Fig. 3. Photomicrograph of transverse section of tench spinal cord in tail region
( 10 p, silver stained). C, Central canal; Pm, primary motoneuron; and Ma, Mauthner
axon. Note: Ventral process from primary motoneuron on left, running down toward
dorsal collateral of left Mauthner axon; also large cells above right Mauthner axon:
the most dorsal one is a primary motoneuron, the other three are probably group B
motoneurons .
