Which term is defined as a large blister?

Explanation:
In dermatology, a large blister is called a bulla. This term is used when a fluid-filled lesion is bigger than a vesicle, which is defined as less than 1 centimeter in diameter; once the lesion exceeds that size, it’s termed a bulla. The plural is bullae. The other options refer to conditions or structures outside of this skin-lesion terminology: catatonia is a motor/behavioral syndrome, dementia is a progressive cognitive disorder, and the coronal plane is an anatomical boundary that divides the body into front and back portions.
