Seminiferous Tubules. i. Each lobule contains one to four highly coiled tubules that course posteriorly and unite to form a complex network of channels called the rete testis ii.ined with a specialized stratified epithelium that includes the spermatogenic cells that give rise to sperm cells seminiferous tubules that produce and secrete male sex hormones iii. Interstitial cells (cells of Leydig)- specialized cells in the space between.
A: The difference is in the type of chemicals used. In lye relaxers, the active ingredient is sodium hydroxide. In no-lye relaxers, the active ingredient is calcium hydroxide. No-lye relaxer is usually a little milder and good for sensitive scalps, but the calcium can cause hair to be slightly drier. Most relaxer kits made for home use are no-lye formulas.
Eaton Y (Wye) strainers are a cost-effective solution for the mechanical removal of unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. They are used in pipelines to protect pumps, meters, control valves, steam traps, regulators and other process equipment. Y-Strainers (Wye-strainers) are typically used in applications where the amount of solids to be removed is small, and where frequent clean-out is not required. They are most often installed in gaseous services such as steam, air, nitrogen, natural gas, etc.
