Figure 2 Histology of the male reproductive tract of T. collaris. (A) Longitudinal section of a testis showing the follicles (f); growth (a), maturation (b), and differentiation (c) zones; and vas efferens (ve) opening (arrow) into a vas deferens (vd) with lumen full of spermatozoa (asterisk). (B) Longitudinal section showing detail of the vasa efferentia (ve) in the confluence zone (black arrow) with the vas deferens (vd). The white arrow points to sperm bundles in the vas efferens.
