Morphology
Given the definitions of 'pterygoid' (relating to the wing-shaped processes of the sphenoid) and 'plexus' (an interconnected network of vessels or nerves), the phrase directly denotes a network located in the pterygoid region; the meaning is compositionally derived from its parts. Though specialized medical terminology, the 'X + plexus' anatomical naming pattern is regular and cross-linguistically transparent, so a learner who knows both constituents can infer the MWE's meaning.
Etymology
Pterygoid plexus comes from the words pterygoid meaning 'wing' and plexus meaning 'braid' or 'network'. Imagine a small braided net of veins near the jaw like a little wing, and that image explains why the term means the network of veins that collects blood from the jaw and mouth.
