Biology 201: Tissue & Skeletal System

1) Fill out the chart below with the correct bone classification (Word Bank A) and example (Word Bank B).

Word Bank A: Word Bank B:

Flat Sesamoid Femur Long Short Sternum Vertebrae Irregular Tarsals

Bone Classification Description Function Example

1) Long Greater length than width Support the weight of the 6) Femur body

2) Short Length and width are Provide stability & assist 7) Tarsals closer to the same in movement

3) Flat Thin, flat surface Protect internal organs 8) Sternum

4) Irregular Complex, elaborate Protect internal organs 9) Vertebrae structure that does not fit and provide attachment into the other categories points for muscles

5) Sesamoid Small imbedded Assist with weight 10) Patella into tendons bearing and pressure application
