The gonads, as in other Arthropoda, are hollow saccular organs, the cavity communicating with the efferent ducts.
Various accessory structures may be connected with the efferent ducts in both sexes.
The boy who had had to stay in a therapy chair all his life because his efferent nerves could not control his body.
This vesicle appears as a continuation of the Mllerian ducts, but receives a number of the efferent ductules of the kidneys.
But the efferent ductules from the kidney gradually alter their points of entrance into the primitive duct.
