Chapter 8 - Axial Skeleton Flashcards
1
Q
skull
frontal bone
A
forms forehead and part of the root of the cranium
2
Q
skull
parietal bone
A
form most of cranial roof and part of its lateral walls
3
Q
skull
temporal bones
A
form lateral walls and part of floor of cranial cavity
4
Q
skull
occipital bone
A
forms rear and base of skull
5
Q
skull
sphenoid bone
A
(temple)
keystone bone of the skull
6
Q
skull
ethmoid bone
A
located between etes, contributes to medial wall of orbit, walls and roof of nasal cavity, and nasal septum
7
Q
skull
skull cavities
A
cranial cavity
obital cavity
oral cavity
nasal cavity
paranasal sinuses
8
Q
function of facial bones
A
- provide shape to each individual’s face
- form part of the orbit and nasal cavity
- support teeth
- attachament of muscles involved in facial expression and chewing
9
Q
lacrimal bones (2)
A
- form part of medial wall of orbits
- tear production = lacrima means tears
10
Q
nasal bones
A
- most anterior portion of the facial area
- forms the bridge of the nose, tip is cartilage
- most commonly fractured facial bone
11
Q
inferior nasal conchae
A
- located inside the nasal cavity
- creates turbulence in inhaled air, helps warm the air
12
Q
vomer
A
- articulates with the maxilla and the ethmoid bone
- forms the nasal septum with the ethmoid bone
13
Q
mandible
A
- forms entire lower jaw
- supports teeth and muscles for mastication (chewing)
mandible and the temporal bone form a joint called the temporomandibular joint (TMJ) - allows us to move our jaw when we talk/chew
14
Q
zygomatic (2)
A
cheekbones
found between the maxilla and temporal bones
15
Q
maxilla (2)
A
- keystone of the facial bones
- form upper jaw, inferior orbit area, and support teeth
