(16) The ROC comprises rapidly propagating bursts of spike potentials (SPBs) that occur in a regular and predictable pattern: single orad SPBs alternate with groups of aborad SPBs.
(17) These were directed in an aborad direction from 7 to 9 a.m. and from 9 p.m. to midnight.
(18) The sSWs were believed to be involved in regulation of antiperistalsis while the lSW were believed to be involved in regulation of the large contractions which, on the basis of the lSW frequency gradient, appeared to be peristaltic and to be primarily responsible for aborad movement of colonic digesta.
(19) The pacesetter potentials were paced electrically in a forward (aborad) or a reverse (orad) direction.
(20) Their motor equivalent is the giant contraction which migrates in the aborad direction at relatively high velocity.
Aboral
Definition:
(a.) Situated opposite to, or away from, the mouth.
Example Sentences:
(1) During the first 15 to 20 min of metamorphosis the larval arms are retracted and resorbed into the aboral surface of the juvenile.

(3) 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.
(4) In S. purpuratus, the Hbox1 gene product probably is not involved in initial specification of cell fate, as this message does not achieve a significant fraction of its peak abundance until almost hatching blastula stage, well after the time aboral ectoderm cells have initiated a tissue-specific program of gene expression.
(5) In rats sensitized by T. spiralis infection, mast cells were increased in number in the jejunum and the number of mast cells followed an aboral gradient down the entire length of the gut in continuity.
(6) In all the animals, enterokinase values were unequivocally the highest in the duodenal mucosa; in the other intestinal segments it displayed a marked aboral decrease, so that we found about 30% of duodenal activity in the jejunum, trace amounts in the ileum and zero values in the caecum and the sigmoid flexure.
(7) The CyIIIa and CyIIIb genes, which form a separate linkage group, are expressed only in aboral ectoderm and its precursors.
(8) Such spread occurred most commonly in an aboral direction and was usually accompanied by an exacerbation of symptoms, although spread occasionally occurred during apparently quiescent periods.
(9) Infusions of 1 and 4 mmol of HCl (pH 2.0) into the duodenal bulb of conscious sheep, within 30% of the period of the migrating myoelectric complex (MMC) cycle, induced aborally propagated premature phases of regular spiking activity (RSA) on the proximal duodenum.
(10) Short sequences of three to five long spike bursts were propagated either aborally or orally from any part of the colon; they were most frequent during the interdigestive or fasting period and no relationship was observed between these long spike bursts and the electrical activity of the ileum.
(11) CyIIIa is expressed only in aboral ectoderm lineages; the other genes studied were Spec1, also expressed in aboral ectoderm; CyI, expressed in many different cell types; and SM50, expressed only in skeletogenic mesenchyme.

(14) It is shown that only bipolar cells with small dendritic aborizations (less than or equal to 14 micron dia) take part in this organization.
(15) A similar proportion of regular (27.9%) and prolonged (31.2%) phasic waves propagated aborally along the ileum or from ileum to cecum.
(16) This is a case report on tuberculosis of the stomach in a 70-year-old woman who, submitted to an endoscopic examination for uncharacteristic upper abdominal complaints, revealed multiple ulcers in the aboral part of the stomach, together with a thickening of the gastric wall.
(17) Oral and aboral ends of terminal ileal and colonic segments, 17 cm in length, were connected to a propulsion evaluation system that imposed input-output conditions of constant capacitance and negligible resistance.
