Cercopithecus nictitans
Cercopithecus nictitans, the putty-nosed or greater spot-nosed monkey (Simia nictitans, Linnaeus 1766), is a large West and Central African guenon with a white nose spot; IUCN Near Threatened, declining from bushmeat hunting and deforestation.
Cercospora

Cerdocyon
Cerdocyon is a monotypic genus of South American canids whose only living species, the crab-eating fox (Cerdocyon thous), is an omnivorous fox ranging from Colombia and Venezuela to northern Argentina.
Cereal
Cereal: Poaceae grasses grown for edible starchy grain (wheat, maize, rice, barley, oats, rye, sorghum, millets), distinct from pseudocereals like buckwheat and quinoa; supply ~45% of global calories.
Cereal germ
Cereal germ is the vitamin-rich embryo of a grain kernel, separated during milling. Wheat germ holds 25% protein, 8-13% lipids, and vitamin E, but oxidizes rapidly without stabilization.
Cerebellar ataxia
Cerebellar ataxia is loss of coordination from cerebellar damage, spanning hereditary SCAs, Friedreich ataxia, sporadic SLOCA, MSA-C, and acquired causes; diagnosed by MRI, genetics, and SARA scale.
Cerebellar ataxia with neuropathy and bilateral vestibular areflexia syndrome
CANVAS (MIM 614575), cerebellar ataxia with neuropathy and bilateral vestibular areflexia, an adult-onset autosomal recessive disorder caused by biallelic AAGGG repeat expansions in RFC1, distinguished from MSA by vestibulopathy and chronic dry cough.
Cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss syndrome
CAPOS syndrome (cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss syndrome, OMIM 601338) is a rare ATP1A3 p.Glu818Lys disorder with fever-triggered ataxic episodes and progressive vision and hearing loss.
Cerebellar ataxia-hypogonadism syndrome
Cerebellar ataxia-hypogonadism syndrome, also called Gordon Holmes syndrome (ORPHA:1173, OMIM 212840), is a very rare autosomal recessive neurodegenerative disorder combining progressive cerebellar ataxia with hypogonadotropic hypogonadism, caused by RNF216, PNPLA6, or STUB1 mutations.
Cerebellar ataxia, Cayman type
Cerebellar ataxia, Cayman type (Cayman ataxia) is a rare autosomal recessive disorder first described on Grand Cayman Island, caused by mutations in the ATCAY gene.
Cerebellar Golgi cell
The cerebellar Golgi cell is a large GABAergic inhibitory interneuron of the cerebellar granular layer, first described by Camillo Golgi in 1873, that regulates granule cells.
Cerebellar haemorrhage
Cerebellar haemorrhage (cerebellar hemorrhage, ICD-11 8B00.3) is bleeding into the cerebellum, 9-10% of intracranial hemorrhages, with 30-50% 30-day mortality; key risks are hydrocephalus, hematoma over 3 cm, coagulopathy, and intraventricular extension.
Cerebellar hemorrhage
A cerebellar hemorrhage is bleeding into the cerebellum, accounting for 9% to 10% of intracranial hemorrhages, usually from hypertension, and often requiring surgery when it compresses the brainstem.
Cerebellar hypoplasia
Cerebellar hypoplasia (CH): a cerebellum of reduced volume with preserved shape, a non-specific neuroimaging finding. Causes span genetic syndromes (Joubert, CHARGE), chromosomal and metabolic disorders, prenatal infection, prematurity, and 11 types of pontocerebellar hypoplasia.
Cerebellar hypoplasia (non-human)
Cerebellar hypoplasia, known in cats as Wobbly Kitten Syndrome, is a congenital, nonprogressive condition where the cerebellum fails to develop before birth, causing tremors and ataxia; in kittens it usually follows in utero feline panleukopenia infection.
Cerebellar liponeurocytoma
Cerebellar liponeurocytoma (cLNC), formerly lipomatous medulloblastoma, is a rare WHO grade II cerebellar neuronal tumor of adults with neurocytic and lipidized cells, treated by resection, with 5-year survival about 92% but frequent recurrence.
