| colliculectomy | Excision of the colliculus seminalis. (05 Mar 2000) |
|---|---|
| colliculitis | Inflammation of the urethra in the region of the colliculus seminalis. Synonym: verumontanitis. (05 Mar 2000) |
| colliculus | A small elevation above the surrounding parts. Origin: L. Mound, dim. Of collis, hill (05 Mar 2000) |
| colliculus cartilaginis arytenoideae | The elevation on the anterolateral surface of the arytenoid cartilage above the triangular fovea. Synonym: colliculus cartilaginis arytenoideae. (05 Mar 2000) |
| colliculus facialis | 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) |
| colliculus inferior | 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) |
| colliculus of arytenoid cartilage | The elevation on the anterolateral surface of the arytenoid cartilage above the triangular fovea. Synonym: colliculus cartilaginis arytenoideae. (05 Mar 2000) |
| colliculus seminalis | 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) |
| colliculus superior | 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) |
| colliculus urethralis | 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) |
| collier's lung | Pneumonoconiosis from accumulation of carbon from inhaled smoke or coal dust in the lungs. See: pneumomelanosis. Synonym: collier's lung, melanedema, miner's lung. Origin: anthraco-+ G. -osis, condition (05 Mar 2000) |
| Collier's sign | <clinical sign> Unilateral or bilateral lid retraction due to midbrain lesion; occurring at any age. See: setting sun sign, Epstein's sign. Synonym: Collier's tucked lid sign. (05 Mar 2000) |
| Collier's tract | A longitudinal bundle of fibres extending from the upper border of the mesencephalon into the cervical segments of the spinal cord, located close to the midline and ventral to the central gray matter; it is composed largely of fibres from the vestibular nuclei ascending to the motor neurons innervating the external eye muscles (abducens, trochlear, and oculomotor nuclei), and descending to spinal cord segments innervating the musculature of the neck. Synonym: fasciculus longitudinalis medialis, Collier's tract, medial longitudinal bundle, posterior longitudinal bundle. (05 Mar 2000) |
| Collier's tucked lid sign | <clinical sign> Unilateral or bilateral lid retraction due to midbrain lesion; occurring at any age. See: setting sun sign, Epstein's sign. Synonym: Collier's tucked lid sign. (05 Mar 2000) |
| Collier, James | <person> English physician, 1870-1935. See: Collier's tract, Collier's sign. (05 Mar 2000) |
