State the functions of bone
- Support soft tissues
- Protection of internal organs
- Assistance in movement
- Mineral homeostasis (storage of calcium and phosphorus)
- Blood cell production (Red bone marrow)
- Triglyceride storage (yellow bone marrow)
What is the site of blood cell formation?
Red bone marrow
What is yellow bone marrow?
Adipose connective tissue
Where is the epiphyseal plate found?
The metaphysis of a growing bone
What is the articular cartilage of a long bone and what does it cover?
hyaline cartilage; covers the epiphyses
What is dense irregular connective tissue that covers the bone?
Periosteum
What is the marrow cavity?
Space inside the diaphysis
What is endosteum?
Membrane lining the marrow cavity
What is the bone matrix composed of?
- water (25%)
- collagen (25%)
- hydroxyapatite (50%)
What provides the bone its hardness and compression?
Hydroxyapatite
What provides the bone its flexibility and tensile strength?
Collagen
What do osteoblasts secrete?
Bone matrix
What regulates the composition of bone matrix?
Osteocytes
What releases enzymes that digest bone matrix for remodeling of bone?
Osteoclasts
Are osteoblasts and osteocytes mitotic?
No. non-mitotic
What are osteoclasts formed from?
formed by fusion of numerous monocytes
