what are the features of the frontal bone?
• frontal sinus - supraorbital foramen/notch
what are the features of the occipital bone?
• foramen magnum • occipital condyles • external occipital protuberance • hypoglossal canal • jugular foramen
• located on the most anterior portion of the cranium - referred to as the forehead
frontal bone
-on the most posterior and inferior aspect of the cranium
occipital bone
what are the features of the temporal bone?
• zygomatic process • mastoid process • styloid process • stylomastoid foramen • mandibular fossa • external acoustic meatus/canal • internal acoustic meatus/canal • carotid canal
• located on the lateral sides of the cranium - separated form the parietal bones and sphenoid bones by the sqaumous suture
temporal bones
what are the features of the sphenoid bone?
• sphenoid sinus • sella turcica • hypophyseal fossa • optic canals • clinoid process • superior orbital fissure • inferior orbital fissure • foramen rotundum • foramen ovale • foramen spinosum • foramen lacerum
• bat-like shaped bone within the cranium • a small part of it can be viewed on the external cranium–between the temporal bone and frontal bone on the lateral side of the cranium
sphenoid bone
what are the features of the ethmoid bone?
• ethmoid sinus • crista galli • cribiform plate • perpendicular plate • nasal conchae (superior and middle)
can be found within the nasal cavity as well as inside the cranial cavity
ethmoid bone
located along the midline, in the most anterior aspect of the frontal bone, just superior to the nose
frontal sinus of the frontal bone
two holes located just superior to the orbit (eyesocket)
supraorbital foramen/notch of the frontal bone
• two of them • located posterior to the frontal bone • separated by sagittal suture
parietal bones
the largest hole in the base of the skull and serves as a passageway for the brain stem
foramen magnum of the occipital bone
two smooth, rounded bumps located immediately lateral on both sides of the foramen magnum
occipital condyles of the occipital bone
• bump located on the posterior side of the cranium, just superior to the base of the skull • level with your ears
external occipital protuberance of the occipital bone
just superior to the lateral sides of the foramen magnum
hypoglossal canals of the occipital bone
• larger holes superior to the hypoglossal canals - jelly bean shaped
jugular foramen of the occipital bone
• on the anterior side of the temporal bone - contributes to the zygomatic arch
zygomatic process of the temporal bone
• posterior to the external acoustic meatus • rounded protrusion that extends inferiorly off the posterior temporal bone • looks like a thumb
mastoid process of the temporal bone
• located just medial to the mastoid process on the inferior aspect of the skull • a long skinny and pointed projection off of the inferior temporal bone • looks like a stylus
styloid process of the temporal bone
located between the mastoid process and the styloid process
stylomastoid foramen of the temporal bone
the smooth indentation located just anterior to the external acoustic canal
mandibular fossa of the temporal bone
• on the external side of the temporal bone - located just posterior to the temporomandibular joint
external acoustic meatus/canal of the temporal bone
