Anatomy and Physiology
Some specializations within each of these sciences follow:. Each perspective provides information about how or why a living system functions:. In many cases, stable conditions are maintained by negative feedback. Conditions are constantly monitored by receptors and evaluated by the control center.
When the control center determines that conditions have returned to normal, corrective action is discontinued. Thus, in negative feedback, the variant condition is canceled, or negated, so that conditions are returned to normal.
The regulation of glucose concentration in the blood illustrates how homeostasis is maintained by negative feedback. After a meal, the absorption of glucose a sugar from the digestive tract increases the amount of glucose in the blood. In response, specialized cells in the pancreas alpha cells secrete the hormone insulin, which circulates through the blood and stimulates liver and muscle cells to absorb the glucose. Once blood glucose levels return to normal, insulin secretion stops.
Later, perhaps after heavy exercise, blood glucose levels may drop because muscle cells absorb glucose from the blood and use it as a source of energy for muscle contraction. In response to falling blood glucose levels, another group of specialized pancreatic cells beta cells secretes a second hormone, glucagon. Glucagon stimulates the liver to release its stored glucose into the blood. When blood glucose levels return to normal, glucagon secretion stops. Such positive feedback is uncommon but does occur during blood clotting, childbirth labor contractions , lactation where milk production increases in response to an increase in nursing , and sexual orgasm.
In order to accurately identify areas of the body, clearly defined anatomical terms are used. These terms refer to the body in the anatomical position—standing erect, facing forward, arms down at the side, with the palms turned forward. In this position, the following apply:.

Anatomy describes the structure and location of the different components of an organism to provide a framework for understanding. Human anatomy studies the way that every part of a human, from molecules to bones, interacts to form a functional whole. There are two major types of anatomy. Gross macroscopic anatomy is the study of anatomical structures that can be seen by the naked eye, such as the external and internal bodily organs. Microscopic anatomy is the study of tiny anatomical structures such as tissues and cells.

It is an old science, having its beginnings in prehistoric times. Anatomy and physiology , which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines , and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic and microscopic. Macroscopic anatomy, or gross anatomy , is the examination of an animal's body parts using unaided eyesight.
