The ampulla is the normal site of fertilization. B. The infundibulum is the narrow constricted region at the junction with the uterus.
Which region of the uterine tube is the normal site of fertilization?
A uterine tube contains 3 parts. The first segment, closest to the uterus, is called the isthmus. The second segment is the ampulla , which becomes more dilated in diameter and is the most common site for fertilization.
Which of the following is the normal site of fertilization?
The normal site of fertilization is the: vagina .
What region of the uterine tube is the fertilization process quizlet?
The process of fertilization involves successful fusion of the male and female gamete cells. Normally occurs in the ampullary region of uterine tube (ampulla means flask/bottle in Latin).
Where is the usual site of fertilization quizlet?
The usual site of fertilization is the uterine, or fallopian, tube .
Which side is your fallopian tube?
The fallopian tubes are muscular tubes that sit in the lower abdomen/pelvis, alongside the other reproductive organs. There are two tubes, one on each side , that extend from near the top of the uterus, run laterally and then curve over and around the ovaries.
Do fallopian tubes move between ovaries?
Amazing and little-known fact: Fallopian tubes are mobile and active parts of your reproductive tract. When one tube isn’t there or is “broken” the other tube can actually move over to the opposite ovary and “pick up” an available egg. Pretty amazing.
What are the symptoms when sperm meets egg?
Implanting gives the blastocyst a blood supply so that it can start growing into a fetus. Along with cramping, you may experience what is called implantation bleeding or spotting. This usually happens 10 to 14 days after conception , around the time of your usual period.
What are the signs of unsuccessful implantation?
- Chronic pelvic pain.
- Bowel obstruction.
- Painful menses.
- Pain during intercourse.
- Infertility.
- Increased incidence of ectopic pregnancy.
Which is the correct pathway of the sperm?
When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity , over the ureter to the prostate behind the bladder.
What are the 6 steps of fertilization quizlet?
- Sperm Capacitation.
- Sperm-Zona Pellucida Binding.
- The Acrosome Reaction.
- Penetration of the Zona Pellucida.
- Sperm-Oocyte Binding.
- Egg Activation and the Cortical Reaction.
- The Zona Reaction.
- Post-fertilization Events.
Where does an egg implant after fertilization quizlet?
The Fertilized Egg Implants Into The Uterus And Is Nourished By The Placenta. After fertilization, the zygote begins to divide through mitosis as it travels down the fallopian tube. During this time, the corpus luteum continues to secrete progesterone and some estrogen.
Where does fertilization of an egg occur quizlet?
Egg is fertilized in the Fallopian tube . It takes 3-4 days for the egg to get to the uterus. The fertilized egg (zygote) is called an embryo after it is implanted in the uterine lining.
Which pathogen within the mother is most likely to be transmitted across the placenta?
Infections at the uterine-placental interface are commonly associated with viruses, parasites and few bacteria (Table 1). Viral pathogens such as human cytomegalovirus (HCMV), Zika (ZIKV) , and rubella virus are the most common vertically transmitted pathogens through the decidual-placental interface (Table 1) (26, 27).
What happens during the first phase of fertilization?
At the beginning of the process, the sperm undergoes a series of changes, as freshly ejaculated sperm is unable or poorly able to fertilize. The sperm must undergo capacitation in the female’s reproductive tract over several hours , which increases its motility and destabilizes its membrane.
Which part of the female reproductive tract is the site of fertilization quizlet?
Where in the female reproductive system does fertilization normally take place? Fertilization occurs in the uterine tube which is where to ovulated egg goes after its process.
