Related to pinus: Pinus pinaster
a small, unpaired, flattened body, shaped somewhat like a pinecone, attached at its anterior pole to the region of the posterior and habenular commissures and lying in the depression between the two superior colliculi below the splenium of the corpus callosum; it is a glandular structure, composed of follicles containing epithelioid cells and lime concretions called brain sand; despite its attachment to the brain, it appears to receive nerve fibers exclusively from the peripheral autonomic nervous system. It produces melatonin and serotonin.
