Cellular Structure

Question 1 - Single Best Answer

Identify the structure at the tip of the arrows:

E) stereocilia

Sorry...
Stereocilia are very long microvilli. When observed under a light microscope, they give the appearance of paint brush hairs due to their sticking together during the histochemical preparatory technique. They are only located on the epithelium from the inner ear (i.e., sensory hair cells) and the male reproductive tract (i.e., ductus epididymis).
