Study Notes
Anatomy and Physiology
- Anatomy and physiology are complementary sciences that help in understanding the human body.
- Anatomy focuses on the structure of body parts and their interrelations, making it a concrete field of study.
- Features of anatomy can be directly observed or examined, increasing its appeal.
- Physiology addresses the function of body systems and the processes that sustain life.
- The functioning of body parts can only be fully understood through their anatomical structure.
Reference Values
- Healthy reference values for studies typically use a 155 lb (70 kg) young male and a 125 lb (57 kg) young female.
- Despite anatomical variations among individuals, over 90% of structures align with textbook descriptions.
- Extreme anatomical variations are rare due to their incompatibility with life.
Subdivisions of Anatomy
- Anatomy encompasses various subdivisions, each worthy of in-depth study.
- Gross (macroscopic) anatomy covers large structures visible without magnification, like the heart and lungs.
- Microscopic anatomy studies structures that require magnification to be seen, such as tissues and cells.
- Microscopic anatomy further divides into:
- Cytology: the study of individual cells.
- Histology: the examination of tissue structures.
