Gross anatomy is the study of the larger structures of the body, those visible without the aid of magnification (Figure 1a).Macro- means “large,” thus, gross anatomy is also referred to as macroscopic anatomy.Whereas anatomy is about structure, physiology is about function.

Other larger structures can readily be seen, manipulated, measured, and weighed.
The word “anatomy” comes from a Greek root that means “to cut apart.” Human anatomy was first studied by observing the exterior of the body and observing the wounds of soldiers and other injuries.
Dissection is still used in medical schools, anatomy courses, and in pathology labs.
In order to observe structures in living people, however, a number of imaging techniques have been developed.
Human anatomy is the scientific study of the body’s structures.
Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope.In contrast, systemic anatomy is the study of the structures that make up a discrete body system—that is, a group of structures that work together to perform a unique body function.For example, a systemic anatomical study of the muscular system would consider all of the skeletal muscles of the body.At a smaller level of analysis, the function of these nerves and muscles likewise relies on the interactions of specific molecules and ions.Even the three-dimensional structure of certain molecules is essential to their function.Physiologists may work from the organ level (exploring, for example, what different parts of the brain do) to the molecular level (such as exploring how an electrochemical signal travels along nerves).Form is closely related to function in all living things.Much of the study of physiology centers on the body’s tendency toward homeostasis.Homeostasis is the state of steady internal conditions maintained by living things.Later, physicians were allowed to dissect bodies of the dead to augment their knowledge.When a body is dissected, its structures are cut apart in order to observe their physical attributes and their relationships to one another.
