(19) In arthropods, reflex modulation can occur in the sensory receptors themselves and in neurons that discharge during locomotion.
(20) The inhibition assay for mite allergen was reproducible in the presence of protein concentrations of added plant, fungal, arthropod and animal extracts in excess of the protein concentrations that occur under the operational mite assay conditions.
Invertebrate
Definition:
(a.) Destitute of a backbone; having no vertebrae; of or pertaining to the Invertebrata.
(n.) One of the Invertebrata.
Example Sentences:

(3) This invertebrate precipitin, Tridacnin, may be used as a marker for nearly two thirds of all asialo serum glycoproteins; A number of different cross-reactions with various other polysaccharides and galactans subdivides those neuraminidase-treated glycoproteins into several subgroups, indicating that the uncovered carbohydrate structures are not always completely identical.
(4) We compared the molecular nature of the rat brain opiate receptor with that of the invertebrate leech, Haemopis marmorata, and the protozoan, Tetrahymena, in order to examine the issue of apparent receptor heterogeneity with respect to biochemical structure.

(10) The body wall muscle and the blood vessel muscle are compared with other muscle types described in invertebrates.
(11) Although neither protein bound to heparin, gelatin, hexosamine, or uronic acid-Sepharose resins, their affinity for an invertebrate proteoglycan, their roles in sponge cell adhesion, and their peripheral membrane protein natures suggest that they may represent early invertebrate analogs of cell-associated vertebrate extracellular matrix adhesion proteins, such as fibronectin or vitronectin, or else an entirely novel set of cell adhesion molecules.
