Flagella are long cellular projections that provide motility of cells. Unlike cilia, which are short and numerus, human flagellas are single long projections that extend in 1 direction.
On this page are photos of human sperm cells that I took with the microscope camera from our slide collection in either 2024 or 2009. Sperm cells have a head, that is really just a nucleus and a structure called an acrosome that has digestive enzymes, a midpeice, that contains mitochondria, and a single long flagella. And before you ask, we got the slide from Wards Scientific and I do not want to know where they got the sperm from.
