Corona radiata (embryology) - Wikipedia
The corona radiata is formed when the granulosa cells enlarge and become cuboidal, which occurs during the transition from the primordial to primary stage. These cuboidal granulosa cells, also known as the granulosa radiata, form more layers throughout the maturation process, and remain attached to the zona pellucida after the ovulation of the ...
Ovary Development - Embryology
6 天之前 · The corona radiata are the granulosa cells that directly surround the oocyte, and are released along with it at ovulation. Following ovulation, the corona radiata provide physical protection to the oocyte and are the initial structural barrier that spermatazoa must penetrate during fertilization.

The corona radiata is an outer layer of follicular (granulosa) cells that form around a developing oocyte in the ovary and remain with it upon ovulation. The underlying zona pellucida (pellucid = “transparent”) is a transparent, but thick, glycoprotein membrane that …

3 天之前 · The corona radiata are the granulosa cells that directly surround the oocyte, and are released along with it at ovulation. Following ovulation the corona radiata provide physical protection to the oocyte and granulosa cells within the ovulating follicle contribute to …
Corona Radiata - an overview | ScienceDirect Topics
The corona radiata refers to a highly cellular layer surrounding the egg in the ampullary part of the uterine tube. It consists of proteins and a high concentration of carbohydrates, including hyaluronic acid.

2023年7月26日 · The enzymes scatter the corona radiata (follicular cells) that surrounds the secondary oocyte, thus allowing the sperm to propel forward.
Corona radiata - Wikipedia
In neuroanatomy, the corona radiata is a white matter sheet that continues inferiorly as the internal capsule and superiorly as the centrum semiovale. This sheet of both ascending and descending axons carries most of the neural traffic from and to the cerebral cortex.
Fertilization - Embryology
1 天前 · Fertilization is the fusion of haploid gametes, egg and sperm, to form the diploid zygote. Note though there can be subtle differences in the fertilization process which occurs naturally within the body or through reproductive technologies outside the body, the overall product in both cases is a diplod zygote.

2023年4月17日 · The three barriers around the secondary oocyte are the corona radiata, zona pellucida, and vitelline membrane. Nevertheless, before the actual fertilization (penetration) occurs, the spermatozoa must undergo a process called capacitation, followed by an acrosomal reaction (discussed in the Cellular Section). These two processes help a sperm ...
