An overview of anatomy and physiology

Gross Anatomy Gross anatomy can be further subdivided into three different fields: Surface anatomy or superficial anatomy is the study of external anatomical features without dissection.

There are two major types of anatomy. Other larger structures can readily be seen, manipulated, measured, and weighed. The organism level is the highest level of organization. A scientist wants to study how the body uses foods and fluids during a marathon run.

Many organs participate in more than one system such as the heart and kidney , and systems might be organized by function, by embryological origin, or by other categorizations. Key Terms anatomy: The study of the body structure of animals. This is a micrograph of nerve cells from the brain. For instance, the neuroendocrine system is the complex interactions of the neurological and endocrinological systems. Like most scientific disciplines, anatomy has areas of specialization. It is monitored by the brain and nervous system and regulated by the physiology and activity of individual organs. At a smaller level of analysis, the function of these nerves and muscles likewise relies on the interactions of specific molecules and ions. Sometimes called superficial anatomy.

At a smaller level of analysis, the function of these nerves and muscles likewise relies on the interactions of specific molecules and ions. Imagine, for example, trying to appreciate the unique arrangement of the bones of the human hand if you had no conception of the function of the hand.

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.

The traditional divisions by system are somewhat arbitrary. The brain also signals the heart to beat faster so other organs and tissues receive the oxygen they need.
