Figure 5 Histology of the male reproductive tract of T. collaris. (A) Cross section of the confluence region of spermatic ducts and glands showing the presence of secretion (arrowhead) and spermatozoa (asterisk). (B) Cross and (C) longitudinal sections of the ejaculatory duct, indicating the cuboidal epithelium with basal nuclei (arrowhead), cuticle (arrowhead), and thick muscle layer (a = circular muscles, b = longitudinal muscles).

Figure 4 Histology of the male reproductive tract of T. collaris. (A and B) Longitudinal section of the glandular region showing a tubular gland (ag1) with lumen full of secretion (black asterisk). The arrowhead points to the nucleus of the epithelium, and the black arrows to the opening of the common duct into the bean-shaped gland (ag2) in a region that precedes the ejaculatory duct (ej). Note the multilobed secretion (white arrow), lumen with secretion (white asterisk), and muscle layer (m) of the bean-shaped gland (ag2). (C) Cross section of the apical portion of the tubular gland showing apocrine secretion (dashed circle) and secretion granules in the lumen (asterisk). Longitudinal section of the ejaculatory duct (ej) showing the lumen (asterisk), simple cuboidal epithelium (arrow), and thick muscle layer (m). Bars: A = 200 µm, B = 150 µm, and C = 100 µm.
