QuestionAnswer
The sternocostal surface of the heart is formed primarily by the anterior wall of which heart chamber?
the endothelial lining of all of the chambers of the heart
The thoracic wall is innervated by:
left and right brachiocephalic veins drain into?
main vein of the heart
inflammation of the pericardium

the left 5th intercostal space (right below the nipple) is the auscultation point for which valve?
midline incision through the sternum
each lobar bronchi divides into
a keel-shaped cartilage lying at the tracheal bifurcation--it separates the right main stem bronchus from the left main stem bronchus.
injury to which nerve can cause paralysis of the diaphragm
contraction of the ventricles
parasympathetic innervation of the heart is supplied by which nerve?
compensatory circulation carried on through secondary channels after obstruction of the principal vessel supplying the part
the left 2nd intercostal space is the auscultation point for which valve?
posterior blood supply of the thorax comes from
innervation of the diaphragm
the visceral and parietal plurae are continuous at the ...?
right lung has how many lobes?
Parasympathetic stimulation of the esophagus results in the rhythmic contraction of esophageal smooth muscle known as?
which lung has the cardiac notch?
which nerve loops near the ligamentum arteriosum?
Which chamber's anterior wall forms most of the sternocostal surface of the heart?
which bronchi is shorter and wider and more vertical.
this node lies in the interatrial septum
This collection of autonomic fibers is located at the base of the heart behind and within the concavity of the arch of the aorta.
this pleura covers the lungs and is adherent to all its surfaces
union of subclavian & internal jugular veins create which vein?
the visceral layer of the serous pericardium
The pleural cavity near the cardiac notch is known as the:
heart sounds heard as blood is pumped from the ventricles.
Heart rate does what in the presence of parsympathetic stimulation?
ventricular relaxation, elongation, or extension
QuestionAnswer
which artery accompanies the phrenic nerve?
a chronic disorder characterized by hyperreactive airways leading to episodic, reversible bronchoconstriction due to an increased sensitivity to irritating stimuli.
inflitration of anesthetic around intercostal nerves.
the left 4th intercostal space (just lateral to the sternum) is the auscultation point for which valve?
each main bronchi divides into
heart sound heard as blood passes through the atria to the ventricle
Because of its angle with the trachea and size of the main bronchus, a bronchoscope would pass more readily into which lung?
the right 2nd intercostal space is the auscultation point for which valve?
roots for the phrenic nerve
the posterior intercostal arteries arise from which artery?
Which ribs have cartilages that are joined to the cartilage just superior to them (indirect attachment to sternum)?
Stimulation of the sympathetic nervous system in the heart will cause...?
Blockage of which artery would lead to ischemia of the apex of the heart?
the progressive narrowing and hardening of the arteries over time
the brachiocephalic veins drain into which vein?
electric impulses of the heart originate here..
Which valves would be open during ventricular systole?
ANTERIOR VAGAL TRUNK of the esophagus is form from the left or right vagus nerve?
Stimulation of the parasympathetic nervous system in the lungs acts to
the main arterial supply for the pericardium
the internal thoracic artery arises from which artery?
accumulation of a significant amount of fluid in pleural cavity
obstruction of a pulmonary artery by a blood clot
left lung has how many lobes?
entry of air into the pleural cavity resulting from penetrating wound to parietal pleura
inflammation of the endocardium
failed closure of the foramen ovalis leads to?
this node is located in the cristae terminalis of the right atrium
the pec. major, pec. minor, and serratus anterior muscles can help expand the thoracic cavity when inspiration is deep and forceful. These muscles are what type of muscles?
The sympathetic innervation of the heart originates from which part the thoracic spinal cord?
known as the pacemaker of the heart
insertion of a needle through an intercostal space in order to obtain pleural fluid
inferior boundary of the thoracic cavity
surgical creation of an opening through the thoracic wall to enter a pleural cavity
QuestionAnswer
internal thoracic artery arise from which artery?
where does rib 2 attach?
an area of necrosis resulting from a sudden insufficiency of arterial or venous blood supply to the heart's muscular wall
ligament that is a continuity between the pleural and parietal cavities that extends between parietal and mediastinum
anterior rami of T1-T11 form which nerves
Which ribs have cartilages that do not attach to the sternum?
Difficult breathing
A ventricular septal defect (VSD) usually affects which portion of the interventricular septum?
occurs if a sufficient amount of air enters the pleural cavity causing the tension adhering visceral to parietal pleura to break
indents the anterioinferior aspect of the left lung
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.
interference with venous return of blood to the heart due to an extensive accumulation of fluid in the pericardium (pericardial effusion)
arterial supply of the pericardium

Which ribs attach directly to the sternum through their own costal cartilages?
this pleura lines the pulmonary cavities, adhering to the pulmonary wall
these structure prolong ribs and contribute to elasticity of the thoracic wall.
a surgical procedure which involves replacing diseased (narrowed) coronary arteries with veins obtained from the patient's lower extremities or the patient's internal thoracic arte
a surgical procedure in which an incision is made opening the chest cavity
muscles of the right ventricle are known as
narrowing of the orifice of the aortic valve or of the supravalvular or subvalvular regions
