Olivary body - Wikipedia, the free encyclopedia (630 words)
In anatomy, the olivary bodies or simply olives (Latin oliva and olivae, singular and plural, respectively) are a pair of prominent oval structures in the medulla oblongata, the lower portion of the brainstem.
The olivary body is located on the anterior surface of the medulla lateral to the pyramid, from which it is separated by the antero-lateral sulcus and the fibers of the hypoglossal nerve.
The superior olivary nucleus is considered part of the pons, and is therefore discussed in a separate article.
