Receiving Function

The Common Vein copyright 2007

Principles

There is a continual process of receiving processing and exporting that sometimes is only for a moment in time as food get passed down the esophagus for example or an electric impulse gets passed down a nerve or muscle.  In the grand and larger scheme there are certain recognizable events such as the afferent system of the nervous system where the receiving process is more discrete.  The brain and spinal cord are geared toward receiving the sensory impulses from the afferent system and the the left atrium and right atrium are geared toward receiving the systemic and pulmonary venous systems.  In these instsances the receiving function becomes clear.  At a cellular level there are specific receptors on the cell membrane that work like a lock and key to switch on or switch off a process.  This receiving function is highly discrete and recognizable.

Cardiovascular System

Receiving Chambers of the Heart Left Atrium and Right Atrium

These two images are enhanced CT images through the tricuspid valve. The first image is normal, while the second image demonstrates a TV that lies too far forward and low associated with a huge RA and a diminutive RV. This appearance is classical of a congenital condition called Ebstein’s anomaly. In this disease, the posterior leaflet is stuck down to the posterior wall of the RV and the anterior leaflet is larger than normal often giving a flapping sound to the listening ear. The anterior leaflet behaves like a flapping sail in the wind of the blood flow. Can you identify RA and TV? – see next image if you need help.Courtesy of Ashley Davidoff M.D. 32101 code heart right atrium (RA) coronary sinus fx enlarged box shape lung pulmonary congestion dx dx Ebsteins anaomaly cardiac imaging radiology CTscan Courtesy Ashley Davidoff MD
