Measures of Heart and Ventilatory Rates in Freely Moving Crayfish
The fear, flight or fight response serves as the fundamental physiological basis for examining an organism's awareness of its environment under an impending predator attack. Although it is not known whether invertebrates possess an autonomic nervous system identical to that of vertebrates, evidence shows invertebrates have a sympathetic-like response to regulate the internal environment and rea...
متن کاملHeart and ventilatory measures in crayfish during environmental disturbances and social interactions.
Most animals assess the environment in which they live and alter their behavior according to various stimuli. When the animal does not make significant behavioral changes, as measured by bodily movements, the animal may be characterized as unresponsive to a given stimulus. This study demonstrates that when behavioral movements of crayfish cannot be observed, physiological measures of heart rate...
متن کاملHeart rate measures in blind cave crayfish during environmental disturbances and social interactions.
Most animals continually assess the environment in which they live and alter their behavior according to various stimuli. As an observer, one looks for changes in a behavior indicating that an animal responded to a particular event. When the animal does not make significant behavioral changes as measured by bodily movements, the animal may be characterized as unresponsive to a given stimulus. T...
متن کاملVentilatory Abnormalities During Exercise in Heart Failure: A Mini Review
Heart Failure (HF) is a significant health care concern with in both the United States and Europe. While there are a number of mechanisms that lead to HF, a decline in the response to exercise is common amongst the various etiologies. Cardiopulmonary exercise testing (CPET) is a well established diagnostic and prognostic tool in the HF population. This exercise testing technique allows for the ...
متن کاملBioelectric field potentials of the ventilatory muscles in the crayfish.
This study investigated the pattern of the electrical field potentials recorded near the prebranchial chamber of the native crayfish Astacus leptodactylus. Inside the prebranchial chamber, the electrical waves had maximal amplitude and showed 2-4 peaks per cycle. Potentials with the same frequency but smaller amplitude and simpler shape were also recorded outside the chamber, near the edge of t...
