What are the different tissues working together that make bone?
Bone, cartilage, dense connective tissue, epithelium, various blood forming tissues, adipose tissue, and nervous tissue
What are the functions of the bones/the skeletal system?
Support the soft tissues and provide attachment sites for muscles (body's structural framework), protect many of the body's internal organs, assist skeletal muscles to produce movement of body parts, store and release several minerals (esp. calcium and phosphorus) to help maintain mineral homeostasis.
What is hemopoiesis?
AKA: hematopoeisis; the formation of blood cells; occurs in the red marrow of bones
Diaphysis
Shaft of the long bone
Epiphyses
Ends of the bone that articulate with adjacent bones
Metaphyses
Areas between the epiphysis and diaphysis; includes the epiphyseal plate (growth plate), which is the site of bone elongation in growing bones
Articular cartilage
At the ends of the bone; reduces friction and absorbs shock at freely moveable joints
Periosteum
A connective tissue covering of the surface of the bone which contains osteogenic cells
Osteogenic cells
Promote bone growth in width, assist in fracture repair, help nourish bone tissue; undergo cell division and develop into osteoblasts
Marrow cavity
The space within the diaphysis that contains yellow marrow (adipose)
Endosteum
The lining of the medullary cavity
Bone tissue
AKA osseus tissue; consists of widely separated cells surrounded by large amounts of matrix
4 principal types of bone cells
1. osteogenic cells2. osteoblasts3. osteocytes4. osteoclasts
Osteoblasts
Bone-building cells; promote bone deposition
Osteocytes
Mature bone cells; derived from osteoblasts; maintain bone tissue
