- anterior interventricular artery
- inferior vena cava
- circumflex artery
- a "inside the heart" is a glistening white sheet of endothelium (squamous epithelium) resting on a thin connective tissue layer. Located on the inner myocardial surface, it lines the heart chambers and covers the fibrous skeleton of the valves.
- b supplies the left atrium and the posterior walls of the left ventricle.
- c the double walled sac surrounding the heart.
- d returns blood from body regions inferior to the diaphragm. (lack oxygen.
- e also known clinically as the left anterior descending artery: follows the anterior interventricular sulcus and supplies blood to the interventricular septum and anterior walls of both ventricles;
5 Multiple choice questions
- Purkinje fibers (Purkyne tissue or Subendocardial branches) are located in the inner ventricular walls of the heart, just beneath the endocardium. These fibers are specialized myocardial fibers that conduct an electrical stimulus or impulse that enables the heart to contract in a coordinated fashion.
- returns blood from body regions superior to the diaphragm. (lack oxygen)
Drainage: Head, Upper limbs, etc.
- collects blood draining from the myocardium
5 True/False questions
Where is the pericardium found and what kind of tissue is it? → The pericardium (from the Greek περι, "around" and κάρδιον, "heart" /perikardion/) is a double-walled sac that contains the heart and the roots of the great vessels.
There are two layers to the pericardial sac: the fibrous pericardium and the serous pericardium.
pectinate muscles → conelike, play a role in valve function, project into the ventricular cavity.
coronary circulation → the functional blood supply of the heart, is the shortest circulation in the body.
pulmonary veins →
Origin: Right ventricle; Distributes to the lungs; pumps oxygen-poor blood from right ventricle; has the pulmonary valve at its origin.
fibrous pericardium → tough, dense connective tissue layer protects the heart, anchors it to surrounding structures, and prevents overfilling of the heart with blood.
