Sperm cell anatomy. Cutaway computer artwork showing the internal structure of a sperm cell (spermatozoon), the male sex cell. Each sperm cell consists of a head (upper right), mid-piece (centre left) and tail (lower left). The head contains the acrosome, which will pierce the egg's membrane during fertilisation, and the nucleus, within which is the genetic material. The mid-piece contains the centriole and numerous mitochondria (disc-shaped) that provide the energy necessary for the cell to swim. The tail contains microtubules arranged in a central axial filament (axoneme) that spins in a twisting motion to propel the sperm towards the egg for fertilisation.
