Introduction


Refer back to your skeletal diagram where you
named the bones of the body that you know.
As we progress through today’s lesson and label
the bones, if the bone is one that you labeled
correctly on your diagram, place a check mark
next to the bone.
Anatomy-Skeletal System
Objectives

Students will be able to:
 Define anatomical terms.
 Identify the bones of the upper extremity of
the appendicular skeleton.
 Label the bones.
