Study Notes
Anatomy and Physiology Overview
- Anatomy: The study of body structures, including names, locations, and compositions; derives from Greek meaning “to cut open.”
- Physiology: The study of body functions and processes; emphasizes how structures work together.
- Two major branches of anatomy:
- Gross Anatomy: Study of large structures visible without a microscope.
- Microscopic Anatomy: Study of structures at the cellular and tissue level.
Divisions of Gross Anatomy
- Surface Anatomy: Examines external features and markings.
- Regional Anatomy: Focuses on specific areas, such as the head or limbs; utilized in medical education.
- Systemic Anatomy: Studies organ systems working together; primary focus in this course.
- Developmental Anatomy: Looks at structural changes from fertilization to maturity, with embryology as its subset.
- Clinical Anatomy: Involves medical specialties and anatomical changes during illness.
Divisions of Microscopic Anatomy
- Cytology: Focus on individual cells and their components.
- Histology: Studies the structure and organization of tissues.
Specialties of Physiology
- Cell Physiology: Examines chemical and molecular processes within cells.
- Special Physiology: Investigates specific organ functions.
- Systemic Physiology: Looks at how organ systems cooperate.
- Pathological Physiology: Studies how diseases affect organs and systems.
Levels of Organization
- Atoms: Smallest units of matter.
- Molecules: Combinations of atoms; active chemicals.
- Organelles: Specialized structures within cells.
- Cells: Basic living units of all organisms.
- Tissues: Groups of similar cells performing specific functions.
- Organs: Combinations of multiple tissue types for specific tasks.
- Organ Systems: Groups of organs working together.
- Organism: A complete individual, including all previously mentioned levels.
Homeostasis
- Defined as the maintenance of a stable internal environment, critical for normal physiological functions.
- Homeostasis involves feedback loops:
- Negative Feedback: Mechanism opposes initial stimulus (e.g., temperature regulation).
- Positive Feedback: Mechanism enhances initial stimulus (e.g., blood clotting, childbirth).
Anatomical Terms and Reference Frames
- Standard Anatomical Position: Body standing upright, facing forward, arms at sides with palms forward.
-
Anatomical Directions:
- Proximal/Distal, Medial/Lateral, Anterior/Posterior, Cranial/Caudal.
-
Planes of Section:
- Sagittal Plane: Divides body into left and right.
- Frontal Plane (Coronal): Divides body into anterior and posterior.
- Transverse Plane: Divides body into superior and inferior.
Body Cavities
- Body Cavities: Internal compartments that protect and compartmentalize organs.
- Serous Membranes: Line body cavities and cover organs, consisting of visceral and parietal layers, reducing friction through a lubricating fluid.
Major Body Cavities
-
Ventral Body Cavity: Divided by the diaphragm into:
- Thoracic Cavity: Houses pleural (lungs) and pericardial (heart) cavities, lined by respective serous membranes.
- Abdominopelvic Cavity: Further divided into peritoneal, abdominal (liver, stomach), and pelvic (bladder, reproductive organs) cavities, with specific serous membranes.
