QuestionAnswer
the endothelial lining of all of the chambers of the heart
this node lies in the interatrial septum
heart sound heard as blood passes through the atria to the ventricle
innervation of the diaphragm
these structure prolong ribs and contribute to elasticity of the thoracic wall.
parasympathetic innervation of the heart is supplied by which nerve?
posterior blood supply of the thorax comes from
Anterior intercostal arteries arise from which artery
escape of fluid into the pleural cavity
Which valves would be open during ventricular systole?
interference with venous return of blood to the heart due to an extensive accumulation of fluid in the pericardium (pericardial effusion)
union of subclavian & internal jugular veins create which vein?
the visceral and parietal plurae are continuous at the ...?
inferior boundary of the thoracic cavity
the internal thoracic artery arises from which artery?
the left 2nd intercostal space is the auscultation point for which valve?

arterial supply of the pericardium
the visceral layer of the serous pericardium
entry of air into the pleural cavity resulting from penetrating wound to parietal pleura

known as the pacemaker of the heart
heart sounds heard as blood is pumped from the ventricles.
The thoracic wall is innervated by:
each lobar bronchi divides into
each main bronchi divides into
occurs if a sufficient amount of air enters the pleural cavity causing the tension adhering visceral to parietal pleura to break
the left 4th intercostal space (just lateral to the sternum) is the auscultation point for which valve?
TRUE OR FALSE: The sympathetic innervation of the esophageal vascular smooth muscle is from the thoracic portion of the sympathetic chain and the fibers are postsynaptic.
an area of necrosis resulting from a sudden insufficiency of arterial or venous blood supply to the heart's muscular wall
surgical creation of an opening through the thoracic wall to enter a pleural cavity

the thick muscle layer of the heart
inflitration of anesthetic around intercostal nerves.
