Straight tubules
Tubuli seminiferi recti
- Latin synonym: Tubuli recti testis
Definition
In the apices of the lobules, the tubules become less convoluted, assume a nearly straight course, and unite together to form from twenty to thirty larger ducts, of about 0.5 mm. in diameter, and these, from their straight course, are called tubuli recti.
The tubuli recti enter the fibrous tissue of the mediastinum, and pass upward and backward, forming, in their ascent, a close net-work of anastomosing tubes which are merely channels in the fibrous stroma, lined by flattened epithelium, and having no proper walls; this constitutes the rete testis.
The tubuli recti have very thin walls; like the channels of the rete testis they are lined by a single layer of flattened epithelium.
