... Wing beat frequency Muscle tension Muscle stiffness Small insects require high wing beat frequencies to generate sufficient aerodynamic power for flight. Many flight muscle adaptations have evolved to enable power generation at high muscle speeds. Some insect flight muscles are not directly...

... to >20°C, neurally evoked relaxations of resting muscle tension are effective only at colder temperatures at which the inhibitory junction potentials are hyperpolarizing in polarity. 5-HT has two effects on inhibitory synaptic signals: it potentiates their amplitude and also shifts the temperature...
