Frontal Bone bone that forms the forehead Parietal Bone either of two skull bones between the frontal and occipital bones and forming the top and sides of the cranium occipital bones of the skull back of head Forms posterior and inferior surfaces of the cranium, articulates w the parietal, temporal, and sphenoid bones. Occipital Bone: Foramen Magnum large opening where spinal cord and brain connect Occipital Bone: occipital condyles site of articulation between skull and first vertebra of the neck Occipital Bone: External occipital protuberance the inferior and superior nuchal lines are ridges that intersect the occipital crest. makes the attachment cite of muscles. Temporal Bone bone that forms parts of the side of the skull and floor of the cranial activity. There is a right and left temporal bone. Temporal Bone: External Acoustic Meatus canal leading to the middle ear and eardrum Temporal Bone: Mandibular Fossa the depression in the temporal bone that articulates with the mandible temporal bone: styloid process attachment for muscles of the tongue, throat, and hyoid bone Temporal bone: mastoid process Attachment point for muscles moving head Temporal bone (zygomatic process) articulates with the temporal process of zygomatic bone to form zygomatic arch Maxilla Protects the upper teeth, orbital rim, protects the eye and other structures in the orbit. inferior nasal conchae The lowermost scroll-shaped bones on the sidewalls of the nasal cavity. palatine bone either of two irregularly shaped bones that form the back of the hard palate and helps to form the nasal cavity and the floor of the orbits coronal suture the suture between the parietal and frontal bones of the skull sagittal suture between parietal bones lambdoid suture between parietal bones and occipital bone squamous suture Between parietal and temporal bones crista galli Bony landmark or ridge that projects superior to the plate cribriform plate of ethmoid bone The horizontal plate of the ethmoid bone separating the cranial cavity from the nasal cavity. perpendicular plate of ethmoid bone forms superior part of nasal septum superior nasal concha not a named bone, but part of the ethmoid bone. Above middle nasal concha middle nasal concha of ethmoid bone the middle thin, spongy, bony plate with curved margins, part of the ethmoidal labyrinth, projecting from the lateral wall of the nasal cavity and separating the superior meatus from the middle meatus; sella turcica depression in the sphenoid bone where the pituitary gland is located temporal process arch of bone extending posteriorly from the zygomatic bone nasal bones Bones that form the bridge of the nose. lacrimal bone small fragile bone making up part of the front inner walls of each eye socket and providing room for the passage of the lacrimal ducts vomer bone Flat, thin bone that forms part of the nasal septum Ramus An extension of a bone making an angle with the rest of the structure coronoid process insertion process for the temporalis muscle mandible angle where the body and ramus of the mandible meet mandibular condyle Articulation point of the mandible with the mandibular fossa of the temporal bone mental foramen of mandible bone Its the lateral aspect that allows nerves to pass to the chin and lip. external acoustic meatus Canal leading to eardrum and middle ear lacrimal foramen hole located at the distal end of the lacrimal bone foramen magnum A large opening at the base of the skull through which the brain connects to the spinal cord.
