(11) Eating was associated with an increase in flow of the fluid and dry matter fractions of digesta passing from the omasum but efflux was unaffected by rumination.

(14) Samples of the following parts of the gastrointestinal tract were collected from 20 slaughter cattle: - oesophagus, reticulum, omasum, rumen, abomasum, duodenum, jejunum, ileum, colon (beginning and end).
(15) Specimens were obtained from the lung, omasum and Peyer's patches of the ileum and corresponding lymph nodes.
(16) Four ruminating bull calves were provided with cannulas in the rumen and abomasum and a sleeve sutured at the omosal-abomasal orifice that permitted digesta flowing from the omasum to be diverted and collected.
(17) Calves were slaughtered, and samples of the contents of the reticulo-rumen, omasum, abomasum, small intestine, cecum, and large intestine were analyzed for chromic oxide, copper, and manganese.
(18) The data concerning the transport of sodium and chloride in the omasum are very limited.
(19) The curves were analysed on the assumption that the stomach of the sheep could be represented as two mixing compartments (reticulo-rumen and abomasum) and a time delay (omasum).
(20) The following activities of GDH and GS were found out in trials with lambs at the age of 10, 20, 30, 40 and 90 days, as to the different parts of digestive tract: in the tissues of rumen, omasum, reticulum, spleen, duodenum, jejunum, ileum, int.
Psalterium
Definition:
(n.) The third stomach of ruminants. See Manyplies.
(n.) The lyra of the brain.
Example Sentences:
(1) All of these AChE positive fibers appeared to be related to the medial portions of the dorsal hippocampus from its septal pole to the dorsal psalterium.
(2) A similarly organized projection courses via the dorsal psalterium (dorsal hippocampal commissure) to the contralateral entorhinal area.
(3) Primary lesions of the dorsal psalterium alone had only slight and transient effects on alternation performance, however.
(4) The degeneration resulting from transection of the psalterium ventrale was most dense in the septal tip and decreased towards the temporal tip.
(5) A conspicuous septo-termporal gradient was found of the density of the commissural projection that passes through the psalterium ventrale to the Ammon's horn.
(6) Double-shock experiments showed that impulses of hippocampal origin inhibited the response to dorsal psalterium volleys of entorhinal neurons giving origin to perforant path fibers.
(7) Perforant path volleys, synaptically elicited by stimulation of the dorsal psalterium of one side, were used to activate the lamellar circuit of the same side and, through interhippocampal impulses, the hippocampal pyramidal neurons of the opposite side.
(8) Synaptic effects evoked in the entorhinal area by dorsal hippocampal commissure (dorsal psalterium) projections were analysed in anesthetized adult guinea-pigs by means of a field potential analysis.
(9) Perforant path volleys, synaptically elicited by stimulation of the dorsal psalterium of one side, were used to activate the hippocampal lamellar circuit of the same side and, through interhippocampal impulses, the hippocampal pyramidal neurons of the contralateral side.
(10) The fibers with the fastest mean conduction rate were found responsible for the excitatory synaptic effects evoked in the entorhinal area by dorsal psalterium stimulation, demonstrated by previous studies.
(11) Causal relations were observed between the entorhinal monosynaptic response and that evoked by dorsal psalterium stimulation in the ipsilateral dentate gyrus, previously shown to be relayed by perforant path fibers.
(12) The electrophysiological characteristics and the laminar distribution of the slow wave and of the spike potential, together with the presence of time-locked unit activity, suggested that dorsal psalterium projections evoke monosynaptic excitatory postsynaptic potentials leading to cellular discharge in radially oriented neurons of layers II and III.
(13) The three groups of fibers did not travel in separate bundles within the dorsal psalterium and were arranged in parallel fashion.
(14) The dorsal psalterium (the dorsal hippocampal commissure) of the guinea pig was electrophysiologically studied with a view to possible commissural fiber groups and their properties.
(15) In addition, secondary lesions of the dorsal psalterium (the fiber tract which carries the corssed E.C.-dentate projections) also disrupted performance in operated-recovered animals.
(16) Stimuli applied to the caudal part of the dorsal psalterium evoked a complex response in the dorsal third of the entorhinal area.
