Related to Immature ovum: ootid, secondary oocyte

ootid

 [o´o-tid]
a mature oocyte (ovum); the cell produced by meiotic division of a secondary oocyte. In mammals, this second maturation division is not completed unless fertilization occurs.

o·o·tid

(ō'ō-tid),
The nearly mature oocyte after the first meiotic division has been completed and the second initiated; in most higher mammals, including humans, the second meiotic division is not completed unless fertilization occurs. Thereafter the ootid contains two separate haploid elements, the female and male pronuclei. When the pronuclei fuse, the ootid becomes a zygote.
[G. ōotidion, a diminutive egg. See -id (2)]

ootid

/oo·tid/ (-tid) a mature oocyte; one of four cells derived from the two consecutive divisions of the primary oocyte. In mammals, the second maturation division is not completed unless fertilization occurs.

ootid

(ō′ə-tĭd′)
n.
A haploid cell that results from the meiotic division of an oocyte and becomes a female gamete or an ovum.

ootid

[ō′ətid]
Etymology: Gk, ootidion, small egg
the nearly mature ovum after penetration by the spermatozoon and completion of the second meiotic division but before the fusion of the pronuclei to form the zygote. It is one of the four cells resulting from oogenesis. See also meiosis, oogenesis.

o·o·tid

(ō'ŏ-tid)
The nearly mature oocyte after the first meiotic division has been completed and the second initiated; in most higher mammals (including humans), the second meiotic division is not completed unless fertilization occurs.
[G. ōotidion, a diminutive egg. See -id (2)]

ootid

the cell produced by meiotic division of a secondary oocyte, which develops into the ovum. In mammals, this second maturation division is not completed unless fertilization occurs.
