1. Located on the venter. For legs this means that these are considered as if they were in the position as given in the illustration. So, even if a leg is pointing upwards in a specimen, one should image that the leg was positioned in a horizontal plane, perpendicular to the body axis.
2. Located in a more position towards the venter. For example, a seta can be located ventral to another seta.
Fortunately the leg flexes (bends) in the dorsoventral plane so the legs dorsum and ventrum are easily identified. The periphery
(outside) of a transverse section is then divided into eight imaginary parts, which (looking down the leg towards the body read in the direction of a clock)
