Question 17

Frontal bone (orbits/eye socket)

Answer 17

Superior wall (superior portion of the eye socket)

Question 18

Ethmoid and lacrimal bones (orbits/eye socket)

Question 19

Zygomatic and Sphenoid (orbits/eye socket)

Answer 19

Lateral wall

Question 20

Maxilla

Answer 20

inferior wall (floor of the orbit very thin)

Question 21

Sphenoid

Answer 21

Base at the apex of the orbit (deepest part of the orbit)

Question 22

Superior Orbital Fissure: Cranial Nerves

Answer 22

Cranial Nerves III (3), IV (4), V1 (5), VI (6)

Question 23

Superior Orbital Fissure
Ophthalmic Vein (superior

Answer 23

Drains muscles of extra-occular movement

Question 24

Superior Orbital Fissure Location

Answer 24

Between the greater and lesser wings of the Sphenoid

Question 25

Inferior Orbital Fissure:Nerves

Answer 25

Branches of V2 | -Specific nerves Infraorbital and zygomatic nerves

Question 26

Inferior Orbital Fissure :carries

Answer 26

Infraorbital artery and inferior ophthalmic vein

Question 27

Inferior Orbital Fissure: Location

Answer 27

Between greater wing f sphenoid and maxilla

Question 28

Optic Canal transmits what

Answer 28

Cranial nerve II and Ophthalmic artery

Question 29

Optic Canal: Location

Answer 29

Within the lesser wing of sphenoid (completely housed in the lesser wing)

Question 30

Infraorbital foramen: Location (not in orbit)

Answer 30

Maxilla (just below the inferior rim of the orbit)

Question 31

Infraorbital foramen transmits (not in orbit)

Answer 31

``` Infraorbital nerve (nerves give off branches and then the name changes) -Direct continuation of V2 (started off as V2 and then branches and becomes the infraorbital nerve) ```

Question 32

Nasal Cavity

Answer 32

Piriform aerature

Question 33

Piriform aperture

Answer 33

bony rim of the nasal cavity (make the shape of your nose)

Question 34

Piriform Aperature bounded by

Answer 34

Nasal bones superiorly | Maxillae create lateral and inferior walls

Question 35

Nasal Septum is composed of

Answer 35

Ethmoid (anterior and superior) Vomer (posterior and inferior) Nasal septum cartilage

Question 36

Nasal Conchae

Answer 36

paired projection

Question 37

Nasal Conchae | Inferior pair

Answer 37

Largest (largest and middle only visible from the anterior)

Question 38

Nasal Conchae | Middle and superior pairs

Answer 38

Projections of ethmoid (middle and inferior pair only visible from the anterior)

Question 39

Nasal conchae | Inferior pairs

Answer 39

smallest are individual bones

Question 40

Nasal Conchae smallest to largest

Answer 40

Inferior pair = largest Middle and Superior pairs = smaller Inferior pair = smallest
