39 2 Control of the Reticulo-Omasal Orifice and Related S t r u c t u r e s Another difference of activity of the reticulo-omasal orifice in fed as opposed to fasted lambs is that small-burst activity continues after comĀ­ bined administration of atropine, phentolamine, and hexamethonium (Reid and Titchen 1986). This suggets that excitation of the orifice postprandially is contributed to by either 1. Alterations in the degree of inhibitory input to the reticulo-omasal orifice; 2. The stimulation by feeding of a reflex neural pathway (extrinsic or intrinsic) excitatory to the reticulo-omasal orifice, which does not involve nicotinic transmission at ganglia or acetylcholine or noradrenalin as the neuromuscular transmitter; or 3.
