ABSTRACT

Histológicamente la corteza del cerebelo humano adulto presenta tres capas constitutivas; la capa molecular, la hilera de los cuerpos de las células de Purkinje y la capa granulosa interna. La sustancia cortical del cerebelo de los embriones de mamífero, así como la de los jóvenes, muestran una capa granular externa. Nuestro objetivo es documentar las diferencias morfológicas entre las capas de la corteza cerebelosa adulta y joven. Se realizaron estudios morfométricos microscópicos en 20 cerebelos de autopsias. Los casos se dividieron en dos grupos, adultos y niños menores de 1 año. Se realizaron cortes en parafina, coloreados con hematoxilina y eosina. La corteza del cerebelo adulto presentó diferencias morfológicas con la de los recién nacidos. En el cerebelo adulto presenta tres capas constitutivas, mientras que en el recién nacido presenta una cuarta capa, la granulosa externa...


Histologically, the adult human cerebellar cortex has three constituent layers, the molecular layer, the row of bodies of Purkinje cells and internal granular layer. The cortex of the cerebellum of mammalian embryos, as well as youth, show external granular layer. Our goal is to document morphological differences between the layers of the cerebellar cortex adult and young. Microscopic morphometric studies were performed in 20 cerebellum autopsied. The cases were divided into two groups, adults and children under 1 year. Paraffin sections were performed, stained with hematoxylin and eosin. The cortex of adult cerebellum showed morphological differences of the newborn. In the adult cerebellum has three constituent layers, whereas in the newborn has a fourth layer, the external granular...
