sphenoid
inferior to frontal bone; wings greater and lesser
FOSSA
A DEPRESSION; MAY BE SHALLOW OR DEEP(SOME ARE SITES FOR ATTACHMENT)
ORBITS
LATERAL TO NASAL BONE
ethmoid bone
a single midline cranial bone of the skull. It articulates with the frontal, sphenoid, lacrimal, and maxillary bones and adjoins the vomer at its inferior and posterior border
SUPRAORBITAL FORAMEN
OPENING ABOVE THE EYE; ONE ON EACH SIDE
squamous suture
separates the temporal bone on the left and right and the parietal bone
angle of the mandible
where the body and the ramus meet
INFERIOR MIDLINE
NASAL BONES LEFT AND RIGHT PARTS
hypoglossal canal
openings anterior and lateral to the foramen magnum are visible on the inferior view of the occipital bone
naming of ligaments starts with origin
ex; spheno-mandibular-ligament
(sphenoid connects to mandibular)
mastoid process
posterior to the external auditory canal, is a large roughened projection, composed of air spaces that communicate with the middle ear cavity
PERIFORM APPETURE
INFERIOR TO ORBITS IS A BONY OPENING
temporal lines;superior temporal line, inferior temporal line
two separate parallel ridges on the lateral surface of the skull that cross both the frontal and parietal bones;
styloid process
inferior and medial to the external auditory canal is a long pointed bony projection that serves as an attachment for muscle and ligament attachment
temporal bone
immediately posterior to sphenoid and inferior to parietal; also a paired bone
what does the optic canal contain
the optic nerve
SAGITTAL PLANE
RUNS VERTICALLY THROUGH THE BODY;CUTS INTO LEFT AND RIGHT PORTIONS
maxilla
inferior and anterior this starts lateral to nasal bones and makes up the upper jaw
NASAL CONCHAE
3 PAIRS OF BONE ON THE LATERAL WALL OF THE NASAL CAVITY
foramen lacerum

occipital bone
inferior and posterior bone of the cranium
INFRAORBITAL FORAMEN
INFERIOR TO THE NASAL CAVITY, LATERALLY THERE ARE TWO OPENINGS
cribriform plates
horizontal bone that is crossed by the perpindicular plate.it is visible from the inside of the cranial cavity and present on the superior aspect of the bone, allow sense of smell
tympanic portion
