What are appendicular bones?
responsible for making movement, permitting locomotion and giving us the ability to grasp. and manipulate objects.

examples of appendicular bones
femur, fibular, ulna, scapula
what are the 5 types of bones plus an example.
short bones(, long bones(humerus,femur), sesamoid bones(patella), flat bones(scapular, ribs), irregular bones(vertebrae, illium).
