The Physiology of a Lepidopteran Muscle Receptor

摘要: 1. When a single MRO of caterpillar is stretched at least 32 motor units show clear reflex changes in activity. 2. The great majority muscles are excited and the latency differs only slightly from one muscle to another. response has both tonic phasic components which reflect more or less faithfully magnitudes same sensory discharge. 3. Muscles affected on contralateral side stimulated segment ipsilateral adjacent segments. fields neighbouring receptors therefore overlap; spatial facilitation produces disproportionate increase overall when two simultaneously. 4. pathway for innervated by nerve 2 shown involve synaptic connexions ganglion anterior receptor responding muscles. 5. most strongly those lie functionally parallel with sense organ. It concluded that major function mediate negative feedback tending stabilize bodily position independent load.
