Flashcards in *Anatomy 1 Deck (48)
What makes up the lung root?
Pulmonary lymphatic vessels and bronchopulmonary lymph nodes
Pulmonary visceral afferents and autonomic motor nerves
Divisions of pericardium
Serous pericardium (divided into visceral serious pericardium and parietal serous pericardium)
What is epicardium another name for
Visceral serous pericardium (secretes pericardial fluid)
What happens if pericardial cavity fills with blood?
Treatment for this
Where is the needle inserted
Have haemopericardium and leads to a cardiac tamponade
Transverse pericardial sinus?
Space within the pericardial cavity posterior to ascending aorta and pulmonary trunk
Surfaces of the heart
Anterior (sternocostal) surface
Base (posterior) surface
Inferior (diaphragmatic) surface
What often shifts the apex beat to the left
What vessel sits in the coronary groove (coronary sulcus/ right atrioventricular groove)?
What does this groove mark?
Right coronary artery
The division between the right atrium and right ventricle (tricuspid valve)
Is the vagus nerve or phrenic nerve closer to the heart
What vessel lies in the anterior interventricular groove?
What does this groove indicate?
Left anterior descending artery
Boundary between the 2 ventricles
What sits in the posterior atrioventricular groove?
Purpose of this?
Receives deoxygenated blood from most of the cardiac veins and drains into the right atrium
What normally sits in the posterior interventricular groove?
Posterior interventricular artery
Posterior interventircular vein
Where does the azygous vein drain?
What does the interatrial groove indicate
Boundary between the 2 atria
What does the coronary arteries do?
Provide an arterial blood supply to the myocardium and epicardium (located just deep to the epicardium usually embedded in adipose tissue)
Where do the coronary arteries arise?
From the ascending aorta
What normally forms between the right coronary artery and the circumflex artery
A small anastomose
Grooves of the heart (5)
left atrioventricular grove
anterior interventricular groove
posterior interventiruclar groove
2 parts of the septum?
Interatrial septum (interatrial groove)
Interventricular septum (interventricular groove)
Where is the hole in an atrial septal defect and a ventricular septal defect?
What blood vessels open into the right atrium?
Smooth ridge of muscle in the lateral aspect of the RA which represents the junction between the sinus venosus and the heart
an oval depression on the lower part of the septum of the right atrium; it is a vestige of the foramen ovale, and its floor corresponds to the septum primum of the fetal heart;
Tricuspid valve cusps?
Anterior, posterior and septal
Pulmonary valve cusps
Anterior right and left
Aortic valve cusps
Right left and posterior
Anterior and posterior
Which valve has sinuses (spaces within he cusps)
Which sinuses does the coronary arteries arise from
Right and left aortic sinuses
