This bone is found on the inside of flat and long bones.  It is lightweight and not very dense. 

spongy bone

100

This bone is part of the axial skeleton.  It is the only bone in the body that does not attach to another bone.  Its primary purpose is anchoring the tongue

hyoid

100

Ossification refers to this process

bone formation

100

These bones cells are mature 

osteocytes

100

This organ system is made up of all the bones in the body and the tissues that connect them.

Skeletal System

200

Place where two bones come together

joint of articulation

200

The pelvic girdle belongs to this division of the skeleton

appendicular

200

Endochondrial ossificaiton uses this tissue for a template

cartilage

200

Mature bone cells live in cave-like structures called 

lacunae

200

Number of bones an adult human has.

Hollow space at the center of a long bone

medullary cavity

300

The spine belongs to this division of the skeleton

axial

300
Intramembranous ossification uses this for a template

connective tissue membrane

300

The job of osteoclasts

breaking down bone

300

Bones store this inorganic material in their matrix

calcium
400

Long bones increase in length at this structure

epiphyseal plate

400

The pectoral girdle is made up of these two boness

scapula and clavicle

400

These types of bones are formed through endochondrial ossification. 

Long bones

400

the job of osteoblasts

building bone

400
Fat is stored in this type of marrow

yellow marrow

500

These are vertical canals through compact bone that allow nerves and blood vessels to pass through 

haversian

500

Phalanges are part of this skeletal division

appendicular

500

These types of bones are formed through intramembranous ossification 

flat bones

500

These bone cells are responsible for forming the medullary cavity.

osteoclasts

500

Red marrow is responsible for making this type of cell.
