Mammillary Body - English Definition & Meaning

Definition

The mammillary body (or mamillary body) is a small, round structure in the brain. It's part of the limbic system, which is vital for memory and emotion. Think of them like relay stations 🚦, forwarding signals from the amygdala and hippocampus. They help consolidate memories, especially those linked to smell. The mammillary bodies receive signals and send them on to the thalamus. If damaged, it can lead to memory problems, like not remembering recent events. Overall, they're small but crucial for forming and recalling memories.

Etymology

The term 'mammillary' comes from the Latin word 'mamilla,' which means 'little breast' or 'nipple'. This refers to the shape of these structures, which resemble small, rounded bumps. The bodies were named for their appearance, not their function. 'Mamilla' is a diminutive of 'mamma,' meaning 'breast.' So, literally, it means 'little breast-shaped thing'.
