Overview of Anatomy and Physiology
Anatomy and physiology are two interconnected fields of study that serve as the foundation for many health-related disciplines. While anatomy focuses on the structure of the body and its parts, physiology examines how those parts function and interact.
Definition and Scope
1. Anatomy:
- Study of the structure and organization of the body.
- Divided into several subfields:
- Gross Anatomy: Examination of structures visible to the naked eye.
- Microscopic Anatomy: Study of structures at the cellular and tissue levels.
- Developmental Anatomy: Focus on the changes in structure from conception through adulthood.
2. Physiology:
- Study of the functions of the body and its systems.
- Encompasses various systems, including:
- Cell Physiology: Functioning of cells and cellular processes.
- Systemic Physiology: Function of specific organ systems (e.g., cardiovascular, respiratory).
- Pathophysiology: Study of how disease affects normal physiological processes.
