Document Summary

Living organisms that change shapes for a reason, they have adapted to the way we move. Axial skeleton protecting vital living systems, different functionally than appendicular. Appendicular skeleton have different actions and different shapes. I. e. the rest; upper extremities (arms, hands), and lower extremities (legs, feet), pelvis. 5 sections: cervical spine (neck, thoracic spine (ribcage, lumbar spine (low back, sacrum (part of pelvis, coccyx (tail bone) Pelvic floor connective tissue and muscle serves as a connection site, makes pelvis less heavy. Functions of the skeleton: attachments for muscles, leverage for applying torque to the joints, protect vital organs (i. e. brain, lungs, heart, support soft tissues, making new red blood cells, reservoir for calcium and phosphate. Observation bone is laid down in areas of high stress, bone is lost in areas of low stress) Use it or lose it the process is called remodeling.
