Chapter 7I.Bone StructureA.Bone Classification1.4 Classes Long, go around, flat and irregular2.Example of a long bring up- forearm and thigh finger cymbals.3.Short Bones atomic number 18 shaped like cubes4.Ex. Of short drum atomic number 18 in wrists and ankle ivorys5.Flat oss are placoid structures6.Ex of Flat bones are platelike structures7.Irregular bones vary in size8.Irregular bones vary in size9.Examples of irregular bones are those of the vertebra and some facial bones10.Round bones are also called sesamoid bones i.They are wasted and modular and embedded in tendonsii.Example is the patella (kneecap)B.Parts of a long bone1. An expanded end of a long bone is an epiphysis2.An epiphysis articulates with another bone3.Articular Cartilage is primed(p) on the epiphysis 4.The shaft of a long bone is called a beam5.Periosteum functions t course of instruction and repair bone tissue6.Periosteum is a tough, vascular, fibrous membrane covering the diaphysis of a bone7.Pro cesses grant sites for attachment of tendons or ligaments8.The wall of the diaphysis is composed of jampack bone9.Compact bone has no gaps10.Ephiphysis is composed of spongy bone11. squishy bone consists of bony plates called trabeculae12.A bone is composed of spongy and compact bone13.A canal called the medullary cavity runs through the diaphysis14.The endosteum lines this cavity and spaces of the spongy bone15.Endosteum contains bone forming cells16.The tissue that fills the spaces of the bone is called internality17.&nb... ...ome osteocytes11.Periosteum comes from cells of the primitive conncective tissue that persist outside of the developing bone.12.Compact bone is formed by osteoblasts on the inside of periosteum13.Intramembranous accord is the process if successor connective tissue to form an intramembranous bone.D.Endochondral Bones1.Most of the bones are these types of bone2.They develop as masses of hyaline cartilage3. in conclusion the cartilage decompses forming pe riosteum from connective tissue that encircles that developing structure4.Blood vessels and dedifferentiated connective tissue cells invade the disintegrating tissue5.Some of these cells become osteoblasts6.Ostoeblasts form the spongy bone in the spaces previously housed by cartilage7.Endochondral ossification is the process of forming an endochondral bone by the replacement of hyaline cartilage.
