The bridge of the skull. Bridging the cheekbone (zygomatic bone) and depressed bone (temporal bone)
38
What and where is the external auditory meatus?
BONE EARS. In between the blade (mastoid process) and the bridge (zygomatic process)
39
What are the four types of teeth?
Incisors, canines, premolars, and molars Human dental formula: 2-1-2-3 (top and bottom)
40
What is the only floating bone in the body?
Hyoid bone. It looks like a little fish jaw.
41
Sternum
Holds the rib cage shut
42
How many ribs are there?
12 pairs of ribs. 7 pairs are true ribs (direct connection to sternum) 5 pairs are false ribs - 3 ribs piggyback off rib 7 to the sternum - 2 ribs don't connect to vertebra
43
What are the bones in the vertebrae?
Superior to inferior: - 7 Cervical (baby holes) - 12 Thoracic (glory hole with handles) - 5 Lumbar (big plate) - 1 Sacrum (connects MISSINGNO (innominates)) - 1 Coccyx (tailbone)
44
What are some characteristics of the cervical vertebrae?
It has baby holes, like someone hammered in some nails and took them out.
45
What are some characteristics of the thoracic vertabrae?
It has a gloryhole with handles
46
What are some characteristics of the lumbar vertebrae?
It has a big plate that would work well as an oil lamp
