Grays Anatomy for Students 2nd Edition.pdf

What is anatomy?
Anatomy includes those structures that can be seen grossly (without the
aid of magnification) and microscopically (with the aid of magnification).
Typically, when used by itself, the term anatomy tends to mean gross or
macroscopic anatomy-that is, the study of structures that can be seen
without using a microscopic. Microscopic anatomy, also called histology, is
the study of cells and tissues using a microscope.
Anatomy forms the basis for the practice of medicine. Anatomy leads the
physician toward an understanding of a patient's disease, whether he or
she is carrying out a physical examination or using the most advanced
imaging techniques. Anatomy is also important for dentists, chiropractors,
physical therapists, and all others involved in any aspect of patient
treatment that begins with an analysis of clinical signs. The ability to
interpret a clinical observation correctly is therefore the endpoint of a
sound anatomical understanding.
Observation and visualization are the primary techniques a student should
use to learn anatomy. Anatomy is much more than just memorization of
lists of names. Although the language of anatomy is important, the network
of information needed to visualize the position of physical structures in a
patient goes far beyond simple memorization. Knowing the names of the
various branches of the external carotid artery is not the same as being
able to visualize the course of the lingual artery from its origin in the neck
to its termination in the tongue. Similarly, understanding the organization of
the soft palate, how it is related to the oral and nasal cavities, and how it
moves during swallowing is very different from being able to recite the
names of its individual muscles and nerves. An understanding of anatomy
requires an understanding of the context in which the terminology can be
remembered.
