| olivocerebellar tract | A large group of loosely arranged fibre fascicles emerging from the hilus of the olivary nucleus, crossing to the opposite side of the medulla oblongata through the stratum interolivare lemnisci and the contralateral olive, and joining the restiform body, the larger part of the contralateral inferior cerebellar peduncle; its fibres terminate in all parts of the cerebellar cortex as climbing fibres. Synonym: tractus olivocerebellaris. (05 Mar 2000) |
| olivocochlear | See: olivocochlear bundle. (05 Mar 2000) |
| olivocochlear bundle | A bundle of fibres that originates from the periolivary nuclei bilaterally, exits the brainstem on the vestibular nerve, joins the cochlear nerve in the inner ear, and terminates on outer hair cells. Synonym: bundle of Rasmussen, olivocochlear fibres. (05 Mar 2000) |
| olivocochlear fibres | A bundle of fibres that originates from the periolivary nuclei bilaterally, exits the brainstem on the vestibular nerve, joins the cochlear nerve in the inner ear, and terminates on outer hair cells. Synonym: bundle of Rasmussen, olivocochlear fibres. (05 Mar 2000) |

| olivomycins | <chemical> A mixture of several closely related glycosidic antibiotics obtained from actinomyces (or streptomyces) olivoreticuli. They are used as fluorescent dyes that bind to DNA and prevent both RNA and protein synthesis and are also used as antineoplastic agent. Pharmacological action: antibiotics, antineoplastic, fluorescent dyes, protein synthesis inhibitor. (12 Dec 1998) |

| olivopontocerebellar atrophy | A collection of diseases with atrophy of the cerebellum, pons, and inferior olives described in 1900 by dejerine and thomas. Signs and symptoms include ataxia of trunk and limbs, dysarthria, intention tremor, followed by generalised rigidity and dementia. (12 Dec 1998) |
| olivopontocerebellar degeneration | <neurology> An inherited disease especially. Of mid to late life that is characterised by ataxia, hypotonia, dysarthria, and degeneration of the cerebellar cortex, middle cerebellar peduncles, and inferior olives. (09 Oct 1997) |
| olivospinal tract | A slender bundle of nerve fibres in the peripheral zone of the lateral funiculus of the spinal cord, composed of spino-olivary fibres more likely than olivospinal fibres. Synonym: Helweg's bundle. (05 Mar 2000) |
