QUÉ SIGNIFICA FOVEA CENTRALIS EN INGLÉS
Fovea centralis
La fovea centralis, también conocida como fóvea, es una parte del ojo, situada en el centro de la región macular de la retina. La fóvea es responsable de la visión central aguda, que es necesaria en los seres humanos para las actividades donde el detalle visual es de importancia primordial, como la lectura y la conducción. La fóvea está rodeada por el cinturón parafovea, y la región perifovea externa. La parafovea es la cinta intermedia, donde la capa de células ganglionares está compuesta de más de cinco filas de células, así como la densidad más alta de conos; La perifovea es la región más externa donde la capa de células ganglionares contiene dos a cuatro filas de células, y es donde la agudeza visual está por debajo del óptimo. La perifovea contiene una densidad aún más disminuida de conos, teniendo 12 por 100 micrómetros frente a 50 por 100 micrómetros en la fóvea más central. Esto, a su vez, está rodeado por un área periférica más grande que proporciona información altamente comprimida de baja resolución. Aproximadamente la mitad de las fibras nerviosas del nervio óptico llevan información de la fóvea, mientras que la mitad restante lleva información del resto de la retina. La parafovea se extiende hasta un radio de 1.
definición de fovea centralis en el diccionario inglés
La definición de fovea centralis en el diccionario es una pequeña depresión en el centro de la retina que contiene solo células cónicas y, por lo tanto, es el área de visión más nítida.
