Bio 253 lab (Test 3) Questions and Answers
Verified by Experts
occipital bone posterior head, base of the skull
sphenoid bone "keystone" of the cranium floor/ articulates with other bones
ethmoid bone forms part of the posterior portion of the nose, the orbit, and the floor of
the cranium (nasal cavity)
facial bones are: nasal, lacrimal, palatine, and inferior nasal conche, vomer, maxillae, etc.
nasal bone forms the bridge of the nose
lacrimal bone medial wall of orbit (smallest bones on face)
palatine bone posterior part of hard palate/ lateral nasal cavity
inferior nasal conche inferior wall of nasal cavity
cleft plate/lip lack of fusion of palatine and maxillary bone
vomer bone forms the base for the nasal septum
maxillae bone upper jaw/ articulates with bones of face

Verified by Experts
zygomatic bone cheeks and cheekbones
mandible (jaw) only movable bone of the skull/ largest and strongest facial bone
(temporal-mandible joint)
TMJ syndrome dysfunction of the temporomandibular joint
nasal septum Divides the nasal cavity into left and right portions
deviated nasal septum lateral deflection of the septum from the midline, usually resulting
from improper fusion of septal bones and cartilage
orbits (eye sockets) -Contain the eyeballs and associated structures are formed by seven
bones of the skull
-Five important foramina are associated with each orbit
Hyoid Bone - a U-shaped bone in the neck that supports the tongue.
- doesnt articulate with any bone
- lesser and greater horn
spine 33 bones/ vertebrae (held together by ligaments)
cartilaginous discs btw bones
Spine - cervical 7
