The term "zona radiata" refers to a layer of cells surrounding the mammalian oocyte. The spelling of this word can be explained through the use of IPA phonetic transcription. The first part of the word, "zona", is pronounced /ˈzoʊnə/. The second part, "radiata", is pronounced /ˌreɪdiˈeɪtə/. The stress in the pronunciation falls on the second syllable of "radiata".

ZONA RADIATA Meaning and Definition

1. Zona radiata, also known as the radiate zone, refers to a specific layer or region found within the embryonic form known as the oocyte, which is the female gametocyte or egg cell. This zone is a crucial part of the formation of the egg in most animals and contains various components that play significant roles in the process of fertilization and early embryonic development.

   The zona radiata is primarily composed of a specialized extracellular matrix known as the zona pellucida. This matrix is a glycoprotein-rich structure that surrounds the oocyte and acts as a protective barrier. It plays an essential role in mediating the processes of sperm binding, fertilization, and preventing polyspermy (i.e., the entry of multiple sperms into the egg).

   In addition to the zona pellucida, the zona radiata also contains other important components such as the cortical granules, which are secretory vesicles found in the outer oocyte membrane. These granules are involved in different cellular events after fertilization, including the block of polyspermy and the initiation of the early stages of embryo development.

   Overall, the zona radiata is a key part of the egg structure that provides protective and functional support for fertilization and early embryonic development.

2. The faintly striated investment of the oocyte; z. pellucida.
