Morphology
The words 'motor' + 'system' transparently indicate a bodily system controlling movement, so a B1 learner would grasp it refers to a movement-related system. However, 'pyramidal' is a technical anatomical qualifier whose specific reference (the corticospinal/pyramidal tracts from cortex to spinal cord) requires specialist knowledge, so the full technical meaning is not predictable from the constituents alone.
Etymology
The term pyramidal motor system gets its name from the bundles of nerve fibers that look like small pyramids in the lower brain and run down to the spinal cord. Those bundles control 'voluntary muscle movement', so the name now refers to the brain system that makes movements on purpose.
