Ants of the ponerine genus Odontomachus use a trap jaw mechanism when hunting fast prey. When particular trigger hairs, located on the inner edge of the mandibles, are touched by prey, the jaws close extremely rapidly and trap the target. This trap jaw response lasts only 0.33 to 1 millisecond. Electrophysiological recordings demonstrated that the trigger hairs function as mechanoreceptors. Associated with each trigger hair are large sensory cells, the sensory axons of which measure 15 to 20 micrometers in diameter. These are among the largest sensory neurons, and their size implies that these axons conduct information very rapidly. 相似文献

On 27 German Landrace boars studies were conducted to describe the effect of feeding level during the growth period on the microscopic picture of vesicular glands in boars at 5, 6 and 7 months of age. Investigations have shown that differentiation of feeding level during the growth period affected the development of internal structures of the parenchyma in the boars' vesicular glands. The size of the tubules, their number within the field of vision and height of glandular epithelium lining the tubules were the highest in the group of animals fed at increased level. 相似文献

Epidemiological observations on the course and spread of equine influenza in Poland during the 1969 epizootic were carried out. The dynamics of the spread of the disease in the country are shown graphically by voivodship. The disease incidence and mortality rates for the entire country are also shown. The highest incidence of disease and mortality rates were found to be in November 1969. A/equi-2/Warsaw/69 was identified as the causal virus. It caused the largest epizootic in the country since 1954. 相似文献
