cranial: temporal

temporal bones and articulations (hold on tight)

temporal bones (2)

the bones inferior to the parietal bones on the lateral skull

the temporal bones have four major regions, what are they?

squamous, tympanic, mastoid, petrous

what region is the lateral surface bordering the squamous suture

squamous

squama

the convex external surface of the region

what is the concave internal surface of the squamous region?

cerebral surface

the cerebral surface’s curvatrues parallel?

the surface of the brain

zygomatic process

the inferior part of the squamous region

the zygomatic process curves?

laterally and anteriorly, meeting the temporal process of the zygomatic bone

the zygomatic processes together form the?

zygomatic arch (cheekbone)

the zygomatic arch defines?

the projection of the cheek

the squamous region abuts (shares a region) with the?

parietal bone on each side

tympanic region

surrounds external acoustic meatus (auditory canal)

the tympanic region is immediately

posterior and lateral to the mandibular fossa

styloid process

needlelike projection (stylus) inferior to the external acoustic meatus

what attachment site does the styloid process mark?

ligaments that support the hyoid bone and muscles of the tongue, pharynx, and larynx

some people regard the land mark of the styloid process and refer it as part of what?

pertrous region

mastoid

breast shaped area that is posterior to the ear

when it comes to the petrous region, what other structure is considered to be apart of this region according to other texts?

mastoid

mastoid process

rough projection that anchors some neck muscles that rotate and extend the head

what is the mot massive portion of the temporal bone that contributes to the cranial base?

petrous region

what region also forms the lateral region of the skull base?

petrous region also

jugular foramen

passageway into the internal jugular vein and CN IX X XI

carotid canal

opens in petrous on the skull’s inferior aspect, passageway for internal carotid artery, anterior to jugular foramen

foramen lacerum

jagged opening between the medial tip of the petrous, (b/t temporal and sphenoid)

What hole is almost completely closed off by cartilage in a living person, but in a dried skull is conspicuous (visible)?

foramen lacerum

what lies in the cranial cavity of the posterior face of the petrous region

internal acoustic meatus

the internal acoustic meatus transmits which cranial nerves?

CN VII and VIII
