Mammillary Body
The Mammillary Body (pronunciation: mam-uh-luh-ree boh-dee) is a pair of small round bodies, located on the undersurface of the brain that form part of the limbic system. They are associated with memory and are named for their resemblance to breasts (mammillae).
Etymology
The term "Mammillary Body" is derived from the Latin word 'mammilla' meaning 'little breast', due to its shape. The term was first used in the 17th century.
Function
The Mammillary Bodies are important for recollective memory. They receive signals from the hippocampus via the fornix and project them to the thalamus, a part of the brain that is involved in consciousness, sleep, and sensory interpretation.
