Horripilation
Definition:
(n.) A real or fancied bristling of the hair of the head or body, resulting from disease, terror, chilliness, etc.
Example Sentences:

(5) Horripilation was episodic in both men and women but related significantly to torso skin temperature in men and percent body fat in women over the range of torso skin temperatures tested.
(6) Additional observations include pronounced polydipsia, ascites, abdominal and subdural hemorrhage, and horripilation (piloerection) in experimental groups.
Piloerection
Definition:
Example Sentences:
