Anatomy

Excerpt from a lecture:

Hello and welcome to today’s anatomy lecture. Whereas in the previous lesson of our course we focused on the central nervous system, the cardiovascular system and the digestive system, their co-dependence and the major organs that perform important bodily functions, today we will discuss the skeletal system and the muscular system.

The skeletal system is a system of bones, which serve many vital roles, such as support, movement and calcium storage. An adult human being’s skeleton, which is the everyday term for the skeletal system, consists of 206 bones. Interestingly, infants are born with many more bones, between 300 and 350, which merge as the body develops.

Let’s now look at the main bones and the roles they play. At the top of our body, in the head, there is cranium, which is the bone structure protecting the brain. Below it there’s the mandible, which is the bone of the lower jaw. It moves vertically when we eat or speak.
