FIG. 303. NERVE-CELLS OF HIRUDO (SCHAFER, AFTER APATHY). 



A, unipolar motor cell ; a, network of neuro-fibrils near the surface of the 

 cell ; b, near the nucleus n ; c, afferent ; d, efferent neuro-fibril. B, bipolar sensory 

 cell a with its nucleus n ; cu, cuticle ; ep, epidermis cells between which a neuro- 

 fibril passes up from its branched ending near the surface of the skin to the 

 nerve-cell, where it forms a network, which gives off a fibril passing towards the 

 central nervous system.
