[Spontaneous motility and contractile response of the sheep omasum (author's transl)]

Spontaneous motility of the sheep omasum longitudinal muscular layer its responses to the periarterial and transmural electric stimulus have been studied in vitro. Three parts of the organ were chosen: a) the greater curvatura; b) omasum lateral wall, and c) omasum canal. The preparations always showed a great spontaneous motility with elevated contractions followed by relaxations. The electric stimulation caused contractile responses followed by relaxation. The lesser the spontaneous motility, the greater becomes the response, which disappears when the spontaneous motility is very high.
