This image illustrates the leg and muscles of the fruitfly. The spiky tissue is part of one of the fly's legs, while the blue and green striped tissues are muscles where the leg attaches to the insect's body. The red stain highlights the attachment of the bristles to the leg. Muscle development in the fly and in the human occurs via remarkably similar processes, using similar gene networks.
