Cerebellar Diseases definition: Diseases that affect the structure or function of the cerebellum. Cardinal manifestations of cerebellar dysfunction include dysmetria, GAIT ATAXIA, and MUSCLE HYPOTONIA.
cerebellar disorder definition: condition in which there is a deviation from or interruption of the normal structure or function of the cerebellum; manifestations of cerebellar dysfunction include dysmetria, gait ataxia, and muscle hypotonia.
Cerebellar Neoplasms definition: Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs. (From Okazaki & Scheithauer, Atlas of Neuropathology, 1988, p86 and p141)
Cerebellar Neoplasm definition: A benign or malignant (primary or metastatic) tumor involving the cerebellum. -- 2003
Cerebellar Nuclei definition: Four accumulations of gray substance embedded in the white substance of the cerebellum, comprising the nucleus dentatus, nucleus emboliformis, nucleus globosus, and nucleus fastigii. (Dorland, 28th ed)
cerebellar nuclei definition: four accumulations of gray substance embedded in the white substance of the cerebellum from which most of the efferent fibers of the cerebellum arise; comprised of the nucleus dentatus, nucleus emboliformis, nucleus globosus, and nucleus fastigii.
Cerebellum definition: The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.
cerebellum definition: part of the metencephalon that lies in the posterior cranial fossa behind the brain stem; it is involved in the coordination of movement.
cerebellum definition: (sair-uh-BELL-um) The portion of the brain in the back of the head between the cerebrum and the brain stem. The cerebellum controls balance for walking and standing, and other complex motor functions.
Cerebellum definition: Organ component of neuraxis that has as its parts the cerebellar cortex, cerebellar nuclear complex and cerebellar white matter. Examples: There is only one cerebellum.
Malignant Cerebellar Neoplasm definition: Primary and secondary (metastatic) malignant tumors that occur in the cerebellum. Histologic types include medulloblastomas, high grade (WHO Stage III or IV) cerebellar astrocytomas, lymphomas, gangliogliomas, gliosarcomas, and several other subtypes. The most frequent malignant cerebellar neoplasm of childhood is medulloblastoma. In adults, metastases from other sites are relatively common. Clinical features include ataxia, headache, nausea, dizzyness, nystagmus, diplopia, papilledema, etc.
Childhood Cerebellar Astrocytoma definition: Benign and malignant astrocytomas that arise from astrocytes in the cerebellum. More than 80% of childhood cerebellar astrocytomas are pilocytic astrocytomas which have a favorable prognosis. The remainder are composed of diffuse or fibrillary subtypes with malignant astrocytomas occuring only rarely in the cerebellum during childhood.
Dysplastic Cerebellar Gangliocytoma definition: A benign, WHO grade I cerebellar mass, which occurs in young adults and is composed of dysplastic ganglion cells. It is the major CNS manifestation of Cowden Disease, an autosomal dominant condition that causes a variety of hamartomas and neoplasms.
Cerebellar Astrocytoma definition: Benign and malignant neoplasms of the cerebellum that arise from astrocytes. During childhood the majority are benign pilocytic astrocytomas. In adults both benign and relatively higher grade forms may occur. The most common presenting symptoms are headache, nausea, vomiting, ataxia of gait or limb, paresis, diplopia, and dizziness. Objective signs include weakness, long tract signs, dysmetria, gait ataxia, papilledema, and nystagmus. Surgical resection is often curative.
Benign Cerebellar Neoplasm definition: Non-malignant neoplasms that arise from cerebellar tissue. During childhood the most common form is pilocytic astrocytoma although fibrillary astrocytomas may also occur. These tumors may present with slowly progressive signs caused by a slowly expanding mass lesion or acutely due to hemorrhage of a vascular tumor. Clinical signs and symptoms may include ataxia, nystagmus, spasticity long tract signs, headache, nausea, vomiting, papilledema, diplopia, spasticity, and weakness, etc.)
Cerebellar Capillary Hemangioblastoma definition: A histologically benign tumor, usually cystic with a vascular mural nodule, that is most often found in the cerebellum though it has been reported at other sites within the neuraxis. It is associated with von Hippel-Lindau disease (VHL gene located on chr 3p25-26).
Cortical Cell Layer of the Cerebellum definition: The cortical cell layer of the cerebellum. It consists of the granular layer, molecular layer, and Purkinje cell layer.
cerebellum development definition: The process whose specific outcome is the progression of the cerebellum over time, from its formation to the mature structure. The cerebellum is the portion of the brain in the back of the head between the cerebrum and the pons. In mice, the cerebellum controls balance for walking and standing, modulates the force and range of movement and is involved in the learning of motor skills.

cerebellum morphogenesis definition: The process by which the anatomical structure of the cerebellum is generated and organized. Morphogenesis pertains to the creation of form. The cerebellum is the portion of the brain in the back of the head between the cerebrum and the pons. The cerebellum controls balance for walking and standing, modulates the force and range of movement and is involved in the learning of motor skills. [GO_REF:0000021, GOC:cls, GOC:dgh, GOC:dph, GOC:jic, GOC:mtg_15jun06, ISBN:0838580343]
cerebellum formation definition: The process that gives rise to the cerebellum. This process pertains to the initial formation of a structure from unspecified parts. The cerebellum is the portion of the brain in the back of the head between the cerebrum and the pons. The cerebellum controls balance for walking and standing, modulates the force and range of movement and is involved in the learning of motor skills. [GO_REF:0000021, GOC:cls, GOC:dgh, GOC:dph, GOC:jic, GOC:mtg_15jun06, ISBN:0838580343]
cerebellum structural organization definition: The process that contributes to the act of creating the structural organization of the cerebellum. This process pertains to the physical shaping of a rudimentary structure. The cerebellum is the portion of the brain in the back of the head between the cerebrum and the pons. The cerebellum controls balance for walking and standing, modulates the force and range of movement and is involved in the learning of motor skills. [GO_REF:0000021, GOC:cls, GOC:dgh, GOC:dph, GOC:jic, GOC:mtg_15jun06, ISBN:0838580343]
cerebellum maturation definition: A developmental process, independent of morphogenetic (shape) change, that is required for the cerebellum to attain its fully functional state. The cerebellum is the portion of the brain in the back of the head between the cerebrum and the pons. The cerebellum controls balance for walking and standing, modulates the force and range of movement and is involved in the learning of motor skills. [GO_REF:0000021, GOC:cls, GOC:dgh, GOC:dph, GOC:jic, GOC:mtg_15jun06, ISBN:0838580343]
