Amphiarthroses

A slightly movable joint

1

Appendicular skeleton

Bones of the limbs and limb girdles that are attached to the axial skeleton.

2

Articular cartilage

The cartilage covering the articular surfaces of the bones forming a synovial joint.

3

Articulations

Joint; point where two bones meet.

4

Axial skeleton

The bones of the skull, vertebral column, thorax, and sternum

5

Bony thorax

Bones of the thorax, including ribs, sternum, and thoracic vertebrae.

6

Cartilaginous joint

Joints connected entirely by cartilage. Allows more movement between bones than a fibrous joint but less than the highly mobile synovial joint.

7

Compact bone

Dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces that contain the bone cells

8

Diaphysis

The main or midsection (shaft) of a long bone.

9

Pelvic girdle

Incomplete bony basin formed by the two coxal bones that secures the lower limbs to the sacrum of the axial skeleton.

10

Periosteum

Double-layered connective tissue that covers and nourishes the bone

11

Red marrow

Flexible tissue in the interior of bones. Found mostly in the flat bones.

12

Short bones

Bones that are as wide as they are long.

13

Shoulder girdle

Composite of two bones, scapula and clavicle, that attach the upper limb to the axial skeleton; also called the pectoral girdle.

14

Skull

Bony enclosure for the brain.

15

Diarthroses

A freely movable joint.

16

Epiphyseal plate

Area at the long end of a bone that contains growing bone.

17

Epiphysis

The end of a long bone

18

Fibrous joint

Connections between bones that are held together by fibrous connective tissue that includes many collagen fibers

19

Flat bones

Made up of a layer of spongy bone between two thin layers of compact bone. Their shape is flattened, not rounded. Examples include the skill and ribs. Flat bones have marrow, but not a bone marrow cavity.

20

Intervertebral disks

The disks of fibrocartilage between the vertebrae

21

Irregular bones

Classification of bones that refer to the bones that do not fit into the other classifications.

22

Ligaments

Tissue connecting bone to bone

23

Long bones

Bones that are longer in length than in width.

24

Spongy bone

Network of irregularly-shaped sheets and spikes of bone.

25

Synarthroses

An immovable joint

26

Synovial joint

Freely movable joint exhibiting a joint cavity enclosed by an articular (fibrous) capsule lined with synovial membrane.

27

Vertebral column

The spine, formed of a number of individual bones called vertebrae and two composite bones (sacrum and coccyx)

28

Yellow marrow

Bone marrow in which fat cells dominate.
