3. Introduction
• Anatomy – science deals with structure of body, from macroscopic to
microscopic level
• Anatome = (Greek anatomē, 'dissection') is the branch of biology
concerned with the study of the structure of organisms and their
parts
• Anatomical Nomenclature = to eliminate unambiguous description of
thousands of structures is impossible without an extensive and often
highly specialized vocabulary.

2. Systemic anatomy
3. Clinical (applied anatomy)
