Morphology

posterior + cerebral + artery

Each constituent ('posterior' = at the rear, 'cerebral' = relating to the brain, 'artery' = a blood vessel) composes straightforwardly into a literal meaning: a blood vessel located at the back of the brain. The phrase follows standard English noun-modifier composition and the overall sense is directly inferable by a B1 learner who knows the component words, so it is transparently compositional.

Etymology

Posterior cerebral artery is a simple picture: posterior means 'back', cerebral means 'of the brain', and artery means 'blood vessel'. So it is the vessel that carries blood to the back part of the brain, which is why problems there can cause vision problems.
