QUE SIGNIFIE SEMINIFEROUS EN ANGLAIS
Tubule séminifère
Les tubules séminifères sont situés dans les testicules, et sont la localisation spécifique de la méiose et la création ultérieure de gamètes, à savoir les spermatozoïdes. L'épithélium du tube se compose de cellules sustentaculaires ou de Sertoli, qui sont des cellules de type grand et en forme de colonne qui bordent le tubule. Entre les cellules de Sertoli sont des cellules spermatogènes, qui se différencient par la méiose aux spermatozoïdes. Il existe deux types: enroulé et droit, enroulé vers le côté latéral, et droit lorsque le tubule vient en direction médiale pour former des conduits qui vont sortir du testicule. Les tubules séminifères sont formés à partir de cordes sexuelles primitives. Ce sont les cordes médullaires qui se développent dans les tubules séminifères et les cordes corticales régressent. Les cordes ont été formées à partir de la crête gonadique.
