Motor events in equine large colon.


Journal Article

The equine large colon is the major cellulose-fermentation locus of these species. The area of juncture of the ventral and dorsal divisions of the equine large colon was characterized, in 13 chronic unanesthetized animals and in 25 in vitro preparations, as an area of resistance to aboral flow. This is a probable pacemaker area. The reservoir function of this part of the colon is apparently facilitated by the presence of a pacemaker at this level. There was a general rise in recorded intraluminal pressure peaks during the first hour of feeding. This characteristic was not altered after resection of the extrinsic nerve supply. Electrical stimulation of the extrinsic nerve net in conscious animals at times mimicked the groups of intraluminal pressure peaks seen at the beginning of feeding.
