What does the atlas vertebra do?
Supports your head
What does the axis vertebra do?
Forms a pivot for the atlas vertebra to rotate on
Where is the patella?
In front of the knee, small flat bone sort of closer to the thigh than calf

Basically your entire forehead
Parietal bones location?
Top of the head left and right, a tiny bit on the sides and back too
Sagittal suture location?
Top of the head, between parietal bones
Coronal suture location?
Temples up to the end of the frontal bone on top
Lambdoid suture location?
Triangle in the back of the head
Squamous suture location?
On sides of head near parietal bone, connected to coronal suture
Temporal bone location?

Mandibular fossa location?
Tinyyyy little arm on cheekboke right above jaw
Mandibular condyle location?
On the jaw, very top lateral little protrusion
External acoustic meatus location?
Near temporal bone, little tube for ear
Styloid process location?
On temporal bone, Little jut out toward the bottom, really close to mandible
Mastoid process location?
Behind the ear basically. Bottom of skull
How can you identify the temporal bone on a transverse section?
It’s like in the middle part of the coronal base, not the entire thing but like.. lung-shaped. Top-up, theres little holes and they almost meet in the middle
Occipital bone location on a transverse plane?
Top-down, it’s the bottom of the coronal base. Top-up, same area around the hole basically
How does the sphenoid bone look on a transverse plane?
It looks like a bat honestly. But with a little bit above it
Sphenoid body location?
The part that looks like the bat body
Where is the sella turcica?
Its on the sphenoid body, from the side it looks like a saddle, from the top-down it looks like a bat head
Sphenoid wings location?
Greater wings look like actual wings but lesser wing is directly above that, above the ridge
Sphenoid bone from a side view?
In the middle, it’s kind of shaped like a penis with legs
Where are the foramen rotundum?
Topmost holes on sphenoid bone
Where are the foramen ovale?
Middle hold on sphenoid bone
Where are the foramen spinosum?
Bottom holes (3 in a row, not the lines!!) of sphenoid bone
Where is the optic canal?
Bat “eyes” on the sphenoid body
Superior orbital fissure location?
Inner arc of greater wings of sphenoid bone
Ethmoid bone location?
The 2 lines on anterior cranial fossa
Crista galli of the ethmoid bone?
Top middle protrusion of ethmoid bone (posterior view)
Ethmoid air cells location?
Holes next to center of ethmoid bone (both views)
Middle nasal concha location?
2 middle bottom protrusions of ethmoid bone (posterior view)
Orbital plate location?
Somewhat rounded ounded outer edges of ethmoid bone (both views)
Perpendicular plate location?
Base/body of ethmoid bone (posterior view)
Side view of ethmoid air cells?
Hole in middle-front, right above sphenoid sinus
Ethmoid bone side view?
Its like the back of the eye sockets? It has a sharp protrusion upwards behind the frontal sinus
Crista galli side and top views?
Between the 2 lines, or the sharp protrusion behind frontal sinus
Superior nasal concha location? (Transverse plane)
Top little dots in middle
Middle nasal concha location? (Transverse plane)
Middle dots
Inferior nasal concha location? (Transverse plane)
Swirly big blobs in middle
Nasal septum location? (Transverse plane)
Line between all the nasal concha
Maxillae location?
There’s 2, it’s like the front of your face next to the nose and somewhat under the eyes, your top lip too
Transverse plane of maxillae?
Roof of mouth
Maxillary sinus location?
Transverse plane - To the sides of the nasal concha, blob shaped
Side view - Under the eye sockets
Coronal view - Basically combo of those 2
Zygomatic bones location?
2 of them, outer edge of eye sockets and cheekbone
Lacrimal bones location?
2 of them, inside of eye sockets sorta behind nose
Lacrimal fossa location?
Tiny little teardrop shaped part of lacrimal bones
Nasal bones location?
Bridge of nose
Inferior nasal concha location, in a frontal or side view?
Magatama-shaped in the nose hole.
