Ootid (Noun)
Meaning
Mature ovum after penetration by sperm but before the formation of a zygote.
Classification
Nouns denoting body parts.
Examples
- The ootid has a unique developmental potential that differs significantly from both the mature oocyte and the zygote.
- During this stage, the ootid undergoes a series of changes that prepare it for the fusion of the sperm and the egg.
- The transformation of the ootid to a zygote occurs after the fusion of the sperm and egg pronuclei.
- After the ootid has been fertilized, it enters the second meiotic division and expels the second polar body.
- In humans, the ootid is formed about 18-24 hours after ovulation, at which point it is released from the ovary and enters the fallopian tube.
