Anatomy is the branch of science that studies the structure of living organisms. It examines how bodies are built, from the smallest cells to complete organ systems. Through methods like dissection and imaging, anatomy reveals the intricate design of life itself.
Anatomy is divided into several specialized branches. Gross anatomy studies structures visible to the naked eye, like organs and bones. Microscopic anatomy examines tiny structures using magnification, including cells and tissues. Developmental anatomy tracks how structures change and grow over time, from embryo to adult.
The human body consists of interconnected systems working together. The skeletal system provides structure, while muscles enable movement. The circulatory system transports blood throughout the body. The nervous system controls and coordinates functions. The respiratory system manages breathing, and the digestive system processes food for energy.
Anatomy employs various study methods. Dissection involves the careful examination of cadavers to understand internal structures. Medical imaging like X-rays and MRI scans allow non-invasive study of living subjects. Microscopy reveals cellular details invisible to the naked eye. Modern 3D modeling creates detailed digital reconstructions for educational and research purposes.
