Diaphysis shaft, compact bone
Periosteum a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints
Epiphysis end consisting of thin compact bone enclosing spongy bone
Articular cartilage covers the epiphysis, is hyaline cartilage, prvides smooth slippery surface
Epiphyseal line in adults separating the epiphysis from the diaphysis
Medullary cavity, or yellow marrow stores adipose tissue in adults, is red marrow in infants. Red Marrow is in spongy cavities of flat bones and epiphyses of some long bones in adults

Osteoblasts Addition of calcium Bone growth/remodelling
Osteoclasts Removing of calcium Bone growth/remodelling
Bone salts and Organic matrix Bone salts and Organic matrix
Osteocytes Bone Cells Osteo = Bone Cytes = Cells
Lacunae cavities in the matrix were osteocytes are found
Haversian central) canals are the centers of the lamellae; they carry blood vessels and nerves
Calcium salts in the matrix provide the hardness
collagen fibers provide flexibility and great tensile strength

Fibrous Joints Tissue? Cavity? Movement? Bones united by fibrous tissue no joint cavity Mostly immovable

Cartilaginous Joint Tissue? Cavity? Movement? Connected by Cartilage No joint cavity Slightly movable

Synovial Joint Tissue? Cavity? Movement? Articular cartilage separates, joint cavity Synovial fluids is in cavity Fluid lubricates the joint Very movable

What are the features of a Synovial Joint Articular Cartilage (hyaline cartilage) covers the ends of the bone Joint surfaces are enclosed by a fibrous articular capsule Have a joint cavity filled with synovial fluid Ligaments reinforce the joint
