Final answer:
The correct answer to the question is 2) follicle cells, as they do not enter the uterine tube with the ovum and cumulus oophorus cells after ovulation.
Step-by-step explanation:
After ovulation, only the ovum (secondary oocyte) and the surrounding cumulus oophorus cells enter the uterine tube, not the follicle cells. This is because, during ovulation, the mature follicle bursts open and the secondary oocyte, which starts meiosis II, is released from the ovary and caught by the uterine tube, typically the distal (far) end called the ampulla, where fertilization often occurs. The secondary oocyte is accompanied by cumulus oophorus cells, which include the corona radiata. The corona radiata and the inner zona pellucida remain with the oocyte upon ovulation, while the remaining follicle cells do not follow the oocyte into the uterine tube.
The correct answer to the question "Only the ovum and cumulus oophorus cells enter the uterine tube not the _______." is option 2) follicle cells.
