Female Sex Hormones A woman’s body has two major hormones that regulate the monthly cycle. Each cycle has the purpose of producing children. The two main hormones that regulate the cycle and determine fertility are estrogen and progesterone. Each of these main hormones plays a big role in our reproductive health.The newborn male or female has estrogen in their own system for their mother.A female child gets more estrogen produced as they get mature. At puberty the estrogen causes breast development and the maturation of the vagina and ovaries.
Fetal Blood Flow The process of gas exchange between the mother and an unborn baby has several steps. A large flat organ that is inside the uterus of a pregnant women is called the placenta. The placenta is attached to the fetus which is through the umbilical cord. The placenta is a very important function during the pregnancy of a women. The transfer is very vital in enabling the right nutrients that are transported through to the mother from the placenta and then to the fetus which dismisses waste that is produced by the fetus then goes back through the placenta than into the maternal blood stream which it is then released by the mother.
An understanding of the normal embryology as well as the mechanism of anomaly production will greatly enhance the clinician's ability to diagnose such conditions. The mullerian ducts and the urogenital sinus are the primordial anlage of the female reproductive tract. The mullerian ducts differentiate to form the fallopian tubes, uterus, cervix, and the upper vagina, while the lower part comes from the urogenital sinus. The development of the gonads are independent from that of the genital tract, hence women with reproductive tract anomalies may have normal functioning ovaries. On the other hand, genital tract development is closely associated with the development of the urinary system, thus, reproductive tract anomalies may be associated with anomalies of the kidneys, ureter or bladder.
By definition, a “Designer Baby” is a genetically modified, unborn child. Basically, they are children who have been “designed” with the desired sex or characteristics. Scientists continue to learn more about the human genome, and as they do reproductive technology continually advances to levels that we never imagined. Researchers linked to Bionet point out: Advanced reproductive techniques involve using InVitro Fertilization (IVF), which is where eggs are fertilized by sperm in ‘test tubes’ outside the mother’s body in a laboratory. The type of sperm (X or Y) that fertilizes an egg can be chosen, which is used to determine the sex and genes of the baby.
The Placenta The placenta is a temporary organ that develops in the uterus of a female during pregnancy. At maturity, it is discoid mass that is about 6-8 inches in diameter, weighs 1-2 pounds, and is about 1 ¼ inches thick in the center and tapers off towards the edges. (Gray) It separates and connects the fetus and the mother and provides a pathway for oxygen, nutrients, and wastes. The placenta is connected to the fetus by the umbilical cord and to the mother by the uterine wall. The placenta serves many critical roles as an “anchor”, barrier, nutrient transporter, respiratory organ, endocrine, and excretory organ.
Ovoviviparous, is a zoological term that refers to animals that produce eggs but retain them inside the female body until hatching occurs, so that "live" offspring are born. Humans would be considered ovoviviparous animals. The final form of reproduction is Viviparous. Viviparous is a method of reproduction in which the embryo develops inside the
The parathyroid glands are usually located in the neck behind the thyroid gland, although there are exceptions. While the baby is developing inside the mother's womb, the four parathyroids travel from the head area down to the lower neck, and usually end up near the thyroid gland. However, the parathyroid glands may not always follow this path and may end up in other locations in the neck or chest, called "ectopic" locations. About 90% of parathyroid glands are found in normal locations. For the upper (superior) parathyroid glands, the normal location is next to and slightly behind the upper part of the thyroid gland.
Risks and benefits of amniocentesis Chelsea Webb SCIN132 D011 Win 12 Professor Kennard Sproul The risks and benefits of amniocentesis Amniocentesis is an invasive procedure used to collect cells from the fetus for genetic testing. Amniocentesis is done in a pregnant woman of around 15 to 20 weeks of gestation. Amniotic fluid is the fluid around the fetus in the uterus. The procedure involves taking the amniotic fluid around the fetus to collect cells that are shed from the skin of the fetus. These cells are used in different tests like karyotype i.e., knowing the number and type of chromosomes.
The voices of the parents will be recognized. After the birth, the placenta and umbilical cord are removed. INTELLECTUAL Before birth, babies are able to recognize a mother’s voice, which develops their brain before they are born. After the sperm meets the egg,
(cancer res) Under the skin, an area of breast tissue extends into the armpit (axilla). The armpits also contain a collection of lymph nodes (glands), which are part of the lymphatic system. There are also lymph nodes just beside the breastbone (internal mammary lymph nodes) and behind the collarbone. (macm) A woman's breasts are made up of fat, connective tissue and thousands of tiny glands, known as lobules, which produce milk. If a woman has a baby, the milk is delivered to the nipple through tiny tubes called ducts, which allow her to breastfeed.
