ventral ganglion
(Order Decapoda):
One in a series of ganglion pairs of ventral nerve cord in thorax (thoracic ganglion) or abdomen (abdominal ganglion). Segmentally arranged, each giving rise to pair of nerves. Ganglion pairs may shift anteriorly and be fused with one another to form cephalothoracic ganglion [Stachowitsch, 1992].
