Final answer:
The subdivisions of anatomy include gross, regional, systemic, and surface anatomy, each focusing on different aspects and scales of the body's structures.
Step-by-step explanation:
Subdivisions of anatomy include gross, regional, systemic, and surface anatomy. These categories help in organizing the study of the body's structures. Gross anatomy, also known as macroscopic anatomy, is the study of the larger structures of the body that are visible without magnification. Microscopic anatomy, on the other hand, involves studying structures that can only be observed with a microscope, including cytology (study of cells) and histology (study of tissues). Regional anatomy considers the interrelationships of all structures within a specific body area, while systemic anatomy focuses on the structures that comprise individual body systems, such as the muscular or skeletal systems.
