Front 1

Skeleton

Back 1

The body's framework

constructed of cartilage and bone

Front 2

Axial Skeleton

Back 2

Bones that lie around the body's center of gravity

Front 3

Appendicular Skeleton

Back 3

Bones of the limbs, or appendages

Front 4

Compact Bone

Back 4

Smooth and homogenous

Front 5

Spongy Bone

Back 5

composed of trabeculae(bars) of bone and lots of open space.

Front 6

Long Bones

Back 6

longer than they are wide (fingers)
Prodominantly compact bone

Front 7

Short Bones

Back 7

cube shaped
more spongy than compact
ex. tarsals and carpals

Front 8

Flat Bones

Back 8

thin,waferlike layers of compact bone sandwiching a layer of spongy bone
ex.skull

Front 9

Irregular Bones

Back 9

Fall in no other catagory

Front 10

Sesamoid Bones

Back 10

Special types of short bones formed in tendons
ex. patella

Front 11

Worman or Sutural Bones

Back 11

Tiny bones between cranial bones

Front 12

Articular cartilages

Back 12

cover the bone ends at moveable joints

Front 13

Costal Cartilages

Back 13

found connecting ribs to the sternum

Front 14

Laryngeal Cartilages

Back 14

Largely construct the larynx (voicebox)

Front 15

Tracheal and Bronchial Cartilages

Back 15

Reinforce other passageways of the resporatory system

Front 16

Nasal cartilages

Back 16

support the external nose

Front 17

Intervertebral discs

Back 17

seperate and cushion bones of the spine

Front 18

Most Important Skeletal Cartilages

Back 18

1) Articular cartaliges
2) Costal Cartilages
3) Laryngeal
4)tracheal and Bronchial
5) Nasal
6)intervertebral discs
7) cartilage supporting the ear

Front 19

Cartilage tissue

Back 19

primarily of water and is fairly resilient
contain no nerves or blood tissues.

Front 20

Perichondrium

Back 20

dense connective tissue surrounding cartilage
resist distortion
growth and repair

Front 21

Hyaline Cartilage

Back 21

Looks like frosted glass
sturdy support with some give

Front 22

elastic cartilage

Back 22

more flexible than hyaline, tolerates repeated bending
ex. external ear, epiglottis

Front 23

Fibrocartilage

Back 23

Rows of chondrocytes alternating with rows of thick collogen fibers
can withstand heavy compression

Front 24

Axial Skeleton

Back 24

Skull; veterbral column; bony thorax

Front 25

Cranium

Back 25

enclose and protect the fragile brain tissue

Front 26

Skull

Back 26

cranium and facial bones

Front 27

facial bones

Back 27

present the eyes in an anterior position and form the base for the facial muscles

Front 28

Two Major areas of Cranium

Back 28

Cranial Vault; Cranial Floor

Front 29

Cranial Vault (calvaria)

Back 29

Superior,lateral, and posterior walls of skull

Front 30

Carnial Floor (base)

Back 30

Forms skull bottom

Front 31

Frontal Bone

Back 31

Anterior portion of cranium
-forms forhead;superior part of orbit; and floor of anterior cranial floss

Front 32

Parietal Bone

Back 32

posterior to the frontal bone; forms sides of the cranium

Front 33

Occipital Bone

Back 33

Most posterior bone of the cranium

Front 34

Frontal Bone

Back 34

Anterior portion of cranium; forms the forhead;superior part of orbit; and floor of anterial cranial fossa

Front 35

Paranasal sinuses are in what skull bones

Back 35

maxillary, sphenoid, ethmoid, and frontal

Front 36

What to paransasal sinuses do?

Back 36

lighten the facial bones and act as resonanve chambers for speech

Front 37

What sinus is the largest sinus found in the skull?

Back 37

Maxillary sinus
