Which of the following is a similarity between male and female reproductive systems?
Which of the following is a similarity between male and female reproductive systems? –They both produce haploid gametes.
What structure receives the ovulated oocyte?
The ovulated oocyte with its surrounding granulosa cells is picked up by the infundibulum of the uterine tube, and beating cilia help to transport it through the tube toward the uterus. Fertilization occurs within the uterine tube, and the final stage of meiosis is completed.
Which of the following explanations would help Angela understand how the birth control pill helps prevent her from ovulating?
Which of the following explanations would help Angela understand how the birth control pill helps prevent her from ovulating? The hormones in the pill produce negative feedback, which leads to a drop in FSH levels.
Which region is the rounded portion of the uterine body superior to the attachment of the uterine tubes?
The upper part of the uterus above the insertion of the fallopian tubes is called the fundus. The narrow portion situated between corpus and cervix is known as the isthmus and lies approximately at the level of the course of the uterine artery and the internal os of the cervix.
Are you born with a womb?
Some women are born without a uterus. In some rare cases, women are born without a uterus, this is called Mayer-Rokitansky Küster-Hauser syndrome (MRKH). Although the internal reproductive parts can be underdeveloped or missing entirely, the vulva might not look any different.
What are the differences of male and female reproductive system of different species?
The male has reproductive organs, or genitals, that are both inside and outside the pelvis, while the female has reproductive organs entirely within the pelvis.
What process occurs as the zygote travels towards the uterus in the fallopian tubes?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
Which process occurs in the uterine tube?
Overview. The uterine tubes, also known as oviducts or fallopian tubes, are the female structures that transport the ova from the ovary to the uterus each month. In the presence of sperm and fertilization, the uterine tubes transport the fertilized egg to the uterus for implantation.
What is the main difference between oogenesis and spermatogenesis in terms of meiosis?
What is the main difference between oogenesis and spermatogenesis in terms of meiosis? –Oogenesis produces three polar bodies, while spermatogenesis produces only one. -The number of functional gametes produced is different. -Oogenesis does not include a second meiotic division.
What happens to your eggs when you don’t have a period on birth control?
Birth control prevents pregnancy by preventing the release of an egg from the ovaries. If an egg isn't released, it can't be fertilized. (No egg means no fertilization and no pregnancy.) So technically, birth control makes a woman keep her eggs.
What ligaments are located in the pelvis and support the uterus and ovaries?
The uterosacral ligaments are anteriorly attached to the cervix uteri. The uterosacral ligaments are posteriorly attached to sacral vertebrae. The ovaries rest in ovarian fossa in the lateral part of the pelvic cavity next to the iliac vessels. The ovaries contain germ cells.
Which structure attaches the lateral edge of the ovary to the posterior wall of the pelvic cavity?
The suspensory ligaments attach each ovary to the pelvic sidewall. The ovarian ligaments, which connect each ovary to the lateral side of the uterus, do not contain any blood vessels. These are also known as the utero-ovarian ligaments or the proper ovarian ligaments.
Can men get pregnant?
'" Since 2000, several hoax web sites have appeared on the Internet purporting to describe the world's first pregnant man. While some rely on legitimate scientific claims, no such experiment has ever been reported.
Does everyone start off as a girl?
Geneticists have discovered that all human embryos start life as females, as do all embryos of mammals. About the 2nd month the fetal tests elaborate enough androgens to offset the maternal estrogens and maleness develops.
Are breasts reproductive organs?
The breasts are considered secondary sex characteristics because they are not organs of reproduction. They are described here because of their role in nurturing an infant after birth. As shown in Figure below, each breast contains mammary glands.
Do cows and horses have vaginas?
There are two ovaries, two oviducts, two uterine horns, a uterine body, cervix, vagina and vulva.
What is the implantation process?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
How long is the implantation process?
Implantation: what happens after the egg is fertilized It takes about 6-12 days for the fertilized egg to travel to the uterus and attach to the uterus in a process known as implantation (1,8). The egg is pushed back towards the uterus by the cilia (1). The egg must attach to the uterus to become a viable pregnancy.
Which process occurs in the uterine tube quizlet?
Which process occurs in the uterine tube? Fertilization. They transport the ovulated oocyte to the uterus.
What is the process of oogenesis and spermatogenesis?
Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into an embryo.
What is process of spermatogenesis?
Spermatogenesis is the process of sperm cell development. Rounded immature sperm cells undergo successive mitotic and meiotic divisions (spermatocytogenesis) and a metamorphic change (spermiogenesis) to produce spermatozoa.
Can you skip a period?
There are many reasons why a woman may miss her period, or why periods might stop altogether. Most women have a period every 28 days or so, but it's common to have a slightly shorter or longer cycle than this (from 21 to 40 days). Some women do not always have a regular menstrual cycle.
Why do periods come late?
Natural causes most likely to cause amenorrhea include pregnancy, breast-feeding, and menopause. Lifestyle factors may include excessive exercise and stress. Also, having too little body fat or too much body fat may also delay or stop menstruation. Hormonal imbalances may cause amenorrhea.
Where is pelvic pain?
Definition. Pelvic pain is pain in the lowest part of your abdomen and pelvis. Pelvic pain might refer to symptoms arising from the reproductive, urinary or digestive systems, or from muscles and ligaments in the pelvis.
Where is my hip bone?
One of the body's largest weight-bearing joints, the hip is where the thigh bone meets the pelvis to form a ball-and-socket joint. The hip joint consists of two main parts: Femoral head – a ball-shaped piece of bone located at the top of your thigh bone, or femur.
What ligaments are located in the pelvis and support the uterus and ovaries where do they lie?
The broad ligament supports the uterus, fallopian tubes, and ovaries. It extends to both sides of the pelvic wall….Female pelvis ligaments
- mesometrium, which supports the uterus.
- mesovarium, which supports the ovaries.
- mesosalpinx, which supports the fallopian tubes.
Which of the following ligaments anchors the ovary to the body wall of the uterus?
The suspensory ligaments attach each ovary to the pelvic sidewall. The ovarian ligaments, which connect each ovary to the lateral side of the uterus, do not contain any blood vessels. These are also known as the utero-ovarian ligaments or the proper ovarian ligaments.
How can I get twins?
Twins can occur either when two separate eggs become fertilized in the womb or when a single fertilized egg splits into two embryos. Having twins is more common now than it was in the past. According to the Centers for Disease Control and Prevention (CDC) , twin births have nearly doubled over the last 40 years.
Who is the first man that get pregnant?
Beatie had gender reassignment surgery in March 2002 and became known as "the pregnant man" after he became pregnant through artificial insemination in 2007. Beatie chose to be pregnant because his wife Nancy was infertile, doing so with donated sperm.
How many sexes are there?
two sexes Based on the sole criterion of production of reproductive cells, there are two and only two sexes: the female sex, capable of producing large gametes (ovules), and the male sex, which produces small gametes (spermatozoa).
