testes cooler than the body temperature

• Made up of involuntary muscle fibers as part of the skin that make the scrotum draw up when chilled and hang down when heated

2.Neck

3.Connecting piece

4.Tail

• When the sperm penetrates an ovum during fertilization the tail separates from the rest of the sperm, the head and the connecting piece enter the ovum and the zygote is formed
