Study Notes
Key Concepts of Anatomy and Physiology
- Anatomy: Study of the body's structure, including how organs are organized and their physical characteristics.
- Physiology: Study of the functions of the body's parts and systems, explaining how they work together, such as the heart's role in blood circulation.
- Pathophysiology: Focuses on the effects of diseases on normal bodily functions, including conditions like heart attacks and their consequences on organ performance.
Levels of Organization
- The human body is organized into several levels: cells, tissues, organs, organ systems, and the entire organism.
Major Organ Systems
- There are 12 essential organ systems that perform critical functions necessary for the body’s survival.
Homeostasis
- Definition: The body's ability to maintain a stable internal environment despite external changes, critical for survival.
Anatomical Position and Terminology
- Anatomical Position: A standardized posture used as a reference, where the body stands upright, arms at the sides, and palms facing forward.
- Relative Positions: Terms like superior, inferior, anterior, and posterior help describe the location of body parts relative to each other.
Body Planes
- Three major body planes are used to describe sections of the body:
- Transverse Plane: Divides the body into upper and lower parts.
- Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back) sections.
- Sagittal Plane: Divides the body into right and left sections.
Body Cavities
- The body contains major cavities that house vital organs:
- Cranial Cavity: Encloses the brain.
- Spinal (Vertebral) Cavity: Contains the spinal cord.
- Thoracic Cavity: Houses the heart and lungs.
- Abdominopelvic Cavity: Contains digestive organs and structures of the pelvis.
- Mediastinum: The area between the lungs, containing the heart and other structures.
- Pleural Cavities: Surround each lung.
- Pericardial Cavity: Encloses the heart.
Anatomical Terms for Body Regions
- The body can be described using anatomical terms for various quadrants and regions relevant for identification in medical contexts.
