Lobster arteries, which exhibit non-uniform elasticity when stretched, have a trilaminar organization. The inner layer is an elastic connective tissue and the outer layer is a collagenous connective tissue; the middle layer of an artery is an aggregation of cells containing microfilaments. Arterial cells possess actin, myosin and tropomyosin. Except for the dorsal abdominal artery, striated mus...

The pacemaker ganglion of the lobster heart is a functionally complete neural structure of nine cells which is capable of spontaneously producing bursts of actionpotential discharges separated by periods of relative inactivity. The burst discharge is maintained even when the ganglion is completely removed from the heart. The somata of five of the nine cells are quite large, approximately 60 /i ...

Crustacean crustacyanin proteins are linked to the production and modification of carapace colour, with direct implications for fitness and survival. Here, the structural and functional properties of the two recombinant crustacyanin subunits H(1) and H(2) from the American lobster Homarus americanus are reported. The two subunits are structurally highly similar to the corresponding natural apo ...

The stomach of the American lobster (Homarus americanus) is located in the cephalothorax, between the rostrum and the cervical groove. The anterior end of the stomach is defined by the mouth opening and the posterior end by the bottom of the pylorus. Along the dorsal side of the stomach lies the stomatogastric nervous system (STNS). This nervous system, which contains rhythmic networks that und...

Parasitic dinoflagellates of the genus Hematodinium infect several commercially important decapod crustaceans. Different species of Hematodinium have different levels of virulence in their respective hosts. Enzyme activities were studied from two species of Hematodinium, one isolated from the Norway lobster (Nephrops norvegicus) and the other from the American blue crab (Callinectes sapidus). W...

The effects of external calcium deprivation on certain characteristics of the action potential of the lobster motor axon have been studied. Upon exposure to calcium-free solution the spike amplitude is rapidly decreased within a few minutes and is followed by a slow linear decline. The rates of spike rise and fall are proportionally reduced more than the spike but follow similar time courses du...
