Skeletal System

periosteum

outermost layer of the bone, made up of fibrous tissue

2
Skeletal System

compact bone

dense, hard layers of bone tissue that lie underneath the periosteum

3
Skeletal System

cancellous (spongy) bone

contains little spaces like a sponge and is encased in the layers of compact bones

4
Skeletal System

endosteum

membranous lining of the hollow cavity of the bone

5
Skeletal System

diaphysis

shaft of the long bones

6
Skeletal System

epiphysis (pl. epiphyses)

end of each long bone

7
Skeletal System

bone marrow

material found in the cavities of the bones

8
Skeletal System

red marrow

thick, bloodlike material found in flat bones and the ends of long bones; location of blood cell formaiton

15
Skeletal System

lumbar vertebrae (L1 to L5)

third set of five larger vertebrae, which form the inward curve of the spine

16
Skeletal System

sacrum

next five vertebrae, which fuse together to form a triangular bone positioned between the two hip bones

Skeletal System

coccyx

four vertebrae fused together to form the tailbone

lamina (pl. laminae)

part of the vertebral arch

19

sternum

breastbone

23
Skeletal System

xiphoid process

lower portion of the sternum

24
Skeletal System

humerus

upper arm bone

25
Skeletal System

ulna and radius

lower arm bones

26
Skeletal System

olecranon process

projection at the upper end of the ulnathat forms the the bony point of the elbow
