Ibacus leg motor neurons Figure 4.png

Distal leg motor neurons of slipper lobsters, <em>Ibacus</em> spp. (Decapoda: Scyllaridae) N1 fills proximal to the branch point of AV and PV. <strong>A.</strong> Photograph of intensified <em>Ibacus peronii</em> T4 backfill of N1, showing two medial cell bodies and two processes crossing into the contralateral hemiganglion. <strong>B.</strong> Camera lucida drawing of <em>I. alticrenatus</em> backfill of N1 in ganglion T4 showing medial cell with process projecting into the contralateral hemiganglion.

拖鞋龙虾（扁足蝉虾属*Ibacus* spp.，十足目：蝉虾科）的远端腿部运动神经元，其N1位于AV与PV分支点的近端区域。**A.** 扁足蝉虾（*Ibacus peronii*）T4神经节中N1经逆行填充标记（backfill）后的增强照片，可见两个内侧神经元胞体以及两条投射至对侧半神经节的突起。**B.** 高脊扁足蝉虾（*I. alticrenatus*）T4神经节中N1经逆行填充标记后的投影描绘器（Camera lucida）绘图，显示内侧神经元的突起投射至对侧半神经节。
