Plexus
Definition:
(pl. ) of Plexus
(n.) A network of vessels, nerves, or fibers.
(n.) The system of equations required for the complete expression of the relations which exist between a set of quantities.
Example Sentences:
(1) The inhibition was not seen in longitudinal muscle without myenteric plexus.

(5) In cancer of the pancreas head, cancer cells could invade the portal vein and perineural space of the celiac plexus, and metastasize to regional lymph nodes around the celiac axis.
(6) Because this transport system in the choroid plexus is normally responsible for the excretion of the serotonin metabolite from the brain to the plasma, accumulation of endogenously produced organic acids in the brain, secondary to reduced clearance by the choroid plexus, could be a contributing factor in the development of encephalopathy in children with medium-chain acyl-CoA dehydrogenase deficiency who have elevated levels of octanoic acid systematically.
(7) There was also a significant (P less than 0.001) improvement in clinician-assessed subjective and objective signs (bleeding, inflammation and dilatation of the haemorrhoidal plexus) after 2 and 4 weeks' treatment compared with placebo.
(8) For sequelae in the brain, nervous plexuses, heart, eye, surgical treatment can be useful, even if frequently with palliative results.
