Skeletal system

This tutorial by Megan from Ken Hub explores the human skeletal system, dividing it into the axial and appendicular skeletons. The axial skeleton includes the skull and trunk, while the appendicular skeleton covers the shoulder girdle, upper limbs, pelvic girdle, and lower limbs. Key bones and their features are discussed, along with clinical notes on bone diseases like osteosarcoma, chondrosarcoma, and rickets.
