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