this process. They project inferiorly from the greater wing. The medial process of the sphenoid bone articulate with the perpendicular plates of the palatine bones anteriorly.
🗑
|
||||
| show | This landmark of the mandible is a posterior processes that meets the body at the mandibular angle. The coronoid and condyloid processes project superiorly from the superior edge of this, with the mandibular (sigmoid) notch between them.
🗑
|
||||
| show | This suture is found between the two parietal bones. It is an example of a synostosis.
🗑
|
||||
| sella turcica | show 🗑
|
||||
| show | This single bone is considered a cranial bone. It articulates with every other cranial bone. It also articulates with the zygomatic, vomer, maxillary, and palatine bones. The greater wing and lesser wing are landmarks of this bone.
🗑
|
||||
| show | Most of this suture is found between the temporal bone and the parietal bone on each side of the skull. It is an example of a synostosis. This structure starts as a fontanel in the fetus. Technically these are fibrous joints or ligamentous unions.
🗑
|
||||
| Stapes | show 🗑
|
||||
| show | Part of the temporal bone and is anteromedial to the mastoid process. As is the case with many processes, it forms where muscles attach to the bone.
🗑
|
||||
| show | Surrounds the facial nerve (VII) as it passes away from the cranium toward the face. This is the second of the two foramina it passes through. The order of foramina that it passes through is internal auditory meatus and stylomastoid foramen.
🗑
|
||||
| superior conchae | show 🗑
|
||||
| superior orbital fissure | show 🗑
|
||||
| show | Passageway for the ophthalmic nerve (V1) as it moves onto the face. This is the second of the two foramina it passes through. The order of foramina that it passes through is superior orbital fissure and supraorbital foramen.
🗑
|
||||
| show | Start as fontanels in the fetus & are technically fibrous joints or ligamentous unions. Their flexibility is important during birth for easier passage through the birth canal and growth after the delivery. The fontanels are mostly closed by age 1.
🗑
|
||||
| temporal bone(s) | show 🗑
|
||||
| temporal process | show 🗑
|
||||
| Vomer | show 🗑
|
||||
| zygomatic arch | show 🗑
|
||||
| zygomatic bone | show 🗑
|
||||
| zygomatic process | show 🗑
