Physiology (from Greek f?s??, physis, "nature, origin"; and -????a, -logia, "study of") is the study of the mechanical, physical, and biochemical functions of living organisms. Physiology has traditionally been divided between plant physiology and animal and all living things physiology but the principles of physiology are universal, no matter what particular organism is being studied. For example, what is learned about the physiology of yeast cells may also apply to human cells that one may be studying. The field of animal physiology extends the tools and methods of human physiology to non-human animal species. Plant physiology also borrows techniques from both fields. Its scope of subjects is at least as diverse as the tree of life itself. Due to this diversity of subjects, research in animal physiology tends to concentrate on understanding how physiological traits changed throughout the evolutionary history of animals. Other major branches of scientific study that have grown out of physiology research include biochemistry, biophysics, paleobiology, biomechanics, and pharmacology. Human physiology dates back to at least 420 B.C. and the time of Hippocrates,[1] the father of medicine. The critical thinking of Aristotle and his emphasis on the relationship between structure and function marked the beginning of physiology in Ancient Greece, while Claudius Galenus (c. 126-199 A.D.), known as Galen, was the first to use experiments to probe the function of the body. Galen was the founder of experimental physiology.[2] The ancient Indian books of Ayurveda, the Sushruta Samhita and Charaka Samhita, also had descriptions on human anatomy and physiology. The medical world moved on from Galvanism only with the appearance of Andreas Vesalius and William Harvey.[3] During the Middle Ages, the ancient Greek and Indian medical traditions were further developed by Muslim physicians, most notably Avicenna (980-1037), who introduced experimentation and quantification into the study of physiology in The Canon of Medicine. Many of the ancient physiological doctrines were eventually discredited by Ibn al-Nafis (1213-1288), who was the first physician to correctly describe the anatomy of the heart, the coronary circulation, the structure of the lungs, and the pulmonary circulation, for which he is considered the father of circulatory physiology.[4] He was also the first to describe the relationship between the lungs and the aeration of the blood, the cause of pulsation,[5] and an early concept of capillary circulation.[6]

2. Blue Heaven: Why the Sky Is Blue
November 06, 2009
The appearance of a strange colored marking on the skin at birth has always been a rather peculiar physiological occurrence, and for some a cause for alarm. Why do people have birthmarks? Is it a disfigurement? Is it a sign of some sort of disease? Could it even have some mystical property?
Although not mystical in the superstitious sense, the answers as to why do people have birthmarks remain mysterious nonetheless. What is known about them is that while they typically appear from birth, there are instances where they emerge after the baby has been born. Some birthmarks eventually disapp... (read more)

Erectile dysfunction (ED) can be caused by many physiological factors such as obesity, diabetes, hypertension, chronic illness and high cholesterol. If occurring for more than three months, it is recommended to seek help. "There can be emotional connections, as well," Pyatt says. "Stress can lead to hormonal imbalances, which can contribute to ED. ED is also a side-effect of certain medications. Low sex drive in patients taking anti-depressant medication is very common as well." Even lack of a good night's sleep can affect performance.

7. Chiropractic Healing And The System Of Healthcare
November 06, 2009
Osteopathy is a system of healthcare based on the belief that disease is the direct result of the relationship between physiological function and anatomical structure. In osteopathy, function and structure are interdependent. A healthy musculoskeletal system plays a pivotal role in recovery and disease prevention. 'Structure governs function' - this is the tenet of osteopathy. By structure, this means muscles, ligaments, bones, organs and fascia.
The credit for initiating this system of healing is given to Andrew Taylor Still, who started this treatment at the end of the American Civil Wa... (read more)

10. Pigs to help us with diabetes**
October 29, 2009
Given the current practical limitations of glucose monitoring and insulin delivery systems, in addition to the current shortage of cadaveric organs, an alternative source of cells that can sense blood glucose levels and respond by releasing appropriate amounts of mature insulin must be identified to turn the promise of cellular therapy for diabetes into a reality for all those who would benefit. Xenogeneic cells are a potential source of cells for transplantation therapy. Because pigs regulate glucose in a similar physiological range to that of humans, and because porcine insulin has been...

11. Where Are You In Abraham Maslow's Hierarchy Of Needs?
October 29, 2009
As a social work and psychology student, Abraham Maslow's hierarchy of needs was a theory in which we focused a great deal of time. According to Maslow, there are five levels of needs, ranging from physiological to self-actualization. It is difficult to move from one level to the next without first meeting your needs at the lower level. If you can identify where you are currently at in the hierarchy, it will give you a better understanding of where you are coming from and what you need to do to reach the fifth and final step, self-actualization. The first level, at the base of the pyramid... (read more)

15. Avoid Workout Injuries
October 26, 2009
From some trainers 'No pain, no gain' really means 'you should feel some pain'. While mild discomfort is to be expected, especially for those just beginning a new fitness routine, pain is a natural warning sign. Pay attention to it.
A good workout routine will test you, but shouldn't damage you. As muscles get used, especially somewhat beyond their usual range, lactic acid, micro-tears and other physiological changes occur that result in muscles being built up stronger than before.
But if you are experiencing back pain, neck aches, knee joint soreness and other symptoms, you should c... (read more)

16. Is Singing a Natural or Crafted Talent?
October 23, 2009
It's a rather old question. Are great vocal pipes something you're born with or something you build from the ground up? Consider the fact that speaking and singing are not the major function of your vocal folds. Their physiological function is to support breathing and protect your air passages (surprising considering how much we use the voice). Some people just have a natural advantage in sports, modeling, or other activities because of physical characteristics they're born with. The same is true of the voice. There are plenty of people walking the streets who have no interest o... (read more)

Different phases of lovemaking (Excitement, Plateau, Orgasm and Resolution) play different role in the whole act of lovemaking. In this article, we will discuss in brief about the fourth phase i.e. the resolution phase.
