Study Notes
Ventral Body Cavity
- Divided into thoracic and abdominopelvic cavities by the diaphragm.
- Each thoracic cavity contains a lung, surrounded by pleural cavities.
- Mediastinum houses the trachea, esophagus, thymus, and major vessels.
Thoracic Cavity
- Comprises right and left pleural cavities surrounding respective lungs.
- Contains the pericardial cavity which surrounds the heart.
Abdominopelvic Cavity
- Divided into abdominal and pelvic cavities.
- Abdominal cavity contains digestive organs and glands.
- Pelvic cavity houses the urinary bladder, reproductive organs, and the last portion of the digestive tract.
Protection and Structure
- Ventral body cavity protects internal organs and allows for organ movement.
- Linings prevent friction between organ movements.
Serous Membranes
- Thin, strong membranes lining cavities not open to the outside.
- Produce fluid transudate to reduce friction.
- Comprised of a parietal layer (covers cavity) and a visceral layer (covers organs).
Specific Serous Membranes
- Pleura: Lines and covers lungs within pleural cavities.
- Peritoneum: Lines the abdominal cavity and covers abdominal organs.
- Pericardium: Lines the pericardial cavity and covers the heart.
Retroperitoneal Space
- Area behind peritoneum, in front of the muscular body wall.
- Contains pancreas, kidneys, ureters, adrenal glands, and parts of the digestive tract.
Cutaneous and Synovial Membranes
- Cutaneous Membrane: Skin; thick, waterproof, and dry.
- Synovial Membranes: Line moving joints, produce synovial fluid for lubrication.
Anatomical Terminology
- Unilateral/Ipsilateral: Pertaining to one side.
- Bilateral: Pertaining to both sides.
- Contralateral: On opposite sides.
Position and Directional Terms
- Flexion/Extension: Bending/straightening joints.
- Abduction/Adduction: Movement away/toward the midline.
- Pronation/Supination: Turning arm/foot downward/upward.
Terms of Movement
- Retraction/Protraction: Movement backward/forward.
- Elevation/Depression: Raising/lowering parts.
- Rotation/Circumduction: Turning around an axis/circular motion.
Body Regions
- Divided into four quadrants: Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), and Left Lower Quadrant (LLQ).
Characteristics of the Human Body
- Organization increases complexity in structure and function.
- Metabolism includes all chemical reactions in the body.
Body Systems Overview
- Each system serves distinct functions and consists of major organs:
Cardiovascular System
- Composed of the heart, blood, and blood vessels.
- Distributes materials and assists in temperature control.
Lymphatic System
- Includes spleen, thymus, lymphatic vessels, lymph nodes, and tonsils.
- Defends against infection and returns tissue fluids to the bloodstream.
Respiratory System
- Major organs include nasal cavities, lungs, and trachea.
- Facilitates gas exchange and sound production.
Digestive System
- Comprises organs like the stomach, intestines, and liver.
- Processes food, absorbs nutrients, and stores energy.
Urinary System
- Consists of kidneys, ureters, urinary bladder, and urethra.
- Excretes waste, regulates water balance, and stores urine.
