Document Summary
Human physiology - the scientific study of the functions of our body. Teleogical approach - explains the body functions in terms of meeting a bodily need, without considering how this outcome is accomplished, it emphasizes the why or purpose of body processes. Mechanistic approach view the body as a machine whose mechanisms of action can be explained in terms of cause-and-effect sequences of physical and chemical processes, the same types of processes that occur in other components of the universe. Physiologists explain the how of events that occur in the body. Teleogical response: to help warm you up, because shivering generates heat. Mechanistic response: shivering is that when temperature-sensitive nerve cells detect a fall in body temperature, they signal the temperature-sensitive area of the brain. In response, the brain activates nerve pathways that ultimately bring about involuntary, oscillating contraction-relaxation of skeletal muscle (shivering). Anatomy - the study of the structure of the body.
