24

bones in the skull

frontal, parietal, occipital, temporal, sphenoid, ethmoid, maxilla, palatine, zygomatic, lacrimal, nasal, vomer, inferior nasal conchae, mandible

frontal bone (and what classification of bone it is)

flat bone

parietal bone (and what classification of bone it is)

flat bone

occipital bone (and what classification of bone it is)

flat bone

sphenoid bone (and what classification of bone it is)

irregular bone

ethmoid bone in the context of the skull (and what classification of bone it is)

• the white bone inside this eye in the picture

• you can also see the white perpendicular plate of the ethmoid bone in the picture (as well as the vomer)

• irregular bone

maxilla bone (and what classification of bone it is)

irregular bone

palatine bone (and what classification of bone it is)

• also visible in the corner of the eye, right under the ethmoid bone!

• irregular bone

zygomatic bone (and what classification of bone it is)

irregular bone

lacrimal bone (and what classification of bone it is)

• the red bone I am pointing to

• irregular bone

nasal bone (and what classification of bone it is)

flat bone

vomer bone

inferior nasal conchae (and what classification of bone it is)

irregular bone

mandible (and what classification of bone it is)

irregular bone

what is a suture?

immovable joint

official bones that make up the nasal septum

ethmoid (starts from eye but goes around and is visible above the mandible), and vomer

bones of cranium: list

frontal, temporal, occipital, parietal, sphenoid, ethnoid

facial bones: list

maxilla, nasal, zygomatic, lacrimal, palatine, vomer, mandible and inferior nasal conchae

supraorbital foramen (and what it is part of)

part of frontal bone

sagittal suture (and what it is part of)

part of parietal bone

coronal suture (and what it is part of)

between frontal bone and coronal bone

lambdoidal suture (and what it is part of)

between both parietal bones and occipital bone

foramen magnum (and what it is part of)

• in the occipital lobe

• where the spinal cord exits the skull

squamosal suture (and what it is part of)

separates parietal and temporal bone

external auditory meatus (and what it is part of)

part of temporal lobe

zygomatic process (and what it is part of)

the zygomatic bone is really only the front part of your cheek; the zygomatic arch describes where the temporal and zygomatic bone meet in that arch. The zygomatic process is considered part of the temporal bone.

mastoid process (and what it is part of)

behind the styloid process, the temporal bone that goes down

styloid process (and what it is part of)

part of temporal lobe

vomer bone posterior view

sella turcica (and what it is part of)

part of the sphenoid bone

crista galli (and what it is part of)

• this is the posterior view

• part of the ethmoid bone

perpendicular plate (and what it is part of)

• this is the posterior view

• part of the ethmoid bone

describe the nose hole

the ethmoid wraps around the eye; the part you see in the nose is the perpendicular plate of the ethmoid. The continuation to the bottom is vomer bone. The bottom two things that jut out are the inferior nasal conchae. The top two things that jut out are the middle nasal conchae, which are also part of the ethmoid bone.  The nasal bone isn’t even in the hole, it is the bone on top of the hole. You can’t really see the superior nasal concha, but it is also part of the ethmoid bone.

superior and middle nasal conchae (and what it is part of)

• part of the ethmoid bone

• this is the posterior bone

ethmoid bone by itself (and what classification of bone it is)

irregular bone

hard palate

entire roof of mouth

infraorbital foramen (and what it is part of)

part of the maxilla

temporal process (and what it is part of)

part of the zygomatic bone

coronoid process (and what it is part of)

part of the mandible

mandibular condyle (and what it is part of)

• part of the mandible

• behind the coronoid process

mandibular foramen (and what it is part of)

part of the mandible

mental foramen

bones that make up the eye orbit

frontal, sphenoid, palatine, zygomatic, maxilla, lacrimal, ethnoid

optic foramen (and what it is part of)

part of sphenoid bone

sphenoid and ethmoid bone in the context of the skull

• purple is the ethmoid and the yellow is the sphenoid

• ethmoid is visible in the eye, nose, and anterior of skull
