commissure[′käm·ə‚shu̇r] (biology) A joint, seam, or closure line where two structures unite. Commissure in human and animal anatomy, a site of union or junction. The commisura labiorum oris is the junction of the lips at the corners of the mouth. The anterior commissure of the cerebrum is the transverse bundle of nerve fibers that unites the corpora striata of the forebrain in the majority of vertebrates. The anterior commissure of the mantle, or the commissura fornicis, joins the hemispheres of the forebrain in dipnoans and terrestrial vertebrates—the basis of the corpus callosum in mammals. commissureenUK
