Physiology is the study of how living organisms function. Thus, human physiology deals specifically with the physiological attributes of the human body at various levels of organization, i.e. from cellular to tissue and ultimately, physiology at the biological system level. Human physiology is important because it imparts an in-depth understanding of the vital processes that..
Human Neurology deals essentially with the nervous system of humans. It also features the various theories put forward by prominent neurologists, such as Sigmund Freud and Carl Jung, and their analogies of the human brain and its inner workings. Objectives To impart information on the nervous system, particularly its cellular and physiological features To be..
