Bone is composed of fibrous and connective tissue.
 * 1) A bone is an organ composed of what types of tissues? (Be detailed, pictures nice)**

A long bone is encased by fibrous membrane except it is covered at the ends by hyaline cartilage. There may also be some red blood cells underneath.
 * (2) Describe the make up of LONG bone. DESCRIBE**

//**Osteoblasts**:// They form the bones //**Osteocytes**:// They maintain structure of bone. //**Osteoclasts**:// They break down bone.
 * (3) What types of cells are involved in bone growth, remodeling, and repair? DESCRIBE**


 * (4) What are two types of ossification. DESCRIBE.**
 * Intramembranous Ossification** forms from membrane ish layers of primitive //connective tissue//.
 * Endochondral Ossification** begins as hyaline cartilage that is subsequently replaced by bone tissue.


 * (5) What are the four steps required in fracture repair? DESCRIBE.**
 * **//Hematoma//.** After the fracture the bone produces large clots where the.
 * **//Fibrocartilaginous callus//.** Tissue repair begins, and a fibrocartilaginous callus fills the space between the ends of the broken bone
 * **//Bony callus//**. Osteoblasts produce trabeculae like spongy bone then convert the fibrocartilage callus
 * **//Remodeling//.** Osteoblasts build new compact bone at the periphery, then they absorb.

protect the parts of the body, make blood cells, supports the body, and allows our body to live/move
 * (6) What are the functions of the skeleton?**

fibrous, cartilaginous, or synovial.
 * (7) How are joints classified?**


 * (8) Give examples of different types of synovial joints and the movements they permit.**
 * //**Ball-and-sockets joints**//** are located at the hips and the shoulders that allow movement in all planes, even rotational movement. **//**hinge joints**//** //**are**// located at the knee and elbow, which permit movement in one direction only....
