“…'Catch' has also been used to describe observations similar to those first made by Blaschko et al (1931) in which single spikes or brief trains of high frequency spikes inserted into tonic low frequency spike trains result in a long-lasting increases in muscle contraction amplitude (invertebrate examples: Wilson and Larimer, 1968;Wilson et al, 1970;Wakabayashi and Kuroda, 1977;Burns and Usherwood, 1978;vertebrate examples: Lee et al, 1999a,b;Van Lunteren and Sankey, 2000). This clearly differs from molluscan catch in that nerve stimulation and actomyosin activation occur throughout the contraction.…”

This is the second in a series of canonical reviews on invertebrate muscle. We cover here thin and thick filament structure, the molecular basis of force generation and its regulation, and two special properties of some invertebrate muscle, catch and asynchronous muscle. Invertebrate thin filaments resemble vertebrate thin filaments, although helix structure and tropomyosin arrangement show small differences. Invertebrate thick filaments, alternatively, are very different from vertebrate striated thick filaments and show great variation within invertebrates. Part of this diversity stems from variation in paramyosin content, which is greatly increased in very large diameter invertebrate thick filaments. Other of it arises from relatively small changes in filament backbone structure, which results in filaments with grossly similar myosin head placements (rotating crowns of heads every 14.5 nm) but large changes in detail (distances between heads in azimuthal registration varying from three to thousands of crowns). The lever arm basis of force generation is common to both vetebrates and invertebrates, and in some invertebrates this process is understood on the near atomic level. Invertebrate actomyosin is both thin (tropomyosin:troponin) and thick (primarily via direct Ca ++ binding to myosin) filament regulated, and most invertebrate muscles are dually regulated. These mechanisms are well understood on the molecular level, but the behavioral utility of dual regulation is less so. The phosphorylation state of the thick filament associated giant protein, twitchin, has been recently shown to be the molecular basis of catch. The molecular basis of the stretch activation underlying asynchronous muscle activity, however, remains unresolved.

“…Earlier work has shown that the hysteretic catch-like effect is mainly observed under non-isometric conditions of force measurement (Blaschko et al, 1931;Wilson et al, 1970). Nonetheless supposedly isometric conditions were used in most investigations of the effect (Blaschko et aI., 1931;Wilson & Larimer, 1968;Wakabayashi & Kuroda, 1977;Evans & Siegler, 1982;Hoyle, 1984). According to the hypothesis presented here, no catch-like effect should be observed under truly isometric conditions.…”

“…The above results lead to the hypothesis that the catch-like effects described for arthropod muscles (Blaschko et al, 1931;Edwards et al, 1964;Wilson & Larimer, 1968;Wilson et al, 1970;Smith, 1975;Wakabayashi & Kuroda, 1977;Bums & Usherwood, 1978;Hawkins & Bruner, 1979;Evans & Siegler, I982) might be related to the creep and the residual force enhancement known from vertebrate muscles (Gordon et al, 1966;Edman et al, 1978Edman et al, , 1982ter Keurs et al, 1978;Julian & Morgan, I979a, b;Altringham & Bottinelli, 1985;Morgan, 1990). A possible explanation discussed for these two phenomena is based on the fact that a muscle fibre can only be stable during force development if each sarcomere in series produces an identical amount of force (Gordon et al, 1966;Julian & Morgan, 1979a, b;Morgan, 1990;Saldana & Smith, 1991).…”

“…These phenomena can roughly be divided into two groups. One group consists of hysteresis phenomena, which occur either after a brief intermittent increase in the frequency of repetitive stimulation (Blaschko et al, 1931;Wilson & Larimer, 1968;Wilson et al, 1970;Smith, 1975;Wakabayashi & Kuroda, 1977;Bums & Usherwood, 1978;Evans & Siegler, 1982;present investigation), or after a sinusoidal change of the stimulation frequency (Wilson & Latimer, 1968;Wilson et al, 1970;Evans & Siegler, 1982). The second group comprises various effects on the resting tension of a muscle, often mediated by neuro-hormones (Hawkins & Bruner, I979;Chestler & Fourtner, 1981;Hoyle & Field, 1983;Hoyle, 1984) and has not been considered in the present paper.…”

“…The muscle appears to maintain an increased force without additional expenditure of energy. Subsequently this type of hysteresis, termed Blaschko, Catell, Kahn effect, has been found in a number of arthropod muscles (Edwards et al, 1964;Wilson & Larimer, 1968;Wilson etal., 1970;Smith, 1975;Wakabayashi & Kuroda, 1977;Bums & Usherwood, 1978;Hawkins & Bruner, 1979;Chesler & Fourtner, 1981;Evans & Siegler, 1982;Hoyle & Field, 1983;Hoyle, 1984).…”

Non-uniformity of sarcomere lengths can explain the ?catch-like? effect of arthropod muscle

The 'catch-like' effect, a hysteresis phenomenon in arthropod skeletal muscle contraction thought to be related to the catch of molluscan smooth muscle, was investigated in the closer muscle of the crab Eriphia spinifrons. Several parameters were varied to determine their influence on the catch-like effect. These parameters were (1) the frequency of repetitive stimulation of the slow excitatory neuron, (2) additional stimulation of the inhibitory neuron, (3) the amount of stretch applied to the muscle and (4) the stiffness of the mechano-electrical transducer. The results show that the catch-like effect is not related to the catch of molluscan smooth muscle but rather to the 'residual force enhancement' or 'creep' phenomenon described for vertebrate muscle. A hypothesis for residual force enhancement implies that the increase in force is caused by non-uniformity of sarcomere lengths along the muscle fibre. Based on this hypothesis and the actual force-length relationship of the crab muscle studied, calculations were carried out to determine, if the observed catch-like effect can be explained by such a model. The calculations corroborate the experimental evidence. The catch-like effect of arthropod muscles can thus be explained by the same mechanism responsible for residual force enhancement and creep in vertebrate muscle. A physiological relevance of the catch-like effect in arthropod muscle is inferred.

The effects of doublet impulse sequences of the excitatory motor axon on the movement of the claw opener muscles in the crayfish were examined. The excitatory motor axon was stimulated electrically with various patterns of doublet impulse sequences generated by a digital computer. Doublet impulse sequences of stimulation produced a larger sustained movement than an uniform impulse sequences at the same mean rate of stimulation. The movement was largest when the interval between the impulses of a doublet was about 5 ms. This interval generated a movement amplitude 25% greater than that for the uniform impulse sequence. A simple model was formulated to stimulate the neuromuscular synapse of the claw opener muscle. The relationship between stimulation sequences with alternating long and short intervals and responses (firing probabilities) of the neuromuscular synapse at the same mean rate was investigated. The responses was classified into two typical types which are noneffective Type I and effective Type II to the absolute refractory period (ARP). The characteristics which are larger responses with short intervals in Type I and reduction of responses in the ARP region of Type II formed a plateau peak of the experimental results. By incorporating the reduction of end-plate potential (EPP) as a property of nonlinear rule for temporal summation into the model, it was shown that Type I response is maximal with a plateau peak at short interval, agreeing well with the experimental results from the claw opener muscles.
