The thoracic wall is innervated by:
Because of its angle with the trachea and size of the main bronchus, a bronchoscope would pass more readily into which lung?
this pleura covers the lungs and is adherent to all its surfaces
union of subclavian & internal jugular veins create which vein?
which artery accompanies the phrenic nerve?
the progressive narrowing and hardening of the arteries over time
Parasympathetic stimulation of the esophagus results in the rhythmic contraction of esophageal smooth muscle known as?

a surgical procedure in which an incision is made opening the chest cavity
aspiration of a foreign body usually falls into which mainstem?
anterior rami of T1-T11 form which nerves
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?
heart sounds heard as blood is pumped from the ventricles.
the right 2nd intercostal space is the auscultation point for which valve?
accumulation of a significant amount of fluid in pleural cavity
ANTERIOR VAGAL TRUNK of the esophagus is form from the left or right vagus nerve?
indents the anterioinferior aspect of the left lung
the left 2nd intercostal space is the auscultation point for which valve?
the thick muscle layer of the heart
failed closure of the foramen ovalis leads to?
midline incision through the sternum
obstruction of a pulmonary artery by a blood clot
These intercostal muscles help elevate ribs during inspiration
heart sound heard as blood passes through the atria to the ventricle
Blockage of which artery would lead to ischemia of the apex of the heart?
these intercostal muscles help depress the ribs during expiration
The portion of the parietal pleura that extends above the first rib is called the :
Which chamber's anterior wall forms most of the sternocostal surface of the heart?
parasympathetic innervation of the heart is supplied by which nerve?
an area of necrosis resulting from a sudden insufficiency of arterial or venous blood supply to the heart's muscular wall
electric impulses of the heart originate here..
the endothelial lining of all of the chambers of the heart
Which valves would be open during ventricular systole?
a keel-shaped cartilage lying at the tracheal bifurcation--it separates the right main stem bronchus from the left main stem bronchus.
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.
narrowing of the orifice of the aortic valve or of the supravalvular or subvalvular regions
a chronic disorder characterized by hyperreactive airways leading to episodic, reversible bronchoconstriction due to an increased sensitivity to irritating stimuli.
Anterior intercostal arteries arise from which artery
Difficult breathing
inflitration of anesthetic around intercostal nerves.
interference with venous return of blood to the heart due to an extensive accumulation of fluid in the pericardium (pericardial effusion)
the backflow of blood from ventricle to atrium
Which ribs have cartilages that do not attach to the sternum?
compensatory circulation carried on through secondary channels after obstruction of the principal vessel supplying the part
which nerve loops near the ligamentum arteriosum?
A viral disease of spinal ganglia and is a dermatomically distributed lesion...
insertion of a needle through an intercostal space in order to obtain pleural fluid
Which ribs attach directly to the sternum through their own costal cartilages?
this pleura lines the pulmonary cavities, adhering to the pulmonary wall
Stimulation of the sympathetic nervous system in the heart will cause...?
escape of fluid into the pleural cavity
Heart rate does what in the presence of parsympathetic stimulation?
each main bronchi divides into
main vein of the heart
entry of air into the pleural cavity resulting from penetrating wound to parietal pleura
Stimulation of the parasympathetic nervous system in the lungs acts to
the left 4th intercostal space (just lateral to the sternum) is the auscultation point for which valve?
injury to which nerve can cause paralysis of the diaphragm
surgical creation of an opening through the thoracic wall to enter a pleural cavity
A ventricular septal defect (VSD) usually affects which portion of the interventricular septum?
The sympathetic innervation of the heart originates from which part the thoracic spinal cord?
the visceral layer of the serous pericardium
occurs if a sufficient amount of air enters the pleural cavity causing the tension adhering visceral to parietal pleura to break
The sternocostal surface of the heart is formed primarily by the anterior wall of which heart chamber?
the posterior intercostal arteries arise from which artery?
innervation of the diaphragm
arterial supply of the pericardium
This collection of autonomic fibers is located at the base of the heart behind and within the concavity of the arch of the aorta.
The pleural cavity near the cardiac notch is known as the:
left and right brachiocephalic veins drain into?
left lung has how many lobes?
the brachiocephalic veins drain into which vein?
ligament that is a continuity between the pleural and parietal cavities that extends between parietal and mediastinum
known as the pacemaker of the heart
posterior blood supply of the thorax comes from
inferior boundary of the thoracic cavity
chest pain due to ischemia of the heart is known as
internal thoracic artery arise from which artery?
right lung has how many lobes?
each lobar bronchi divides into
these structure prolong ribs and contribute to elasticity of the thoracic wall.
this node lies in the interatrial septum
the internal thoracic artery arises from which artery?
POSTERIOR VAGAL TRUNK of the esophagus is form from the left or right vagus nerve?
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

ventricular relaxation, elongation, or extension
roots for the phrenic nerve
