Sensitivity to Light in the Sea Anemone Metridium Senile (l.)
1. The reaction time of the photosensitive response of Metridium was found to be composed almost entirely of a sensitization period. If a latent period exists, it is too short to be detected by the methods used and is probably less than a second in duration. The length of the reaction time, therefore, was used as a measure of the radiant energy necessary at any intensity to elicit a response. 2...
متن کاملThe organization of the muscular system of Metridium senile.
I . The muscular system of Metridium consists of fields of relatively short musclefibres. In extension these may exceed i mm. in length but are only about 0-5/* thick. They can shorten to about a fifth of the extended length. The fibres consist almost entirely of densely staining material. They form a connected network. At least in some cases the cells seem to be in contact rather than to form ...
متن کاملPhases of activity in the sea-anemone, Metridium senile (L.), and their relation to external stimuli.
We have shown in a previous paper (Batham & Pantin, 19506) that the sea-anemone Metridium senile exhibits continual very slow muscular activity. It is most evident in the changes of shape of the column caused by the reciprocal contractions of the circular muscle sheet, and of the longitudinal parietal musculature which runs at the junction of each mesentery with the body wall. This inherent act...
متن کاملSlow Contraction and Its Relation to Spontaneous Activity in the Sea-anemone Metridium Senile (l.)
It has been known for some time that the most rapid reflex contractions of seaanemones show a characteristic relation to the stimulus. Thus in CalUactisparasitica a short series of adequate electric shocks, given at a frequency of about 1 per sec, is regularly followed by a facilitated contraction of the marginal sphincter (Pantin, 1935a, b). That is, each successive shock sets up a nervous imp...
