Visual Analysis Essay

            The image that I chose is a diagram of a strand of muscle, which is intended for anyone in the medical field or anyone who intends to be. It shows the viewer just what a major muscle group is composed of, what each individual part looks like as well as labeling all the parts to educate the viewer on such things. I found this image on a website called medicallook.com which is dedicated to breaking down the human anatomy and its various ailments into easier information to understand. Medicallook.com is updated often and has been updated already in 2014, keeping the information up to date and current.
            In the diagram, all the major parts are displayed and labeled. The image includes a bone, a tendon and the actual muscle, which is sliced in half to show the various fibers, blood vessels and bundles with their respective connective tissues within the muscle. An easier way to think of this is by thinking about a long strand of muscle, a bicep for example. Within that single strand, there are multiple more strands called muscle bundles, which are wrapped in connective tissue. Within these bundles are more strands, which are called muscle fibers, each of which are also wrapped in their own connective tissue.
            As a physical therapist, clearly I have to know a lot about the human anatomy. My job will always revolve around know the in depth knowledge and manipulation of the human body. Muscle and tendon issues are arguably the most common problems that physical therapists have to treat. Because of this, diagrams such as the one from this site become incredibly useful in understanding the client’s infirmities. For example, a muscle strain or sprain is the over extension or tearing of the either the tendon or the muscle fibers, both of which are displayed in the diagram.
            I feel this picture as             a whole, represents the common core of all physical therapists, and any medical professional for that matter. Within this relatively simple picture, you can derive so much information. You can tell what a proper muscle should look like, the function of each piece of the muscle, certain issues that could result with the muscle and so much more, as long as you know what to look for. This is very similar to any medical profession, especially physical therapy. As a physical therapist, you’re not always given a clear idea of what exactly is wrong with your patient and furthermore, how to best treat them. For example, a patient may come in, complaining they have sharp pain in their lower back. Generally the person wont have any physical signs of the injury on the surface level and the physical therapist will then have to feel with his hands and take in situational information to properly diagnose the person. Thus, each physical therapist has to draw upon what they already know and look for the tiny details to decipher the true implications of the person’s ailment, much like how one must take in all the small details in the picture to know the total amount of information that it provides.
            So how do you find these tiny bits of information for the diagram? Well certain parts are easier than others. Clearly it shows how a normal muscle should look, fibers making bundles, which make the entire muscle. That doesn’t take a whole lot of thinking. But the functions and possible injuries take a little more work and a bit of background knowledge. The functions of the fibers and bundles are to contract and relax for muscle movement, made simple by the shape and positioning of each strand. The formation of these is also precise to strengthen and protect the muscle. This info can be derived based off of inference and prior knowledge on the subject matter, much like how a physical therapist performs their work (by inference and prior knowledge). Figuring our possible injuries is found the same way. If these fibers we to be severed or over extended, the muscle will not be able to contract and function as it is supposed to. Injuries such as these are what we know as sprains and strains.
            As a whole, I feel like this diagram of a muscle not only pertains to my future career field but also represents my future profession as a whole. A lot of information can be derived from this single image, which runs parallel to the techniques physical therapists must use to successfully do their jobs.
