Morphology

callosal = callosum (semi-transparent) = callos + al

The adjective is a regular relational formation in -al from the specialized anatomical noun callosum, but the base is unlikely to be familiar to an average learner.

Etymology

Callosal comes from the Latin callosus, meaning 'hard' or 'thick', and shares the same root as English callus for hard skin. The brain part called the corpus callosum was named as a thick, tough band that joins the two halves of the brain, so callosal means 'relating to that connecting band'.
