For these reasons, most glassware is made from a borosilicate glass, such as Pyrex or Kimax. Some glassware isn't glass at all, but inert plastic such as Teflon. Each piece of glassware has a name and purpose. Use this photo gallery to learn the names and uses of different types of chemistry laboratory glassware.
The epididymis is a firm tube that lies on the back surface of each testicle. It is coiled in order to fit a length of nearly 20 feet into a small space. This long length acts as a storage space for the sperm and gives sperm time to mature.
A special feature of the lining of the epididymis is the presence of stereocilia â long, branching microvilli that increase the surface area of the lining cells. Stereocilia help the lining of the epididymis to absorb excess fluids from the hollow lumen of the epididymis, along with dead or defective sperm.
