| corpus quadrigeminum anterius | 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) |
| corpus quadrigeminum posterius | 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) |

| corpus restiforme | A lateral (larger) subdivision of the inferior cerebellar peduncle composed of a variety of fibres including, but not limited to, olivo-, reticulo-, cuneo-, trigemino-, and dorsal spinocerebellar. See: inferior cerebellar peduncle. Synonym: corpus restiforme. (05 Mar 2000) |
| corpus spongiosum penis | The median column of erectile tissue located between and ventral to the two corpora cavernosa penis; posteriorly it expands into the bulbus penis and anteriorly it terminates as the enlarged glans penis; it is traversed by the urethra. Synonym: corpus cavernosum urethrae, spongy body of penis. Corpus spongiosum urethrae muliebris, the submucous coat of the female urethra, containing a venous network that insinuates itself between the muscular layers, giving to them an erectile nature.
