Skeleton

card image

-the body's framework, composed of cartilage & bone
-in embryos the skeleton is predominantly made up of hyaline cartilage, replaced by more rigid bone.

2

Functions of the skeleton.

card image

-supports and protects the body
-responsible for body movement
-bones store lipid and minerals
-site of hematopoiesis

3

Axial Skeleton

card image

-bones that lie around the body's center of gravity

4

Appendicular Skeleton

card image

-bones of the limbs or appendages

5

Articular cartilage

card image

-covers bone ends at movable joints

6

Costal cartilage

card image

-connects ribs to sternum

7

Laryngeal Cartilage

card image

-constructs the larynx (voice box)

8

Tracheal & Bronchial Cartilage

card image

-reinforce passageways of the respiratory system

9

Nasal Cartilage

card image

-supports the external nose

10

Invertebral Discs

card image

-separates and cushions bones of the spine

11

Perichondrium

card image

-dense connective tissue that surrounds cartilage

12

Hyaline Cartilage

card image

-provides sturdy support with some resilience
-most skeletal cartilage is hyaline cartilage

13

Elastic Cartilage

card image

-more flexible than hyaline cartilage
-located in the external ear and epiglottis

14

Fibrocartilage

card image

-consists of rows of chondrocytes alternating with rows of thick collagen fibers
-great tensile strength, can withstand heavy compression

15

Compact Bone

card image

-smooth and homogenous

16

Spongy Bone

card image

-composed of small bars of bones and lots of open space

17

Long Bones

card image

-much longer than they are wide
-generally consists of a shaft with heads at either end
-predominantly composed of compact bone
-examples: femur & phalanges

18

Short Bones

card image

-typically cube shaped
-contains more spongy bone than compact bone
-example: tarsal and carpals

19

Flat Bones

card image

-generally thin with 2 wafer-like layers of compact bone sandwiching a layer of spongy bone between them
-many flat bones are curved

20

Irregular Bones

card image

-bones that do not fall into any of the categories
-ex: vertebrae

21

Sesamoid Bones

card image

-special types of short bones formed in tendons
-Example: patellas

22

Sutural Bones

card image

-tiny bones between cranial bones

23

Tuberosity

card image

-large rounded projection

24

Crest

card image

-narrow ridge of bone

25

Trochanter

card image

-very large, blunt, irregulary shaped process

26

Line

card image

-narrow ridge of bone; less prominent than a crest

27

Tubercle

card image

- small rounded projection or process

28

Epicondyle

card image

-raised area on or above a condyle

29

Spine

card image

-sharp, slender, often pointed projection

30

Process

-any bony prominence

31

Head

card image

-bony expansion carried on a narrow neck

32

Facet

card image

-smooth, nearly flat articular surface

33

Condyle

card image

-rounded articular projection

34

Ramus

card image

-armlike bar of bone

35

Groove

card image

-furrow

36

Fissure

card image

-narrow, slitlike opening

37

Foramen

card image

-round or oval opening through a bone

38

Notch

card image

-indentation at the edge of a structure

39

Meatus

card image

-canal like passageway

40

Sinus

card image

-bone cavity, filled with air and lined with mucous membrane

41

Fossa

card image

-shallow basin-like depression in a bone

42

Diaphysis

card image

-the shaft of a bone
-composed of compact bone
-has a smooth surface

43

Periosteum

card image

-fibrous membrane covering the bone

44

Perforating Fibers

card image

-fibers of the periosteum that penetrates into the bone

45

Osteoblasts and osteoclasts are found on the inner, or osteogenic layer of the _____________.

Periosteum

46

Epiphysis

card image

-end of the long bong
-composed of a thin layer of compact bone that encloses spongy bone

47

Epiphyseal Plate

card image

-thin area of hyaline cartilage that provides for longitudinal growth of the bone during youth

48

Medullary Cavity

card image

-storage region for adipose tissue, or yellow bone marrow

49

Epiphyseal Lines

card image

barely, discernible remnants

50

Central (Haversian) Canal

card image

-runs parallel to the long axis of the bone
-carries blood vessels, nerves, and lymphatic vessels through the bony matrix

51

Osteons

card image

the central canal and all the concentric lamellae surrounding it

52

Canaliculi

card image

-tiny canals radiating outward from a central canal to the lacunae of the first lamella and then lamella to lamella
-forms dense transportation networks through the hard bone matrix, connecting all the living cells of the osteon to the nutrient supply
