Frontal Bone
the large cranial bone forming the front part of the cranium: the forehead and the upper part of the orbits
Parietal Bone
either of two skull bones between the frontal and occipital bones and forming the top and sides of the cranium
Temporal Bone
bone that forms parts of the side of the skull and floor of the cranial activity.
Occipital Bone
a saucer-shaped membrane bone that forms the back of the skull
sphenoid bone
bat-shaped bone that is described as the keystone bone in the cranium because it articulates with all other cranial bones
ethmoid bone
contributes to the anterior cranial fossa; forms part of the nasal septum and the nasal cavity; contributes to the medial wall of orbit
Sagittal Suture
Located on the midline of the skull lies between both parietal bones (immovable joint)
Coronal Suture
the suture between the parietal and frontal bones of the skull
Lambdoid Suture
suture that separates parietal bones from occipital bone
Squamous Suture
between parietal bone and temporal bone on side of the skull, bordered in back by occipital bone
supraorbital margin
frontal; thick margin of the eye socket that lies beneath the eyebrows
supraorbital foramen
frontal; opening above each orbit allowing blood vessels and nerves to pass
Glabella
frontal; smooth area between the eyes
zygomatic
cheekbones; each form a lateral orbit
zygomatic process
temporal; a bridgelike projection that articulates with the zygomatic bone to form the zygomatic arch
mandibular fossa
temporal; located on the inferior surface of the zygomatic process; receives the condylar process from of the mandible to form the temporomandibular joint
External acoustic Meatus
temporal; canal leading to the middle ear and eardrum
Styloid Process
temporal; needlelike process that serves as an attachment point for ligaments and muscles of the neck
Jugular Foramen
temporal; located where the petrous part of the temporal bone joins the occipital bone; forms an opening which the internal jugular vein and cranial nerves IX, X, and XI pass
Mastoid Process
temporal; located posterior to the external acoustic meatus; serves as an attachment point for neck muscles
Foramen Magnum
occipital; large opening at the base of the cranium through which the spinal cord passes
Occipital Condyle
occipital; rounded projections lateral to the foramen magnum that articulates with the first cervical vertebra (atlas)
external occipital protuberance
occipital; midline prominence posterior to the foramen magnum
greater wings
sphenoid; project laterally from the sphenoid body, forming parts of the middle cranial fossa and the orbits
pterygoid processes
sphenoid; project inferiorly from the greater wings; attachment site for chewing muscles
Sella turcica
sphenoid; "turkish saddle" located on the superior surface of the body; the seat of the saddle, called the hypophyseal fossa, holds the pituitary gland
lesser wings
sphenoid; form part of the floor of the anterior cranial fossa and part of the orbit
Crista Galli
ethmoid; rooster's comb, a superior projection that attaches to the dura mater, helping to secure the brain within the skull
cribriform plates
ethmoid; located lateral to the crista galli; form a portion of the roof of the nasal cavity and the floor of the anterior cranial fossa
Maxilla
Forms most of the upper jaw, and part of the hard palate, contains upper molars, premolars, and canines
Mandible
the lower jawbone in vertebrates
Condylar Process
mandible; articulate with the mandibular fossae of the temporal bones
body
mandible; horizontal portion that forms the chin
ramus
mandible; vertical extension of the body
mental foramina
paired openings on the body; transmit blood vessels and nerves to lower lip and skin of the chin
Vomer
thin trapezoidal bone of the skull forming the posterior and inferior parts of the nasal septum
