means the same but differs only by phrasing of the name

Morphology

amyloid + plaque

The noun phrase is directly compositional: 'amyloid' names a specific protein and 'plaque' denotes a deposit, so 'amyloid plaque' literally means a deposit of amyloid protein. This transparent, non-idiomatic medical compound follows regular noun+noun composition and would be inferable by a B1 learner who knows both constituent words.

Etymology

Amyloid plaque comes from a simple image: sticky protein called amyloid gathers into a flat patch, a plaque, on the brain. That's why the name refers to those protein 'clumps' that build up and harm brain cells in Alzheimer's disease.
