Question 1

Skeletal system functions

Answer 1

1. Supports
2. Protections
3. Movement
4. Storage (Calcium and phosphorus)
5. Blood cell production

Question 2

Cartilage

Answer 2

• Firm smooth, resilient, non-vascular connective tissue

• Find in the joints of the body
• Forms articular cartilage for joints, nose etc.

Question 4

Fibrocartilage

Answer 4

• Strongest of all due to orientation and density
• Found in areas that require lots of support such as intervertebral disk.

Question 5
