D.r:Khalid Ayman Elmorshedy INTENDED LEARNING OUTCOMES At the end of the lecture, the students should be able to: Enumerate the functions of bone Classify bones according to shape, structure & development Enumerate the bones of axial and their functions BONE Definition of bone: FUNCTIONS OF BONE 1. Support: 2. Protection: 3. Levers: 4. Mineral Storage: 5. Blood Cell Formation (Hematopoiesis): 6. Body weight transmission: 7. Joint formation: HUMAN SKELETON It consists of 206 bones. It can be studied in 2 parts: A- Exoskeleton: B- Endoskelton: 1- Axial skeleton 2- Appendicular skeleton 1- AXIAL SKELETON It consists of 80 bones Consists of the following bones: 2- APPENDICULAR SKELETON Consists of the (126): Upper Extremity (64) Lower Extremity (62) CLASSIFICATIONS OF BONES 1- According to the microscopic structure: CLASSIFICATIONS OF BONES 2- According to development (bone formation) (ossification): 1. Membranous 2. Cartilagenous CLASSIFICATIONS OF BONES 3- According to the shape of bones : Long bones Short bones Flat bones Irregular bones Sesamoid bones Pneumatic bones CLASSIFICATIONS OF BONES According to bone marrow: Red. Yellow. Gross Anatomy of Long Bone (structure of long bones) Don’t forget: 1. Diaphysis 2. Epiphysis 3. Periosteum 4. Medullary cavity 5. Articular cartilage MAJOR BONES OF SKELETON SKULL It is made up of 22 bones and 6 ear ossicles: Paired bones Unpaired bones Enumerate them Enumerate them Bones of middle ear cavity Enumerate them VERTEBRAL COLUMN It is made up of 33 vertebrae, namely, 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 coccygeal vertebrae. THORACIC CAGE It consists of 12 thoracic vertebrae, 12 pairs of ribs with their costal cartilages, sternum and xiphoid process.
