1. fill in the blank: the growth plate is called the ______________ plate.
2. what are the ends of a long bone called?

a) diaphysis

part c: bone composition

1. bones are made of about –% calcium carbonate and calcium phosphate.

a) 40 - 50%
b) 60 - 70%
c) 80 - 90%

1. fill in the blank: about ____% of bone is protein (cartilage), which provides ____________
2. why is water content (25 - 30%) important for bones? (short answer)

Explanation:

1. Fibrous joints are immovable as they are held together by dense connective tissue.
2. Synovial joints are the most common and freely - movable type, having a synovial cavity and allowing a wide range of motion.
3. The shoulder and hip joints are ball - and - socket joints which allow multi - directional movement.
4. The shaft of a long bone is called the diaphysis.
5. The growth plate is called the epiphyseal plate.
6. The ends of a long bone are called epiphyses.
7. Bones are made of about 60 - 70% calcium carbonate and calcium phosphate.
8. About 30% of bone is protein (cartilage), which provides flexibility.
9. Water content (25 - 30%) in bones is important as it helps in shock absorption, nutrient transport, and maintaining the bone's structure and resilience.

Answer:

1. a) Fibrous
2. c) Synovial
3. ball - and - socket joints
4. b) Diaphysis
5. epiphyseal
6. b) Epiphysis
7. b) 60 - 70%
8. 30
9. Helps in shock absorption, nutrient transport, and maintaining structure and resilience.
