Document Summary
Irregular bones: make up the vertebral column and some bones of the skull: bones are also categorized by: Firmness: results from inorganic salts (calcium, phosphate) that are laid down in the bone matrix. Rigidity: necessary to keep long bones straight and enables bones to bear weight. Elasticity: flexibility to absorb the force from falls: pathological fractures: fractures caused by weakened bone tissue, joints/articulations: the connections between bones. Classified according to structure and degree of mobility: Bony tissue that forms between the bones provides strength and stability. Found where bones are exposed to constant pressure. Two bony surfaces united by a ligament or membrane. Contiguous bony surfaces are covered by articular cartilage and connceted by ligaments lined with a synovial membrane. E. g. humeral radius and ulna: ligaments: white, shiny, flexible bands of fibrous tissue that bind joints together and connect bones and cartilage. Some have a protective function: tendons: white, glistening, fibrous bands of tissue that connect muscle to bone.
