Sperm cells have a head containing enzymes and a nucleus, and a long tail that provides movement to swim and find egg cells in the testes. Egg cells are large and bulky, found in ovaries, and contain yolk to provide nutrition for development after fertilization by sperm in the ovaries. Nerve cells are long with connections at each end to carry electrical signals between body parts.
