What else can I help you with?
When a primary oocyte divides a secondary oocyte and what are produced?
A primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte undergoes meiosis II to produce a mature ovum (egg) and another polar body.
Is It the secondary oocyte and not the egg that the sperm fertilizes?
Yes, it is the secondary oocyte that the sperm fertilizes. The secondary oocyte completes meiosis II to become a mature egg only after fertilization.
When the primary oocyte divides a secondary oocyte and what else is produced?
The primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte then goes through meiosis II to produce a mature ovum (egg) and another polar body.
Which hormone assumes a role in the development and discharge of a secondary oocyte?
The hormone that plays a crucial role in the development and release of a secondary oocyte is luteinizing hormone (LH). It is released by the pituitary gland and triggers ovulation, the process by which the mature ovarian follicle releases the secondary oocyte.
What transports secondary oocyte toward uterus?
The fallopian tubes transport the secondary oocyte from the ovary toward the uterus. This process is facilitated by ciliary movement and muscular contractions within the fallopian tubes, which help propel the oocyte towards the uterus for potential fertilization.
What are the structures for the pathway of a secondary oocyte?
In what order does the pathway of a second Oocyte ampulla of uterine, body of uterus, fimbriae of uterine tube, fundus of uterus, infundibulum of uterine tube, isthmus of uterine tube and ovary
When a primary oocyte divides a secondary oocyte and what are produced?

Is It the secondary oocyte and not the egg that the sperm fertilizes?
Yes, it is the secondary oocyte that the sperm fertilizes. The secondary oocyte completes meiosis II to become a mature egg only after fertilization.
In what phase of meiosis is a secondary oocyte arrested?
A secondary oocyte is arrested in the metaphase II phase of meiosis.
At what stage of development does a secondary oocyte arrest in?
A secondary oocyte arrests in the metaphase II stage of development.
When the primary oocyte divides a secondary oocyte and what else is produced?
The primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte then goes through meiosis II to produce a mature ovum (egg) and another polar body.
When will a secondary oocyte complete meiosis II?
A secondary oocyte will complete meiosis II after fertilization by a sperm cell.
What happens to secondary oocyte once its released from the follicle?
Once the secondary oocyte is released from the follicle during ovulation, it enters the fallopian tube. If a sperm cell fertilizes it, the secondary oocyte completes meiosis II, resulting in a mature ovum and a second polar body. If fertilization does not occur, the secondary oocyte will eventually degenerate and be reabsorbed by the body within 24 hours.
What is the difference between ovum and secondary oocyte?
ovum is the product after the secondary oocyte fuses with sperm
When does the secondary oocyte develop into a ovum?
The secondary oocyte develops into an ovum during the process of fertilization. When a sperm successfully penetrates the secondary oocyte, it triggers the completion of meiosis II, resulting in the formation of the ovum and a second polar body. This transition typically occurs within the fallopian tubes shortly after ovulation. If fertilization does not occur, the secondary oocyte will not complete meiosis and will be expelled during menstruation.
Which hormone assumes a role in the development and discharge of a secondary oocyte?
The hormone that plays a crucial role in the development and release of a secondary oocyte is luteinizing hormone (LH). It is released by the pituitary gland and triggers ovulation, the process by which the mature ovarian follicle releases the secondary oocyte.
What is the name for the expulsion of the secondary oocyte from the ovary?
Ovulation
