The skeletal system is the internal framework of the human body. This course will first discuss the types of bones that make up the skeleton. You will study its functions and learn that it provides support and protection, is involved in the production of blood cells, and enables motion and locomotion. You will then study the main types of tissues and tissue processes found in skeletal elements. You will also look into the structure of a typical long bone, flat bone, the bones of the cranium, and the sesamoid bones.

Joints can be classified according to the type of material holding the bones together, the relative mobility of the joint, and the degrees of freedom of the joint. This course will explain how joints can be ball and socket, hinge, or specialized. It will also cover the axial skeleton (which is the central supporting framework of the body) and the appendicular skeleton (which consists of the bones of the upper and lower members). You will also study the skull, rib cage, and the vertebral column.

The adult human skeleton is composed of 206 bones that provide the human body with a multifunctional structure and is connected by joints, cartilage, tendons, and ligaments. Upon the completion of this course, you will have gained a much better understanding of the human skeletal system, including the axial skeleton and the appendicular skeleton. So, check out the course today and learn how bones develop from the fetal through to the adult stages of life and the vital role it plays in maintaining human health!
