Study Notes
Anatomy of the Skull: Key Points
- The skull is comprised of the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones, each with distinct features and functions.
- The frontal bone includes the glabella, supraorbital margin, and zygomatic process, which articulate with other bones and form the superior side of the orbits.
- The temporal bones resemble a headset and contain various elevations and openings, such as the external acoustic and internal acoustic meatus, mandibular fossa, and mastoid process.
- The occipital bone features the foramen magnum, occipital condyle, hypoglossal canal, and external occipital crest, serving as key structures for brain stem passage and vertebral articulation.
- The sphenoid bone resembles a butterfly and has greater and lesser wings, superior and inferior orbital fissures, optic canal, sella turcica, and various foramina, contributing to the skull's structural integrity.
- The ethmoid bone resembles a flower with wilted leaves and consists of the cribriform plate, crista galli, perpendicular plate, superior and middle nasal conchae, crucial for supporting the nasal cavity and olfactory functions.
- The skull also contains additional openings between bones, such as the foramen lacerum, jugular foramen, and carotid canal, facilitating the passage of nerves and blood vessels.
- A mnemonic image is provided to aid in remembering the openings in the skull, relating them to a cowboy sitting on a saddle and holding reins.
- The cranial nerve exits are associated with specific openings in the skull, such as the olfactory nerve through the cribriform plate and the optic nerve through the optic canal.
- The cranial fossae are regions formed by the floor of the cranial cavity, housing the frontal lobes, temporal lobes, brainstem, and cerebellum.
- The facial bones, including zygomatic bones, lacrimal bone, nasal bones, vomer, inferior nasal conchae, palatine bones, maxilla bones, and mandible, contribute to the structure and support of the face.
- Each facial bone has distinct features, such as the zygomatic bones' temporal, frontal, and maxillary processes, and the vomer's ala and vertical plate, which contribute to the structural integrity of the face and nasal septum.
