1.02 Remember the structures of the skeletal system Warm up http://www.youtube.com/watch?v=e54 m6XOpRgU http://www.youtube.com/watch?v=abg JD054sds What do you know? Write down the first 5 things that come to mind when you think of the skeletal system 1.02 Remember the structures of the skeletal system Essential Standards: • What is the process of bone formation? • What are the structures of the long bones? • What are the structures of the skeletal system? 1.02 Remember the structures of the skeletal system 4 Bone formation Identify the osteocytes. Osteo = bone Cyte = cell Microscopic mature bone cells 1.02 Remember the structures of the skeletal system 5 Bone formation Ossification – new minerals deposit to form bone Discuss the process of ossification? How do we know ossification occurs? Example 1.02 Remember the structures of the skeletal system 6 Bone formation Ossification – Minerals replace previously formed cartilage. Infants bones are soft and pliable because of incomplete ossification. As bones ossify, they become hard. 1.02 Remember the structures of the skeletal system 7 Bone formation How do we know ossification occurs? Long bones grow in length and ossify from the center to the ends. Give examples of ossification. 1.02 Remember the structures of the skeletal system 8 Bone formation 1.02 Remember the structures of the skeletal system 9 Bone formation 1.02 Remember the structures of the skeletal system 10 Types of Bones Discuss their possible function based on appearance. 1.02 Remember the structures of the skeletal system 11 Types of Bones Long bones • Found in the arms and legs 1.02 Remember the structures of the skeletal system 12 Types of Bones Flat bones • Bones of the skull • Ribs 1.02 Remember the structures of the skeletal system 13 Types of Bones Irregular bones • Spinal column 1.02 Remember the structures of the skeletal system 14 Types of Bones Short bones • Wrist 1.02 Remember the structures of the skeletal system 15 Structures of long bones Identify structures of the long bones. Compare spongy bone to compact bone. 1.02 Remember the structures of the skeletal system 16 Structure of the long bones Compare structures of the long bones. Discuss the importance of having both types of bone tissue. 1.02 Remember the structures of the skeletal system 17 Processing Read pages 157-165 Worksheets 1 and 2 Day 2 Warm up On your vocabulary list, mark the words as followed: Green- Words I know Yellow- Words I sort of know Red- Words I have no idea what it means Axial Skeleton The axial skeleton is blue Includes- thorax, spinal column and skull. Located in the center of the body. 1.02 Remember the structures of the skeletal system 20 Axial Skeleton Ribs- 12 pairs Ribs and sternum (breastbone) Ribs-1-7 true ribs 8-10 False ribs- attached to cartlidge Of the rib above. Floating ribs- 2- No anterior attachment Axial Skeleton Skull frontal view Identify the structures of the frontal view of the skull. 1.02 Remember the structures of the skeletal system 22 Axial Skeleton Skull lateral view Identify the structures of the lateral view of the skull. 1.02 Remember the structures of the skeletal system 23 Axial Skeleton Skull superior view 1.02 Remember the structures of the skeletal system 24 Axial Skeleton Skull lateral view 1.02 Remember the structures of the skeletal system 25 Axial Skelton Hyoid Bone What is unique about the hyoid bone? It is not attached to any other bone. Located above the Adams Apple 1.02 Remember the structures of the skeletal system 26 Axial Skeleton Spinal column Vertebral Structure Identify the structures of the spinal vertebra. 1.02 Remember the structures of the skeletal system 27 Axial Skeleton Spinal column Cervical- supports skull 7 Vertebrae-C1C7 Thoracic- Protects vital organs- 12 T1T12 Lumbar- Lower backSupport 5 Vertebrae- L1-L5 Sacrum- 5 fused vertebrae Coccyx- Tailbone- 3-5 fused bones 1.02 Remember the structures of the skeletal system 28 Axial Skeleton Spinal column Identify the vertebrae in this x-ray. 1.02 Remember the structures of the skeletal system 29 Appendicular Skeleton The appendicular skeleton is beige Arms, legs shoulder girdle and pelvis. 1.02 Remember the structures of the skeletal system 30 Appendicular Skeleton Shoulder girdle Clavicle (collarbone) and scapula (shoulder blade) 1.02 Remember the structures of the skeletal system 31 Appendicular Skeleton Shoulder girdle Identify the structures of the shoulder girdle and upper extremities. 1.02 Remember the structures of the skeletal system 32 Appendicular Skeleton Pelvic girdle Identify the structures of the pelvic girdle and lower extremities. 1.02 Remember the structures of the skeletal system 33 Appendicular Skeleton Pelvis Sacrum, Ilium, Ischium and Pubis Attached together by cartilidge 1.02 Remember the structures of the skeletal system 35 Appendicular Skeleton Pelvic girdle Identify the structures of the pelvic girdle and lower extremities. 1.02 Remember the structures of the skeletal system 36 Appendicular Skeleton Pelvic girdle Compare the male and female pelvis. 1.02 Remember the structures of the skeletal system Copyright Pearson Education, Inc. 37 Processing Finish labeling worksheets 1,2 and 3cut out and glue in notebooks Skeletal System Quiz Study bones for quiz tomorrow Test corrections Warm-up Bone Quiz Joints: Diarthroses 1.02 Remember the structures of the skeletal system 40 Joints- take notes in notebook Diarthroses = moveable joints Four types Ball and socket Hinge Pivot Gliding 1.02 Remember the structures of the skeletal system 41 Joints Ball and socket One bone has a ball at one end The other has a concave socket Allows for the greatest range of motion Ex: shoulder and hip 1.02 Remember the structures of the skeletal system 42 Joints: Diarthroses Example of a ball and socket joint. 1.02 Remember the structures of the skeletal system 43 Joints Hinge joint Move in one direction 1.02 Remember the structures of the skeletal system 44 Joints: Diarthroses Example of a hinge joint. Elbow, knee 1.02 Remember the structures of the skeletal system 45 Joints Pivot joints Bones that rotate across each other Examples- finger joints, wrist and elbow 1.02 Remember the structures of the skeletal system 46 Joints: Diarthroses Identify the pivot joints in this x-ray. Identify other pivot joints. 1.02 Remember the structures of the skeletal system 47 Joints Gliding joint Bones with flat surfaces that slide across each other 1.02 Remember the structures of the skeletal system 48 Joints Example of gliding joint Carpals and tarsals. Where are these located? 1.02 Remember the structures of the skeletal system 49 Joints Amphiarthroses Partially movable joints 1.02 Remember the structures of the skeletal system 50 Joints Synarthroses Immovable joints Connected by fibrous connective tissue Examples- sutures in the skull that are fused. 1.02 Remember the structures of the skeletal system 51 Bursa and Synovial Membrane Bursa Fluid-filled sac that is lined with the synovial membrane 1.02 Remember the structures of the skeletal system 52 Bursa and Synovial Membrane Synovial membrane Capsule that encloses a joint Manufactures and contains synovial fluid 1.02 Remember the structures of the skeletal system 53 1.02 Remember the structures of the skeletal system Essential Standards: • What is the process of bone formation? • What are the structures of the long bones? • What are the structures of the skeletal system? 1.02 Remember the structures of the skeletal system 54 1.02 Remember the structures of the skeletal system The End 1.02 Remember the structures of the skeletal system 55
