7.2 Skeletal Organization Sponge: Set up Cornell Notes on pg. 53 Topic: 7.2 Skeletal Organization Essential Question: What is the MAJOR difference between the axial and appendicular skeleton? TEXT: 205-208 7.2 Skeletal Organization 2.1 Atoms, Ions, and Molecules What is the MAJOR difference between the axial and appendicular skeleton? Get Textbook Agenda: Bone labeling— On your own As a table Lecture/Notes Video support

Objective SWU: that the human skeleton is organized into axial and appendicular sections As tables, SW: use their background knowledge to label the major bones of the body (no books/internet)

52 Background Knowledge: Bones I know!!! Video notes 15 bullets

BY YOURSELF: list ANY bones in the human body that you know Top ½ of Pg. 52 BY YOURSELF: list ANY bones in the human body that you know

PRACTICE!!!!!!!!!!!! Send someone up for the human skeleton labeling sheet Using your own prior knowledge and the key at the bottom of the pg., please label as many bones in the body that you can (in PENCIL)

Pg. 209-239 Now correct your paper IN PEN Circle the bones you got RIGHT Cross-off wrong answers Please make sure to write CORRECT ANSWERS

TAPE P. 52 Frontal bone Skull Clavicle Mandible Scapula Humerus Sternum Costal Cartilage Ribs Radius Vertebra Carpals Ilium Ischium Ulna Metacarpals Coccyx Phalanges Femur Patella Calcaneus Fibula Tibia Tarsals Metatarsals Phalanges

P. 53 Skeletal Organization Usually 206 bones in the body Actual number varies from person to person/age Babies are born with about 270 bones that will fuse over the first few years of their life

Axial Skeleton: consists of boney and cartilaginous parts that support and protect the organs of the head, neck and trunk. Includes: Skull Hyoid bone (supports the tongue) Vertebral column Vertebrae (spine) Sacrum (Lower spine) Coccyx (tailbone) Thoracic cage (rib cage) Ribs Sternum (breast bone)

Appendicular Skeleton: Anchors the limbs to the axial skeleton- enables movement Pectoral girdle Scapula (Shoulder blade) Clavicle (collarbone) Upper limbs Humerus ( upper arm bone) Radius (forearm-thumb) Ulna (forearm- pinky) Carpals (wrist) Metacarpals (hand) Phalanges (fingers) Pelvic girdle Coxae (cox-ee) (hip bones) pelvis Lower limbs Femur (thigh) Tibia (shin) Fibula (side-leg bone) Patella (knee) Tarsals (ankle) Metatarsals (foot) Phalanges (toes)
