- )Support
- )Movement
- )protection
- )produce blood cells
- ) storage of minerals

206
List the groups of bones that make up the Appendicular Skeletal.
Appendicular: 4 bones in shoulder 6 bones in arms and forearm 58 bones in hands 8 bones in the legs 56 bones in the feet 2 pelvic bones
List the groups of bones that make up the: Axial Skeletal.
29 bones in the head
25 bones of the thorax
26 bones in the vertebral column
Explain the process of conversion of cartilage to bone and when this occurs.
This process is called intramembranous ossification: occurs when a cartilage intermediate is formed and replaced by bone cells- a process called endochondral ossification.
Which minerals are stored in bone?
Calcium and phosphorus
Explain how and where minerals are stored in the bone?
The minerals are stored in the bone matrix. Protein Collagen makes the soft framework where minerals are stored to make bone hard.
what is tendon?
structure of connective tissue that attaches muscle to bone.
What is ligament?
A short band of tough structure of connective tissue that attaches bone to bone.
What are the 2 types of marrow bones and what are their functions?
Red bone marrow:produces all red blood cells and platelets in people.
Yellow Bone marrow: stores fat
What are two types of bone tissue and where is each found?
Compact: cortical found outside
Spongy: Cancellous, inside
What activity helps the bone grow in thickness?
Appositional growth: increase in diameter of bones by the addition of bone tissue on bone’s surface.
what is the epiphysis?
epiphysis is the rounded end of a long bone.
what is the metaphysis?
transitional zone that holds the growth plate
what is the diaphysis?
shaft of a long bone
