Morphology
corpus + callosum
This is a Latinized anatomical name: even if a learner knows 'corpus' as 'body', 'callosum' is not a transparent modern English word (and is not given in the dictionary here), so the specific sense 'broad band of nerve fibers joining the two hemispheres' cannot be derived from the parts. The meaning is a conventional technical label rather than a compositional phrase, so it would be unpredictable to a B1 learner.
Etymology
Corpus callosum comes from Latin words corpus meaning 'body' and callosum meaning 'hard' or 'thick'. The name gives a simple picture: a thick 'body' of nerve fibers that sits between the two sides of the brain and 'joins' them, so it refers to the band that connects left and right.
