Introduction
What is Anatomy?
• Study of the STRUCTURE of the Human
Body

• Physiology is the study of the FUNCTION
of the human body
Divisions of Anatomy
• Gross Anatomy
• Structures that can be

of the body
• Frontal section – divides the body into
front and back sides
• Transverse (cross) section – cut straight
across the body
