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.
