Anatomy is the study of structures’ location and function. Physiology is the study of how these macro and micro structures work to maintain homeostasis in the organism. It includes cellular, tissue, organ, and system functions. Anatomy and physiology (A&P) are vital to understand in occupational therapy (OT) when working with patients. Typically, OT patients require rehabilitation as they have lost the ability to do anything from daily activities to difficult job demanding tasks. To understand the needs of these patients, it is first important to know how the relevant A&P is affected. For example, if a patient is being seen for wrist pain while typing on a computer, the therapist will need to have a thorough understanding of all the muscles, ligaments, and bones involved in moving the forearm, wrist, and digits. They will also need to understand the physiology behind muscle contraction, development of new tissues, nerve pain, and blood circulation.
Before we attempt to assess the effect of work on the health of man, it is expedient to summarize briefly our knowledge of the human body and the working of its organs. Of Course, all the organs of the body take part in the life, and hence in the work, of human. However, certain parts of the body that determine working capacity are more particularly involved; they can therefore be considered as representative, and only they need to be studied.
At the end of this course, the student will be able to:
- Discuss the functionality of human physiology
- Identify the occupational physiology related problems
