(18) Absorption spectra of visual screening pigments obtained in vitro with a microspectrophotometer using frozen sections are given for the insects Musca domestica, Phormia regina, Libellula luctuosa, Apis mellifera (worker honeybee only), Drosophila melanogaster (wild type only) and the arachnids Lycosa baltimoriana and Lycosa miami.
(19) Arachnidism can be manifested either through the skin or systemically.
(20) Since guanine is not only an essential constituent of vital nucleic acids, but also the main end product of nitrogenous waste excretion in arachnids, it is a potential candidate for a hygienic index for mite activity in house dust.
Hypostome
Definition:
(n.) Alt. of Hypostoma
Example Sentences:
(1) The external surface of the hypostome possesses cnidocils, possibly sensory hairs, and small spiny protrusions surrounding the mouth; the internal surface has cylindrical microvilli, free flagella and adherent flagella.
(2) Additional observations on some fine structures of Demodex folliculorum under SEM were presented in this paper, including supracoxal spines, hypostome, palpal claws, male and female podosomal setae, leg claw-basal spur, femoral spur, etc.
(3) Nile-blue-stained cells from hypostome or peduncle did not form specific structures in the reconstructed polyp, but were distributed throughout the animal.
(4) A population of sensory nerve cells localized in the head (hypostome and tentacles) is identified by the binding of antibody JD1.
(5) The second was an antiserum against the peptide Arg-Phe-amide (RFamide), which in the head of hydra is specific to the sensory cells of the hypostomal apex and the ganglion cells of the lower hypostome and tentacles.
(6) The normal morphology of the hypostome and mouth of hydra were examined by transmission electron microscopy with conventional thin sections and freeze-fracture replicas.
(7) The same midpiece tissue differentiated to a basal disc when grafted near the host hypostome, and to a small hypostome with tentacles when grafted near the host basal disc.
(8) Myonemes of the hypostome are small in diameter, have gap and intermediate-type cell junctions within each epithelial layer and are associated with the opposite epithelial layer by transmesogleal processes and gap junctions.
(9) It is a distinct neuronal complex consisting of a thick nerve bundle running circumferentially at the border between the hypostome and tentacle zone.
(10) The anatomy and developmental dynamics of the nerve ring in the hypostome of Hydra oligactis were examined immunocytochemically with an antiserum against a neuropeptide and with neuron-specific monoclonal antibodies.
(11) The hypostome and tentacles regenerate as far as is allowed by actinomycine.
(12) The sex of D. silvarum nymphs can be identified by the width of gnathosoma, length of hypostome and diameter of peritreme.
