electric impulses of the heart originate here..
innervation of the diaphragm
which nerve loops near the ligamentum arteriosum?
a chronic disorder characterized by hyperreactive airways leading to episodic, reversible bronchoconstriction due to an increased sensitivity to irritating stimuli.
This collection of autonomic fibers is located at the base of the heart behind and within the concavity of the arch of the aorta.
muscles in the wall of the right atrium are known as?
Which ribs attach directly to the sternum through their own costal cartilages?
known as the pacemaker of the heart
POSTERIOR VAGAL TRUNK of the esophagus is form from the left or right vagus nerve?
this node is located in the cristae terminalis of the right atrium
midline incision through the sternum
Stimulation of the sympathetic nervous system in the heart will cause...?
the thick muscle layer of the heart
posterior blood supply of the thorax comes from
arterial supply of the pericardium
ligament that is a continuity between the pleural and parietal cavities that extends between parietal and mediastinum
the left 5th intercostal space (right below the nipple) is the auscultation point for which valve?
which artery accompanies the phrenic nerve?
this pleura covers the lungs and is adherent to all its surfaces
each lobar bronchi divides into
the visceral and parietal plurae are continuous at the ...?
inferior boundary of the thoracic cavity
the left 2nd intercostal space is the auscultation point for which valve?
These intercostal muscles help elevate ribs during inspiration
accumulation of a significant amount of fluid in pleural cavity
Heart rate does what in the presence of parsympathetic stimulation?
Which valves would be open during ventricular systole?
escape of fluid into the pleural cavity
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?
Stimulation of the sympathetic nervous system in the lungs acts to
compensatory circulation carried on through secondary channels after obstruction of the principal vessel supplying the part
Which ribs have cartilages that do not attach to the sternum?
QuestionAnswer
injury to which nerve can cause paralysis of the diaphragm
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.
surgical creation of an opening through the thoracic wall to enter a pleural cavity
heart sound heard as blood passes through the atria to the ventricle
the right 2nd intercostal space is the auscultation point for which valve?
A ventricular septal defect (VSD) usually affects which portion of the interventricular septum?
Which chamber's anterior wall forms most of the sternocostal surface of the heart?
these structure prolong ribs and contribute to elasticity of the thoracic wall.
this node lies in the interatrial septum
contraction of the ventricles

inflammation of the endocardium
Blockage of which artery would lead to ischemia of the apex of the heart?
which bronchi is shorter and wider and more vertical.
the endothelial lining of all of the chambers of the heart
occurs if a sufficient amount of air enters the pleural cavity causing the tension adhering visceral to parietal pleura to break

where does rib 2 attach?
The sympathetic innervation of the heart originates from which part the thoracic spinal cord?
ventricular relaxation, elongation, or extension
a keel-shaped cartilage lying at the tracheal bifurcation--it separates the right main stem bronchus from the left main stem bronchus.
Stimulation of the parasympathetic nervous system in the lungs acts to
the brachiocephalic veins drain into which vein?
these intercostal muscles help depress the ribs during expiration
Which ribs have cartilages that are joined to the cartilage just superior to them (indirect attachment to sternum)?
union of subclavian & internal jugular veins create which vein?
failed closure of the foramen ovalis leads to?
