What is the usual site of the fertilization of an egg cell?
Fertilization of an egg normally occurs within the uterus.
The scrotum helps keep the testes cooler than body temperature, a condition necessary for normal sperm production.
If fertilization does not occur the corpus luteum will degenerate.
What is the correct sequence of the journey for mature sperm?
The Sperm’s JourneyDuring the ejaculation process, the mature sperm travel from the epididymis to the vas deferens. The vas deferens then joins with the seminal vesicle to form the ejaculatory duct.
Which of the following is the correct pathway for the passage of sperm?
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. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.
Where does fertilization of an egg cell 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.
Where does fertilization occur?
Fertilization occurs in the fallopian tubesFertilization takes place in the fallopian tubes, which connect the ovaries to the uterus. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote.
What is the role of the corpus luteum during early pregnancy quizlet?
What is the function of the corpus luteum during pregnancy? The Corpus Luteum continues to produce estrogen and progesterone. Progesterone is essential for maintaining endometrium and the survival of the fetus.
What is the journey of the sperm?
During sex, sperm are ejaculated into the vagina. From there, the journey begins. The sperm swim through the cervix (with the help, hopefully, of the medium of fertile cervical mucus) and move into the uterus. From one end of the womb to the other, the sperm must swim… to finally reach the fallopian tube.
How does sperm leave the female body?
After ejaculation, sperm can live inside the female body for around 5 days. Once inside the female reproductive tract, the sperm cells must swim through the cervix and into the uterus to reach the fallopian tubes and female egg. It is a very long journey for sperm cells to make and very few survive.
Where does sperm travel in a female?
The ideal time of fertilization is around ovulation when the egg is in the fallopian tube. After traveling through the vaginal canal, the strongest sperm make it to the cervix. From here, the sperm must travel through the uterus and into one of the fallopian tubes.
What is the function of the sperm cell’s acrosome?
Each sperm is a haploid cell, containing half the chromosomal complement of a normal, diploid body cell. The front of the head is an area called the acrosome. The acrosome contains enzymes that help the sperm penetrate an egg (if it reaches one).
Which is the correct pathway for the sperm quizlet?
Sperm are produced in the Testes (continuous). Sperm move to the Epididymis to mature. Sperm move the the Vas Deferens to begin traveling through the male body (“The Sperm Highway”). Seminal Vesicle adds a nutrient-rich fluid, high in fructose to the sperm making a mixture called semen.
How does sperm get ejected?
Sperm gets ejected from the penis, enters the vagina, and swims up the reproductive tract until they reach the egg to fertilize it.
Where does a sperm generally fertilize an egg?
Fertilization takes place in the fallopian tubes, which connect the ovaries to the uterus. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube.
How do sperm move to fertilize eggs quizlet?
Sperm start by traveling through the uterus and up the fallopian tubes in search of the ovum. The sperm have 24 hours after the ovum is released to fertilize the egg. the sperm travel as about 1-5 mm per minute. when the sperm reach the egg they surround its outer surface attempting to enter.
How is a sperm able to fertilize an egg?
The sperm binds through the corona radiata, a layer of follicle cells on the outside of the secondary oocyte. Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.
