Facial & Cranial Bones

the large cranial bone forming the front part of the cranium: the forehead and the upper part of the orbits

either of two skull bones between the frontal and occipital bones and forming the top and sides of the cranium

bone that forms parts of the side of the skull and floor of the cranial activity.

a saucer-shaped membrane bone that forms the back of the skull

bat-shaped bone that is described as the keystone bone in the cranium because it articulates with all other cranial bones

contributes to the anterior cranial fossa; forms part of the nasal septum and the nasal cavity; contributes to the medial wall of orbit

Located on the midline of the skull lies between both parietal bones (immovable joint)

the suture between the parietal and frontal bones of the skull

suture that separates parietal bones from occipital bone

between parietal bone and temporal bone on side of the skull, bordered in back by occipital bone

frontal; thick margin of the eye socket that lies beneath the eyebrows

frontal; opening above each orbit allowing blood vessels and nerves to pass

frontal; smooth area between the eyes

cheekbones; each form a lateral orbit

temporal; a bridgelike projection that articulates with the zygomatic bone to form the zygomatic arch

temporal; located on the inferior surface of the zygomatic process; receives the condylar process from of the mandible to form the temporomandibular joint

temporal; canal leading to the middle ear and eardrum

temporal; needlelike process that serves as an attachment point for ligaments and muscles of the neck

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

temporal; located posterior to the external acoustic meatus; serves as an attachment point for neck muscles

occipital; large opening at the base of the cranium through which the spinal cord passes

occipital; rounded projections lateral to the foramen magnum that articulates with the first cervical vertebra (atlas)

occipital; midline prominence posterior to the foramen magnum

sphenoid; project laterally from the sphenoid body, forming parts of the middle cranial fossa and the orbits

sphenoid; project inferiorly from the greater wings; attachment site for chewing muscles

sphenoid; "turkish saddle" located on the superior surface of the body; the seat of the saddle, called the hypophyseal fossa, holds the pituitary gland

sphenoid; form part of the floor of the anterior cranial fossa and part of the orbit

ethmoid; rooster's comb, a superior projection that attaches to the dura mater, helping to secure the brain within the skull

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

Forms most of the upper jaw, and part of the hard palate, contains upper molars, premolars, and canines

the lower jawbone in vertebrates

mandible; articulate with the mandibular fossae of the temporal bones

mandible; horizontal portion that forms the chin

mandible; vertical extension of the body

paired openings on the body; transmit blood vessels and nerves to lower lip and skin of the chin

thin trapezoidal bone of the skull forming the posterior and inferior parts of the nasal septum
