Extending from the cerebral ganglion are the following 6 pairs of nerves: 2 pairs of anterior medial nerves, 2 pairs of lateral medial nerves, 1 pair of anterior proboscis nerves, 1 pair of lateral medial nerves. The dorsal anterior medial nerve and the ventral anterior medial nerve are unpaired nerves. The dorsal anterior medial nerve supplies the apical sensory device on the proboscis. The ventral anterior medial nerve supplies the retractor and protrusor muscles of the proboscis and the lateral posterior nerve supplies the longitudinal and circular muscles of the body wall. This last nerve is the largest of the nerves and is enclosed by the retinacular muscle as it extends through the pseudocoel to the body wall where it divides into a posterior and anterior nerve. The anterior medial nerve originates from 2 different levels along the dorsal anterior surface of the ganglion. These nerves serve the anterior presoma. The anterior proboscis nerve originates from the apical cells of the ganglion and is found between the proboscis retractor muscles throughout their length.
从脑神经节延伸出以下6对神经：2对前内侧神经、2对外侧内侧神经、1对吻前神经、1对外侧内侧神经。背侧前内侧神经和腹侧前内侧神经是不成对的神经。背侧前内侧神经为吻部顶端的感觉器提供神经支配。腹侧前内侧神经为吻部的收缩肌和伸展肌提供神经支配，外侧后神经为体壁的纵肌和环肌提供神经支配。最后这条神经是最大的神经，当它穿过假体腔延伸至体壁时被支持肌包围，在体壁处它分为一条后神经和一条前神经。前内侧神经沿神经节背侧前表面从2个不同水平发出。这些神经为身体前部提供神经支配。吻前神经起源于神经节的顶端细胞，在其全长都位于吻部收缩肌之间。
