| colliculitis | Inflammation of the urethra in the region of the colliculus seminalis. Synonym: verumontanitis. (05 Mar 2000) |
|---|
| brachium colliculi inferioris | A fibre bundle passing from the inferior colliculus on either side of the brainstem along the lateral border of the superior colliculus to the posterior part of the thalamus where it enters the medial geniculate body. It forms part of the major ascending auditory pathway. Synonym: brachium colliculi inferioris, brachium quadrigeminum inferius, inferior quadrigeminal brachium. (05 Mar 2000) |
|---|---|
| brachium colliculi superioris | A band of fibres of the optic tract bypassing the lateral geniculate body to terminate in the superior colliculus and pretectal region. Synonym: brachium colliculi superioris, brachium quadrigeminum superius, superior quadrigeminal brachium. (05 Mar 2000) |
| commissure of inferior colliculi | Nerve fibres on the midline between the two inferior colliculi connecting the colliculi and containing some fibres originating from nontectal nuclei. (05 Mar 2000) |
| stratum cinereum colliculi superioris | Term applied to any one of the three major layers of gray matter of the superior colliculus that alternate with layers composed chiefly of nerve fibres: 1) the superficial gray layer of superior colliculus, above the largely white layer of the incoming fibres of the optic tract (optic layer); 2) the middle gray layer of superior colliculus, placed between the optic layer and a more deeply located layer of fibres, the stratum lemnisci; 3) the deep gray layer of superior colliculus, between the stratum lemnisci and the central gray substance surrounding the cerebral aqueduct, and containing the large nerve cells from which most of the colliculus descending connections (tectobulbar, tectopontine, and tectospinal tract) originate. Synonym: stratum griseum colliculi superioris, stratum cinereum colliculi superioris. (05 Mar 2000) |
