Veterinary Clinics of North America: Exotic Animal Practice, 2004
In this article, "Invertebrates" are considered to be all those animals that are not in the five main groups of vertebrates (Mammalia,Aves, Reptilia, Amphibia, and three classes of fish), and the term neoplasm is used in its traditional sense of "new, uncontrolled, growth".

Current Opinion in Neurobiology, 1993
Olfactory transduction in invertebrates seems to be similar to that in vertebrates. Three signalling systems involving activation of adenylate cyclase, phospholipase C and guanylate cyclase are present. A variety of second messengers, including cAMP, inositol 1,4,5-trisphosphate, diacylglycerol, nitric oxide and Ca2+, have been identified but their ...

Veterinary Clinics of North America: Exotic Animal Practice, 2020
Invertebrates are becoming more popular and, as collections age, clients may seek veterinary intervention where the welfare of the animal must be considered. This article covers aging in many invertebrate species but with a focus on species likely to be seen in general practice.

Invertebrates in neurotoxicology [PDF]
Acta Biologica Hungarica, 2000 Due to the relative simplicity of their nervous system, invertebrate animals were widely used in the past decades for studying the processes of excitability at membrane level, as well as the mechanisms of neuronal events and interneuronal communication. Parallel with investigating basic questions of neurobiology, lower animals have also been the object

Australian Journal of Experimental Biology and Medical Science, 1968
SummaryTwo species of invertebrates, Parachaeraps bicarinatus, a freshwater crayfish, and Helix pomatia, a garden snail, were examined for the presence of cells which could phagocytose particulate material introduced into their vascular systems. By means of blood clearance studies and histological techniques, it was demonstrated that there existed a ...

Masking effects are a common feature of daily rhythmicity in invertebrates; and, particularly with respect to activity/rest cycles in arthropods and mollusks, there are numerous examples of masking in response to external environmental stimuli. Internal masking, in which endogenous processes modulate circadian patterns, has also been documented in a ...

Octopamine (OA), a biogenic monoamine structurally related to noradrenaline, acts as a neurohormone, a neuromodulator and a neurotransmitter in invertebrates. It is present in relatively high concentrations in neuronal as well as in non-neuronal tissues of most invertebrate species studied. It functions as a model for the study of modulation in general.

Publisher Summary The chapter discusses the viruses of invertebrates. The great majority of the viroses described among the invertebrates occur in the Insecta. In the Lepidoptera, newly found nuclear polyhedroses, intestinal cytoplasmic polyhedroses, and granuloses have been added to the list of inclusion body viroses.

GnRH in the invertebrates: an overview
2002Publisher Summary This chapter provides an overview of GnRH in the invertebrates. The gonadotropin-releasing hormone (GnRH), which was previously called luteinizing hormone-releasing hormone (LHRH), represents a pivotal peptide in animal reproduction.

Lamins are the main component of the nuclear lamina and considered to be the ancestors of all intermediate filament proteins. They are localized mainly at the nuclear periphery where they form protein complexes with integral proteins of the nuclear inner membrane, transcriptional regulators, histones and chromatin modifiers.
