Morphology

plexus + brachialis

The term is compositionally built from 'plexus' (a network of nerves/vessels) plus an adjectival element related to 'brachial' (the arm), so the meaning ‘network of arm nerves’ is derivable from the parts. However, the Latinized, technical form 'brachialis' and the specialized medical register make it less immediately transparent to an average B1 learner, so full predictability is limited.

Etymology

Plexus brachialis comes from Latin words plexus ('braid') and brachialis ('arm'). The name gives the picture of many nerves woven together like a braid near the shoulder, so it means 'a network of nerves that sends signals to the shoulder, arm, and hand'.
