Agenda:
Bone labeling—
On your own
As a table
Lecture/Notes
Video support

2. 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)

3. 52
Background Knowledge: Bones I know!!!
Video notes
15 bullets

4. 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

5. 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)

6. 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

8. 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

9. 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)

10. 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)
