Study Notes
Anatomy and Physiology Key Terms
- Orbit: Composed of the maxilla, zygoma, and frontal bone.
- Sinoatrial Node: Initiates the electrical impulse of the heart.
- Respiration vs. Ventilation: Respiration is gas exchange while ventilation is the movement of air.
- Dorsal Respiratory Group (DRG): Located in the brain stem; responsible for initiating inspiration.
Blood and Circulatory System
- Average Blood Volume: Approximately 6 liters in an adult.
- Deoxygenated Blood Return: Inferior vena cava returns blood from the abdomen, pelvis, and lower extremities to the right atrium.
- Perfusion: Adequate circulation of blood within an organ to meet current cellular needs.
Skeletal and Muscular System
- Axial Skeleton: Includes skull, face, thorax, and vertebral column.
- Hinge Joint: The elbow is classified as a hinge joint.
- Phalanges: Bones that make up the fingers and toes.
Nervous System
- Autonomic Nervous System: Controls heart function.
- Connecting Nerve Function: Connects sensory and motor nerves, bypassing the brain.
- Reticular Activating System: Governs wakefulness.
Respiratory System
- Hypoxic Drive: Backup respiratory control system responding to low blood oxygen levels.
- Epiglottis: Leaf-shaped tissue preventing food from entering the trachea during swallowing.
- Seesaw Respirations: Respiratory distress sign typically seen in infants and children.
Digestive System
- Small Intestine: Primary organ for the absorption of digestion products.
- Gallbladder: Concentrates and stores bile produced by the liver.
Cardiac Cycle
- Diastole: Phase when ventricles fill with blood.
- Medulla Oblongata: Monitors pH changes and regulates diaphragm contraction.
Injuries and Conditions
- Distal Humerus Fracture: Describes a fracture near the elbow.
- Calcium Deficiency: Leads to brittle bones.
Anatomical Directions
- Inferior: Refers to body parts closer to the feet.
- Proximal: The elbow is proximal to the wrist.
- Abduction: Movement away from the body's midline.
Additional Notes
- Bilateral Chest Movement: Indicator of adequate adult breathing.
- Agonal Respirations: Ineffective breaths needing assistance, typically occurring before cardiac arrest.
- Plantar Aspect: Refers to the bottom of the feet, relevant for injuries from jumping.
- Average Air Composition: Inhaled air contains 21% oxygen; exhaled air contains 16% oxygen.
