Study Notes
Anatomy and Physiology Overview
- Anatomy examines body structures, derived from the term meaning "to dissect."
- Physiology focuses on the processes and functions of the body, with human physiology specifically studying the human organism.
Importance of Anatomy and Physiology
- Critical for understanding body responses to stimuli, environmental changes, diseases, and injuries.
Types of Anatomy
- Systemic Anatomy: Focuses on organ systems of the body.
- Regional Anatomy: Investigates specific body regions, often utilized in medical education.
- Surface Anatomy: Examines external features such as bone projections.
- Anatomical Imaging: Utilizes technologies like X-rays, ultrasounds, and MRI for visualization.
Structural and Functional Organization
-
Six Organizational Levels:
- Chemical Level: Smallest unit; includes atoms and molecules.
- Cellular Level: Comprises cells, the basic units of life, containing organelles like mitochondria and the nucleus.
-
Tissues: Collection of similar cells; four main types include:
- Epithelial
- Connective
- Muscular
- Nervous
- Organs: Composed of two or more tissue types working together; examples include the stomach, heart, and kidneys.
- Organ Systems: Groups of organs functioning together, such as the digestive and reproductive systems.
- Organism: Represents the complete entity with all organ systems collaborating, including microorganisms like intestinal bacteria.
