Pericardium/Heart Wall
The outer layer of the heart wall
What is Epicardium
The Greek word for heart
What is Kardia
These arteries supply the myocardium
What are the coronary arteries
Contains pacemaker cells and sets the fundamental rhythm of the heart
What is SA node (sinoatrial node)
The coronary veins drain into the RA via:
What is Coronary sinus
This structure anchors the fibrous pericardium to the diaphragm
What is the central tendon of the diaphragm
The muscle fibers of the heart are multi-diagonal and multi-directional for what purpose
To ensure strong, rhythmic contractions in unison
Name the semilunar valves of the heart AND how many cusps each?
What are Pulmonary and Aortic semilunar valves; 3
Guard your heart with all vigilance, for....
from it flow the springs of life
These two arteries branch off the inferior portion of the ascending aorta
What are R and L coronary arteries
This layer/structure also lines the great vessels and serves as an anchor
What is Fibrous pericardium
The purpose of compressions in CPR is to
What is force blood out of the heart into circulation
When papillary muscles are relaxed, chordae tendineae are
What is slack
Order of electrical signal/conduction of heart
What is SA Node, AV Node, Bundle of His, R/L Bundle branches, Purkinje fibers
All head and neck veins drain into these structures?
which then joins to form which great vessel?
R & L brachiocephalic veins
SVC
An inflammation of this layer usually occurs as a complication of a viral infection, rheumatic fever, or radiation, chemical or medicinal exposure. severe cases lead to cardiac failure and death.
What is Myocarditis
The heart and the root of the great vessels are found here (be very specific)
What is the middle inferior mediastinum
Pillar/finger-like projections in ventricular walls that pull chordae tendineae taut to prevent prolapse of blood back into atria
What are papillary muscles
Opening in the atrial septum to allow baby's blood to bypass mom's pulmonary circulation
What is foramen ovale
The two branches off the common carotid arteries are:
What is ICA, ECA
An inflammation of this layer usually involves heart valves and is usually caused by bacterial infections; s/s may include fever, heart murmur, arrhythmias, tachycardia, night sweats, chills; usually treated w/IV antibx.
What is Endocarditis
Vagus nerve is in this part of the mediastinum
What is the posterioinferior mediastinum
The Posterior interventricular coronary artery is a branch off this vessel
What is the Right Coronary Artery
If some fetal blood flows from RA to RV, this structure directs it to directly from PT to Aorta
What is ductus arteriosus
The right vertebral artery is ultimately branched off which one of the arteries branched off the arch of aorta
What is brachiocephalic
