Skull Flashcards
External acoustic meatus
Between Ramus of mandible and mastoid process….a hole in the temporal cranial bone allowing the passage of sound to enter the inner ear
Coronal suture
Top of head between frontal and parietal cranial bones.. One of the major joints or sutures between the plates of the frontal and parietal cranial bones
Ethmoid bones
Eye cavity. A cranial bone forming part of the eye cavity
Forehead boss or frontal tuberosity
Forehead. A feature of the frontal bone that forms the “bumps” in the forehead above the eyebrows
Frontal bone
Top of face (forehead) and front top of head. One of the main cranial bones that forms the forehead and front top of head; roughly covers the frontal lobes of the brain
Glabella
Center of forehead. Between the eyebrows
Lacrimal bone
Inner corner of eye socket. A small bone forming a cavity for the tear gland
Lambdoid suture
Back of head. Suture or joint between the occipital and parietal cranial bones
Mandible or jaw bone
Lower part of jaw. The lower jaw bone is the only skull bone that moves, I.e. , during mastication, speech, and expression;carries the lower teeth
Maxilla
Upper part of jaw. The two maxillae form the center of the face with many attaching muscles; carry the upper teeth; form part of the eye orbit; act like keystones into which the other facial bones fit
Mastoid process
Lower part of temporal bone, behind Ramus of jaw.. Built up area of the lower temporal bone where important neck muscles attach
Mental protuberance
Chin boss. A feature of the mandible at the lower front part of the chin which underlies part of the chin boss
Mental tuberosities
Chin boss. A dual bulbous formation of the mandible that underlines part of the chin boss
Nasal bone
Nose. Forms the upper part of the nose and nasal bridge; the lower part of the bridge is formed of cartilage
Nasal concha
Nasal cavity. Formations creating part of the nasal cavity
Nasal spine
Center of nose. Feature of maxilla facial bone at center of nose to which septum is attached
Occipital bone
The lower or rear of the head. A major cranial bone at the lower back of the head; covers occipital lobe of the brain
Parietal bone
Top side of head. A major cranial bone that forms the top back and side of head and roughly covers the parietal lobe of the brain
Ramus of mandible
Back part of mandible. The more vertical part of the mandible
Sphenoid bone
Temple and eye orbit area. A cranial bone that forms part of the eye cavity
Squamosal suture
Side of head between parietal and temporal bones
Supraorbial foramen
Upper orbit of eye
Supra orbital process
Eyebrows. A formation of the frontal bone above the orbit of the eye, under and above the eyebrows that affect the appearance of the eyebrows
Temporal bone
Side of the head, above the ear. A cranial bone in the side of the head that roughly covers the temporal lobe of the brain; it extends down behind the ear toward the jaw
Temporal lines
Front part of temple and lower part of frontal bones. Lines in the frontal bone around the temple
Vomer
Nasal cavity. A facial bone on the centerline of the nose that forms part of the nasal cavity
Zygomatic bone
Cheek. The principle cheek bone; origin of zygomatic and other facial muscles
Zygomatic process
Bones bordering zygomatic bone. The temporal and maxilla bones have areas next to the zygomatic bone
