Root Explanation

Choroid is formed from "choroides" (from Greek, meaning resembling the chorion, which is the outer membrane of an embryo) and "-oid" (meaning like or resembling). The word "choroid" refers to a structure that resembles the chorion, specifically the vascular layer of the eye between the retina and the sclera.

Memory Tip

Think of the Greek word for the outer membrane ('choroides') to remember that 'choroid' refers to a layer in the eye that resembles this outer structure.
