1. Explain how and when bone is remodeled. Include the cells and hormones involved in the process.
• Bone remodeling is essentially a lifelong process. The mature bone tissue is removed and replaced the new bone tissue. This promotes healthy bones and can also reshape the bones from injuries like fractures. Osteoblasts secrete new bone tissue while osteoclasts break down the old bone tissues. The body signals the correct amount of growth through parathyroid and growth hormones as well as vitamin D, steroids, and calcitonin.
2. Compare and contrast bone growth and remodeling.
• Bone growth is the increase in length in the long bones. Bone growth occurs during childhood and adolescents. This process uses osteoblasts and

One of them is called a stressed fracture which is caused by trauma that is done to the bone. Another is called pathological fractures which is from the bone weakening due to bone disease
4. Describe the process and list the sequential order of bone healing.
• Reactive-Soon after the fracture or break blood vessels begin to constrict stopping the bleeding. Next a blood clot is formed which is called a hematoma. The blood cells in the blood clot and some of the surround area die and begin to break down. Fibroblasts survive in this area and begin to produce. Osteoclasts absorb the old bone.
• Reparative-Days after the fracture periosteum transform causing the osteoblasts to produce woven bone. This forms with the fibroblasts which forms hyaline cartilage and connects the two sides of the fracture. The gap is bridged and strength is gained. Hyaline cartilage is replaced by lamellar bone, some of the woven bone remains. The hyaline cartilage contains micro vessels and multiple osteoblasts. Hyaline cartilage is the replaced by trabecular bone and most of the original strength is

8. Define the axial and appendicular skeletons.
• The axial skeleton is central area of all the bones such as the ribs, vertebrae, and skull.
• The appendicular skeleton is classified of all the limbs in the body such as your legs and arms.
9. Define the structural and functional classifications of joints and be able to identify these joints on the human
