Some references suggest that the human body has more than 600 muscles and other references suggest that there are over 700 muscles in the human body. The naming of anatomical structures provide a lot of information as long as you understand the meaning of the terminology. Most of us understand the simple concept of a muscle can contract and relax. We can simply think about contracting our biceps muscle and it happens. But there are other processes within the body that occur without our consciousness, for example the human heart, is composed of cardiac muscle. The human heart contracts and relaxes without conscious control, in other words, the human heart is self exciting or functions involuntarily. Other examples of organs within our bodies that we cannot control consciousness are the digestive system, our breathing, or the arteries responsible for delivering oxygenated blood throughout our bodies.
Anatomy is filled with words that help us understand the shape, the size, the location, and even the function of a muscle. Muscle fibers run in different directions, straight, across, or diagonal. We can also say that those muscles run rectus, transverse, or oblique. If you want to say that a muscle is large, we can say “maximus” and if you want to say something as small, which is a “minor”. If we want to say that a muscle is circular, we can say “orbicularis” and if we want to say that a muscle resembles a saw-tooth pattern, we can use the word “serratus” to describe it.
