| habenular commissure | The connection between the right and left habenular nuclei; the decussation of fibres of the two striae medullares, forming the dorsal portion of the peduncle of the pineal body. Synonym: commissure of habenulae, habenular commissure. (05 Mar 2000) |

| posterior labial commissure | A slight fold uniting the labia majora posteriorly in front of the anus. Synonym: commissura labiorum posterior. (05 Mar 2000) |
| hippocampal commissure | The triangular subcallosal plate of commissural fibres resulting from the converging of the right and left fornix bundles which exchange numerous fibres and which curve back in the contralateral fornix to end in the hippocampus of the opposite side. Synonym: commissura hippocampi, commissure of fornix, delta fornicis, hippocampal commissure, psalterium, transverse fornix. (05 Mar 2000) |
| seminal colliculus | An elevated portion of the urethral crest upon which open the two ejaculatory ducts and the prostatic utricle. Synonym: colliculus seminalis, caput gallinaginis, colliculus urethralis, seminal hillock, verumontanum. (05 Mar 2000) |
| nucleus of inferior colliculus | The nerve cell groups composing the colliculus inferior. Synonym: nucleus colliculi inferioris. (05 Mar 2000) |
| superficial gray layer of superior colliculus | See: gray layer of superior colliculus. (05 Mar 2000) |
| superior colliculus | The paired, larger, rounded anterior eminence of the laminae of mesencephalic tectum; major afferent connections of the superficial layers are the retina and striate cortex; input to deep layers of the colliculus are polymodal. Its efferent connections are with the lower brainstem and spinal cord (tectobulbar tract and tectospinal tract) and with the pulvinar and other cell groups in the caudal part of the thalamus; participates in extrageniculate visual pathway. Synonym: colliculus superior, anterior quadrigeminal body, corpus quadrigeminum anterius. (05 Mar 2000) |
| deep gray layer of superior colliculus | A layer of myelinated fibres, the deepest layer of the colliculus superior, delimiting the latter from the central gray substance surrounding the cerebral aqueduct. Synonym: stratum album profundum. (05 Mar 2000) |
| deep white layer of superior colliculus | See: gray layer of superior colliculus. (05 Mar 2000) |
| inferior colliculus | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway. Synonym: colliculus inferior, corpus quadrigeminum posterius, inferior nasal colliculus, posterior quadrigeminal body. (05 Mar 2000) |
| inferior nasal colliculus | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway. Synonym: colliculus inferior, corpus quadrigeminum posterius, inferior nasal colliculus, posterior quadrigeminal body. (05 Mar 2000) |
| facial colliculus | Prominent portion of the medial eminence, just rostral to the medullary striae in the rhomboidal fossa; it is formed by the internal genu of the facial nerve and the abducens nucleus around which the facial fibres curve. Synonym: colliculus facialis, abducens eminence, eminentia abducentis, eminentia facialis, facial eminence, facial hillock. (05 Mar 2000) |
| labial commissure | Junction of upper and lower lip which occurs at corner of mouth. See: angle of mouth. (05 Mar 2000) |
| lateral palpebral commissure | The union of the upper and lower eyelids adjacent to the lateral angle. Synonym: commissura palpebrarum lateralis. (05 Mar 2000) |
