| granular layer of cerebellum | The deepest of the three layers of the cortex; it contains large numbers of granule cells, the dendrites of which synapse with incoming mossy fibres in cerebellar glomeruli. Thin, unmyelinated axons of granule cells ascend perpendicularly into the molecular layer in which they bifurcate into fibres coursing parallel to the long axis of the cerebellar folia. Parallel fibres form numerous synapses with the dendrites of Purkinje cells, basket cells, and stellate cells. Synonym: stratum granulosum cerebelli, granular layer of cerebellar cortex.

| molecular layer of cerebellum | The outer lamina of the cortex, containing the cell bodies and dendrites of Purkinje cells, the axons of the granule cells, and the cell bodies, dendrites, and axons of basket cells. Synonym: stratum moleculare cerebelli, molecular layer of cerebellar cortex. (05 Mar 2000) |
| crescentic lobules of the cerebellum | Archaic term designation for lobulus semilunaris inferior and lobulus semilunaris superior. (05 Mar 2000) |
| posterior notch of cerebellum | A narrow notch between the cerebellar hemispheres posteriorly, occupied by the falx cerebelli. Synonym: incisura cerebelli posterior, marsupial notch, posterior notch of cerebellum. (05 Mar 2000) |
| primary fissure of cerebellum | The deepest fissure of the cerebellum; demarcates the division of anterior and posterior lobes of the cerebellum; second to appear embryologically. Synonym: fissura prima cerebelli. (05 Mar 2000) |
| secondary fissure of cerebellum | A fissure that separates the uvula of the inferior vermis of the cerebellum from the pyramid. Synonym: fissura secunda cerebelli. (05 Mar 2000) |
| horizontal fissure of cerebellum | Horizontal fissure that divides the ansiform lobule into its major parts, crus I (superior semilunar lobule) and crus II (inferior semilunar lobule). Synonym: fissura horizontalis cerebelli, great horizontal fissure. (05 Mar 2000) |
| dentate nucleus of cerebellum | The most lateral and largest of the cerebellar nuclei; it receives the axons of the Purkinje cells of the neocerebellum (lateral areas of cerebellar cortex); together with the more medially located globosus and emboliform nuclei it is the major source of fibres composing the massive superior cerebellar peduncle or brachium conjunctivum. Synonym: nucleus dentatus cerebelli, corpus dentatum, dentatum. (05 Mar 2000) |
| tongue of cerebellum | A tongue-shaped sequence of flattened cerebellar folia forming the anterior (or superior) extreme of the cerebellar vermis, extending forward on the surface of the superior medullary velum between the two emerging superior cerebellar peduncles. Synonym: lingula cerebelli, lingua cerebelli, tongue of cerebellum. (05 Mar 2000) |
| transverse fissure of cerebellum | The cleft caused by the protrusion of the anterior lobe of the cerebellum over the superior and middle cerebellar peduncles. Synonym: fissura transversa cerebelli. (05 Mar 2000) |
| lingula of cerebellum | A tongue-shaped sequence of flattened cerebellar folia forming the anterior (or superior) extreme of the cerebellar vermis, extending forward on the surface of the superior medullary velum between the two emerging superior cerebellar peduncles. Synonym: lingula cerebelli, lingua cerebelli, tongue of cerebellum. (05 Mar 2000) |
| anterior white commissure | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies.

| Bouffardi's white mycetoma | <dermatology> A form of mycetoma common in India and found occasionally in Somalia, caused by the organism Streptomyces somaliensis; in this variety, the muscles, tendons, and bones of the foot are destroyed by the disease process; numerous draining sinuses discharge yellowish grains, clustered like fish roe. (05 Mar 2000) |
| Brumpt's white mycetoma | Mycetoma caused by Pseudallescheria boydii, occurring in temperate and subtropical areas in India; small, white to yellow, hard to soft granules are discharged through the draining sinuses. (05 Mar 2000) |
