Morphology

preanal = anal (transparent) = pre + anal

This is standard prefixation: 'pre-' added to 'anal' gives the meaning 'in front of or before the anal region'.

Etymology

Preanal combines pre- meaning 'before' and anal from 'anus', the body's back opening, so preanal means the area just in front of the anus and is used in anatomy and biology.
