Study Notes
Cardiovascular II: Conduction, Histology, and Development
- Course Learning Objectives (Cardiovascular): Recall the networks allowing gas and nutrient exchange throughout the body. Trace blood flow and identify related structures in the cardiovascular system.
Lecture Learning Objectives
- 1. Trace the heart's conducting system, identifying the impulse-traveling structures
- 2. Identify and describe the cardiac cycle events, focusing on diastole, systole, lub, and dub
- 3. Recall the anatomical location for auscultating each heart chamber
- 4. Describe the autonomic innervation of the heart (its origins and structures)
- 5. Describe how referred pain from the heart affects dermatomes in the upper limb
- 6. Visually identify histological structures and layers in cardiac muscle
- 7. Describe major heart development events (heart tube formation, cardiac layers/walls/folding, heart partitioning, valve development)
- 8. Trace primordial heart circulation
Heart Conduction
- 1. Review associated heart structures
- 2. Learn nervous conduction-associated structures, and their excitation order
- 3. Integrate the above information
