The cardiac sphincter in the cat

C G Clark, J R Vane
PMCID: PMC1413268  PMID: 13879670

Abstract

A study of the function of the lower end of the oesophagus in the cat confirms that it behaves as a true physiological sphincter, even though histological evidence for such a structure is absent. Sphincteric action is a function of the circular muscle fibres in the lowest 2 cm. of the oesophagus. Reflex changes in tone of the sphincter are mediated through the autonomic nervous system.

The effects of possible neurohumoral transmitters, nerve stimulation, and antagonists have been studied.
