An explanation of the origin of the word "crests" in Act 5, Scene 7 of myShakespeare's Macbeth

Macbeth

As easy mayst thou the intrenchant air
With thy keen sword impress as make me bleed.
Let fall thy blade on vulnerable crests;
I bear a charmed life which must not yield
To one of woman born.

Video Transcript: 

RALPH: The word “Crest” derives from the latin word crista. In English, as well as in Latin, it refers to the tuft of feathers or hair on an animal’s head. 
DAVINA: Because these crests give the animal an appearance of pride and self-confidence, military figures used feathers as ornaments on their helmets. 
RALPH: Shakespeare is referring to that practice when he uses “crest” metaphorically to stand for the helmet itself.
