Morphology

brachialis = brachial (opaque) = brachial + is

The form clearly relates to 'brachial' (relating to the arm), but the added '-is' and the shift to a muscle name is specialized and not fully predictable for general learners.

Etymology

Brachialis comes from the Latin brachium, meaning 'arm', so the name literally means 'of the arm' and helps you remember this muscle sits in the upper arm and helps bend the elbow.
