kyphosis (hunchback) humped curvature in the thoracic spine.
lordodsis (swayback) exaggerated inward (anterior) curvature in the lumbar spine.
rheumatoid arthritis autoimmune disease that affects the connective tissue and joints, causing pain, swelling, and deformation.
arthritis inflammation of one or more joints.
osteoarthritis degenerative that occurs with aging as articular cartilage erodes.
osteoporosis loss of bone mass with resulting structural deterioration of bone tissue.
gout acute inflammation of a joint due to the deposition of uric acid crystals in the joint. This commonly affects the big toe.
rickets bones become soft and deformed due to a lack of vitamin D.
osteosarcoma bone cancer.
5 purposes of bone levers, framework/support, protection, storage (calcium), production (red blood cells).
5 categories of bone long, short, flat, irregular (ears/facial), sesamoid (formed in a tendon near a joint - patella).
lovers fracture
components of skeletal system bones, joints, muscles, ligaments (holds bone together), cartilage (prevent bone on bone, tough shiny smooth substance), tendons (connects muscle to bone).
