Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. epiphyseal plate –injuries here can result in premature ossification of the plate and lack of bone growth (abnormally short bones) articular cartilage –injuries here can result in damage to the epiphyses of bones and pain in the joints apophysis-the point where a tendon attaches to a bone –can pop loose or chip off, leading to painful rehabilitation Epiphyseal Injuries

Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Acromegaly Excess Growth Hormone in adulthood can lead to thickening of the diaphysis and epiphysis of long bones. Characteristics include unusual hand, shoulder, and jaw size. Do NOT confuse with gigantism which affects overall growth including height and is caused by excess growth hormone in childhood.

Immune system attack causes amenorrhea. 4. Greenstick is a type of fracture. 5. Bursitis is an inflammation of bursae. Review and Assessment
