Study Notes
Cardiovascular System 1 - Week 2
- Session Focus: Thorax, heart structure, blood flow, and major vessels.
- Specific Learning Outcomes: Students should identify thoracic and abdominal organs, tissue layers, major viscera, relationships between organs and body parts, heart chambers, and blood flow through the heart.
- Thoracic and Abdominal Organs: Students should identify the underlying anatomy of major organs, utilizing surface lines.
- Body Tissues: Students will identify and determine layers and viscera (thoracic, abdominal, pelvic cavities).
- Anatomical Relationships: Students should describe the relationships between organs using appropriate terminology.
- Heart Anatomy: Students should identify heart chambers (including anterior, posterior, and base surfaces) and explain normal blood flow.
- Branches of the Aorta: Students will need to identify the arch of the aorta's branches (brachiocephalic artery, left common carotid artery, and left subclavian artery), understand their supply regions, identify the descending thoracic aorta's branches (intercostals, bronchial, esophageal, mediastinal), and describe their relations.
- Azygos System: Students will describe the azygos, hemiazygos, and accessory hemiazygos veins, their communications with the caval system, and azygos functions.
- Variations and Clinical Significance: Students should be aware of possible variations in the arch of the aorta's branches and their clinical significance.
- Innervation: Students should know the relationship of the ligamentum arteriosum to the left vagus nerve and innervation of the mediastinum, locate the esophageal, pulmonary, and deep cardiac plexuses.
- Vascular Anatomy (in Cadavers): Students will need to locate major vascular anatomy in cadaver specimens.
- Suggested Readings: Moore et al., 2011 (Essential Clinical Anatomy), Netter, 2003 (Atlas of Human Anatomy) are suggested for detailed anatomical reference material.
Station 1: Thoracic Vasculature and Innervation
- Blood Vessels Identified: Superior vena cava, Inferior vena cava, Pulmonary trunk, Right and left pulmonary veins, Ascending aorta.
- Aortic Sinuses: Identify posterior, anterior, and non-coronary sinuses, their relationship to coronary arteries (left and right).
- Arch of the Aorta Branches: Identify brachiocephalic artery, left common carotid artery, left subclavian artery, and their respective regions of supply.
- Descending Thoracic Aorta Branches: Identify bronchial, esophageal, pericardial, mediastinal, posterior intercostals, subcostal, and superior phrenic arteries (note some are too small to be easily seen on all specimens).
- Azygos System Structures: Identify azygos, hemiazygos, and accessory hemiazygos veins.
Station 2: Structure of the Heart
- Pericardial Cavity: Understand the transverse and oblique pericardial sinuses, their clinical and surgical significance including coronary artery bypass grafting.
- Heart Position and Surfaces: Identify and note the position of the heart in the thorax, and its relationships to surrounding structures. Identify the heart's surfaces (apex, base, anterior, posterior).
- Potential Abnormalities: Understand positional abnormalities like dextrocardia and mirror-image positioning.
Station 3: Vascular Anatomy (Head & Neck/ Upper Limb)
- Head and Neck: Identify sternocleidomastoid muscle, thyroid cartilage (Adam's apple), common carotid artery, internal and external carotid arteries.
- Upper Limb: Identify brachiocephalic trunk, subclavian artery, axillary artery, and brachial artery. Note and locate them in position.
- Vascular Drainage/Patterns: Understand superficial and deep venous drainage of the hand, venae comitantes.
- Pulse Points: Radial artery as a common pulse point for blood pressure measurements is highlighted, noting its location and importance for clinical assessment.
- Arteries of the Hand and Wrist: Identify superficial palmar, deep palmar, dorsal networks of vessels, and common palmar digital arteries.
Station 3 (cont.) - Abdomen and Pelvis
- Aorta and its Branches: Locate the aorta and understand its branching into common iliac arteries, then internal and external iliac arteries, and further branches in the lower limb.
- Variations (AAA): Note the possibility of abdominal aortic aneurysms (AAA).
- Lower Limbs: Learn to locate and understand how the external iliac artery becomes the femoral, popliteal, anterior/posterior tibial arteries.
- Surface Landmarks: Recognize and identify important landmarks like inguinal ligament and mid-inguinal points.
- Veins: Note the location of major veins throughout the lower extremity, including the great saphenous and short saphenous veins.
Self-Directed Learning Station
- Students should learn to compare the tissues of various body locations.
- Use visuals (histology slides, anatomic specimens) for deeper understanding.
