摘要: The antennae of the sphinx moth Manduca sexta are multimodal sense organs, each comprising three segments: scape, pedicel, and flagellum. Each antenna is moved by two systems muscles, one controlling movement scape consisting five muscles situated in head capsule (extrinsic muscles), other system located within (intrinsic muscles) four that move pedicel. At least seven motoneurons innervate extrinsic at intrinsic muscles. dendritic fields antennal overlap another extensively neuropil mechanosensory motor center. density motoneuronal arborizations greatest lateral part this region decreases more medially. None exhibits a contralateral projection. cell bodies innervating distributed throughout an arching band neuronal somata dorsal dorsolateral to center, whereas reside mainly among neuropil.
