| Located on the temporal bone, a very round hole medial and anterior to the styloid process | carotid canal |
| Located on the temporal bone, a very small round hole between the styloid and mastoid process | stylomastoid canal |
| Located on the temporal bone, a process lateral and posterior to the styloid process | mastoid process |
| Located on the underside of the temporal bone, a pointy, tooth-looking process | styloid process |
| Located on the interior of the skull on the temporal bone, a hole on the hearing canal | internal acoustic meatus |
| Where the ears attach on the temporal bone | external acoustic meatus |
| Where the mandible articulates with the skull on the temporal bone | mandibular condyle |
| Located on the temporal bone, a jagged hole posterior and lateral to the carotid canal by the foramen magnum | jugular foramen |
| On the temporal bone, this leads from the zygomatic bone towards the temporal bone | temporal process |
| The arch between the zygomatic process and the temporal process | zygomatic arch |
| On the occipital bone, the large hole where the spinal cord attaches to the brain | foramen magnum |
| On the occipital bone, the knobby things on either side of the foramen magnum | occipital condyle |
| The concave larger wing of the sphenoid bone | greater wing |
| The wing superior to the greater wing of the sphenoid bone | lesser wing |
| On the sphenoid bone (superior view), an indent akin to a horse's saddle in the middle of the structure | sella turcica |
| From posterior view of sphenoid bone, two plates on both sides of inferior portion of sphenoid bone | medial and lateral pterygoid plates |
| Located on the sphenoid bone, two very round holes superior to the sella turcica | optic foramen (optic canal) |
| Located on the sphenoid bone, holes posterior and lateral to the optic foramen | foramen rotundum (R) |
| Located on the sphenoid bone, larger holes posterior and lateral to foramen rotundum | foramen ovale (O) |
| Located on the sphenoid bone, very round small holes posterior and lateral to foramen ovale | foramen spinosum (S) |
| Elongated space between sphenoid bone and ear canal | foramen lacerum |
| Opening directly inferior to lesser wing of sphenoid bone | superior orbital fissure |
| Opening posterior to the orbital opening (on floor of orbital socket) of sphenoid bone | inferior orbital fissure |
| The "clit" on the interior part of the skull of the ethmoid bone | cribiform plate |
| The humpy piece in the middle of the "clit" of the ethmoid bone | crista galli |
| Little holes on the surface of the "clit" of the ethmoid bone | olfactory foramina |
| On anterior view, the air channels on the ethmoid bone | ethmoid air cells |
| Plate in the medial portion of the ethmoid bone | perpendicular plate |
| Anterior and lateral to the perpendicular plate of ethmoid bone | superior nasal conchae |
| Inferior to the superior nasal concha of the ethmoid bone | middle nasal conchae |
| Smooth sides (plates) of ethmoid bone | orbital plate |
| Holes found on anterior frontal bone | supraorbital foramen |
| Of the facial bones, this is superior to the teeth and holds the teeth in place | Maxiilla (paired) |
| Of the facial bones, these are the holes that are inferior to the eyes | Infraorbital foramen |
| Of the facial bones, these are the little "mountains" between the teeth sockets | alveolar processes |
| Of the facial bones, this is the hole posterior to the two front teeth (inside of mouth) | incisive foramen |
| Of the facial bones, this is the anterior portion of the roof of the mouth | palatine process (makes up anterior 2/3 of the hard palate - the rest is made-up of palatine bones) |
| Of the facial bones, the holes on the posterior side of the roof of the mouth | greater palatine foramen |
| Of the facial bones, the part leading from the zygomatic bone towards the temporal bone | temporal process |
| Of the facial bones, the arch between the zygomatic process and the temporal process | zygomatic arch |
| Of the facial bones, the two holes lateral on either side of the nasal bone | lacrimal foramen |
| Of the facial bones, this bone is superior to the nasal opening | nasal bone (paired) |
| Of the facial bones, the lowest protrusions in the nasal opening | inferior nasal conchae (there are three pairs of nasal conchae; the superior and middle pairs are part of the ethmoid bone. The inferior pair is considered separate bones) |
| Of the facial bones, this bone is in the middle of the nasal opening | perpendicular plate |
| Of the facial bones, this bone is part of the ethmoid bone and is the inferior portion of the nasal septum | the vomer |
| Of the facial bones, these are the "little mounds" in between the teeth sockets | alveolar processes |
| Of the facial bones, the holes on the side of the chin | mental foramen |
| Of the facial bones, the holes on the interior portion of the mandible | mandibular foramen |
| Of the facial bones, the point of articulation of the mandible with the temporal bone | mandibular condyle |
| Of the facial bones, the process anterior to the mandibular condyle | coronoid process |
| What bones make-up the axial skeleton? | Consists of 80 bones Skull Hyoid bone Vertebrae Sternum Ribs |
