Describing something that is shaped like a funnel or related to a funnel-like structure.
The infundibular shape of the structure allows for efficient fluid flow.
Infundibular is formed from "in-" (meaning into) and "fundibulum" (from Latin, meaning funnel). The term describes something that is funnel-shaped or related to a funnel, indicating a structure that directs or channels something into a specific area.
Think of a funnel that directs things 'into' ('in-') a specific place, which helps you remember that 'infundibular' refers to something that is funnel-shaped.
