Gastrointestinal smooth muscle, in regions like the stomach. Contractions, on the other hand, provide the propulsive force which moves digesta along the gastrointestinal tract, and additionally ensures adequate mixing of ingested material with digestive enzymes, and continuously brings nutrients into contact with the absorptive mucosal surface.

Intramural ganglia and mechanism of peristalsis,utonomic nervous system and contributes to the contractile activity seen .. The myogenic properties can only be seen when conduction in the intramural nerves is blocked chemically by treating with tetrodotoxin or physically by separating the muscle from the ganglia.

Neurocrines, endocrines and paracrines, additional route lies midway between neurotransmitter and hormone and is provided by substances which are released into the interstitial space and act as ‘local hormones’ or ‘paracrines’ (Figure 4.1).

The large intestine,re, the caecum is enlarged and more complex than in the carnivore, whose digestive processes are more or less complete before the digesta leaves the ileum, so consequently the carnivore colon is short and simple.

The coordination of gastrointestinal motility: the fed state, have not passed through the pylorus. The changeover, from MMC activity to continuous postprandial activity, occurs almost immediately after the ingestion of food and is maintained for 4–5 hours in man and for much longer in the dog.

C. Tabouret-Viaud,A. Baskin,P. Loubeyrethe oesophagus is closed by sphincters at both ends. The upper oesophageal sphincter is constricted so that air is prevented from entering the oseophagus during inspiration while tone in the lower oesophageal sphincter minimizes the reflux of acidic gastric contents.
