Definition: Anatomy studies the structure of the human body, from cells to systems.
Methods of Study:
Inspection: Visual examination.
Palpation: Feeling body parts to assess characteristics.
Auscultation: Listening to body sounds for health evaluation.
Percussion: Tapping body surfaces for insights on structures.
Cadaver Dissection: Direct study of anatomy via preserved bodies.
Comparative Anatomy: Analyzing anatomical similarities/differences across species.
Imaging Techniques: Non-invasive methods like x-rays and MRIs for internal visualization.
Levels of Organization:
Organism: Entire living entity.
Organ Systems: Groups of organs (e.g., digestive system).
Organs: Distinct functional structures (e.g., heart).
Tissues: Similar cells performing a function.
Cells: Basic life units.
Organelles: Structures within cells (e.g., mitochondria).
Molecules and Atoms: Building blocks of matter.
Key Points:
Anatomical variants exist in approximately 30% of individuals.
Characteristics of Life: Organization, metabolism, and homeostasis.
Major Themes:
Cell Theory: All organisms consist of cells.
Evolution: Awareness of evolutionary adaptations in anatomy.
Structure and Function: The relationship between anatomy and function is crucial for understanding biology.
