Minor Site: http://www.pregnancycare-center.org/stagesofdevelopment.htm

This site is a good minor site for the fetal development topic because it just gives us a brief overview of some of the major stages in the developing fetus. It explains it to us in simple terms and also gives us some great graphics to go along with each stage it is describing.
This site is from the South Central Pregnancy Center. It is a nonprofit organization that offers support and assistance to anyone going through a pregnancy. They give free pregnancy tests and offer any kind of assiatnce for mothers to be from information about abortion and even adoption. They even refer you to other medical care. They just offer any basic type of information on pregancy and thats also what there site is for.
At day 1the sperm joins with the egg and becomes fertilized to form one cell which now inherits 23 chromosomes from each parent and has its genetic blue print. It starts forming the brain and spinal cord. At day 21 its heart begins to beat and by day 28 its begun to form arms and legs. At 1 month the embryo is now 10,000 times bigger than the beginning cell. By day 35 and 40 you can see the baby’s fingers formed and you can now detect and record brain activity. By weeks 7and 8 the baby begins to move spontaneously and the fetus now has everything that you will find in an adult structurally.
Now at week 10the uterus is doubled in size and things like baby’s fingerprints are now evident in the mothers skin. The fetus now does things like swallow and sleep and awaken. And it even open and closes it mouth now. Another thing that begins to occur is urination of the fetus. By week 14you can now tell whether it will be a male or female baby. You can now see fine hair develop on baby’s head and its said that the baby can now hear any external noises including moms voice. Here the umbilical cord is recorded to bring 300 quarts of fluid to the baby. Here the fetus is about eight to ten inches long
By the fifth monthhalf of the pregnancy is over and the fetus is now up to about 12 inches long. The fetus may move a lot due to external sounds and mother can now feel all of these movements very well. By month seven the baby is using all of its senses: hearing, touch, vision, and taste. By month eight its skin thickens for insulation and nourishment and the baby is almost ready to come out. Finally by nine monthsapproximately 280 days the fetus is ready to be delivered. They are now about 6 to 9 pounds and can survive completely outside the mothers womb.

Major Site http://www.dushkin.com/connectext/psy/ch03/stages.mhtml

This site is definetly a great major website. The website is actually information from a psychology book. It has pictures of all the months of a growing fetus. By going to the bottom of the screen there is actually arrows that will take you to other portions of this site. The Developing Fetus page shows you 3 photographs of how a fetus is born. You can find out about miscarriages and how to prevent your fetus from certain abnormalties.

Stages of Prenatal Development

On the first month, fertilization starts which the egg then plants itself in the wall of the uterus. The cells in the egg start to divide rapidly out of control. The nervous system develops and the fetus is only about a 1/2 inch long.
The second month you have the heart and blood vessels forming as well as your limbs, head, and eyes. Your heart starts to beat very faintly and your internal organs start to grow into place.
The third month the head of the fetus becomes bigger and the bones begin to form. The digestive organs start to function. The fetus at this level is 3 inches long and weighs approximately an ounce.
During the fourth month, lower parts of the body show rapid growth, you are able to see the bones in an XRay. Also during this time, you can actually hear the heartbeat. All the organs are completely formed. Fetus is 7 inches long and weighs 5 ounces.
The fifth month is when the mother begins to feel the baby moving within her. Fingernails and toenails begin to appear as well as cartilidge around the ears and nose. The fetus shows hiccups, thumb sucking, and kicking. Fetus is 12 inches long and weight 14 ounces.
The sixth month, the eyes and eyelids are completely formed. You also have the formation of fat under the skin. By this stage the fetus is 14 inches long and weighs 2 pounds.
The seventh month is when the cerebral cortex of the brain develops rapidly. Fetus is 17 inches long and weighs 3 pounds.
The eighth month shows subcutaneous fat which is deposited for later use. Fingernails reach beyond the fingertips. Fetus is 17 inches long and weighs 5 pounds.
The ninth and final month is when the hair covering the entire body sheds, all the organ system function the way they are suppose to, and the fetus gets settled in order to be born. At the end of pregnancy, the baby is approximately 21 inches long and weighs 7 pounds.

Although this wedsite is about the fetal pig, i found it interesting. The graphics are good and the site is set up in three sections. 1. Anatomy, 2. Estrous cycle and 3. Embyonic and Fetal development. This website was designed by Dr. Wayne Singleton and Dr. mark Diekman and is about reproduction, physiology and anatomy of the sow. It is an understanding of the sows reproductive sysytem, and how it is essential for a successful mating program. A program that is held at the purdue university. This site provides beautiful dissections that are fresh and not what we have viewed in lab.
The anatomy part of this website goes on to explain that the ovaries are the main structures of fetal develpoment. They have 2 major function which are to produce hormones and ova. the infundibulum is the membrane around the ovary and the oviduct is the site for fetilization. The cervix is the site where sperm is deposited and the uterine horns are the passage ways for sprem to meet the ovum.
Estrous cycle, Estrus and Ovulation
The estrous cycle in the sow is normally a 21 day cycle. Non pregnant pigs display a estrus or standing heat throughtout the year. While the sow is nursing her young the estrus cycle will not be present. Follicles are formed on each ovary as the estrus approaches. Follicular growth is influenced by hormones from the pituitary gland. Granulosa cells within the follicle secretes estrogen which is responsible for estrus.
Fertilization, Embryonic and Fetal Development
Although 30-60 million sperm are deposited into to cervix, only a small percentage reach the oviduct.sperm can swim on there own so the cervix with its contractions help the sperm on their way. when fertilization happens the blastocysts enter the uterus and can migrate from one horn to another. The embryo is surrouneded by a serious of fluid filled membranes. Fetal orientation is random, meaning the fetus are facing different directions. Embryos which die become reabsored. The average geatation period from conception to birth is 114 days and the fetus is about 3 to 3 1/2 pounds.

I believe this site to be a major site for fetal development. The site is designed by the westside pregnancy resource center. While surfing the web for fetal development I had come across many sites that refer back to this site. This site gives detailed descripiton of the developing embryo to fetus. It also provides colored pictures. For 30 years, this website provides a life-affirming support to both women and men who finds themselves in an unplanned pregnancy or hurting from previous abortion, or in need of sexual/ralational guidance. They are a non-profit, non-political, non-denominational organization funded entirely by privite donations and small grants. It is run solely on a small goup of staff and a handfull of volunteers. This center is the only kind in west Los Angeles and all services are free and confidential.They also provide many free services from home clinics to confidential counseling. Westside also has many links of articles and online resources about sex, pregnancy,adoption, abortion and the developing fetus, which I will disscus in this blog. there is also a hotline for anyone who is in need of counseling.
The first trimester During this stage the the sperm joins the egg in the fallopian tube and becomes fertile. The Once fetilization takes place the blastocyst burrows beneath the surface of the uterus where it will grow into a fetus. By week three the backbone, spinal column and nerous system are developing rapidly. Hormones are produced to stop the expecting mothers menstrul cycle. The heart begins to beat at 5 weeks and by the seventh week facial hair appears as well as muscle system development. The embryo is called a fetus by the end of the 8th week.
The second trimester This trimester is when the fetus muscles begin to develop and the mother can feel the kicking within her womb. Taste buds, eyebrows, and eyelashes are appearing around 15-16 weeks after conception. By 20 weeks the fetus now has fingernail and fingerprints. When having an ultrasound done during this stage one can see the sex organs of the fetus. The mothers voice can be recognized the fetus.
The third trimester In this semester the fetus begins breathing by inhaling the amnionic fluid into the developing lungs. By 38-40 weeks the baby is approximately seven to seven and a hald pounds and is ready for delivery.

Mozart- where did your body go?

The Mozart Myths: A Critical Reassessment, by William Stafford (TPB, 1991, $1.50)

Who would have known there were all those rumors of stuff going on during Mozart's last days! What I like about this author is his refusing to decide what happened. Of course we will never know what really happened, but it is so refreshing that an expert admits it.

So, what are the myths? Let's see-

1. Was he poisoned?- almost certainly not
2. Was he anti-Semitic?- probably not, but maybe?
3. Was he melancholy and self-destructive just before he died? He was certainly exhausted, probably dealing with heart failure brought about by rheumatic fever, and massively in debt.
4. Did he see himself as a genius or a failure?  A failure? How could he thought himself a failure? He had been a child prodigy, and as a young adult, a successful composer and performer. As he got older, though, his works were seen as too old-fashioned. People stopped buying his music. Before he died only 20% of his compositions were in print. Then he died, and people became interested again in his music. Both his widow and his son would be able to live lives of leisure. So as he was dying how did he see himself? We will never know.
5. Did he know he was dying when he composed his last work, the Requiem? Did he really push himself to exhaustion to finish it before he died? Did he hear a rehearsal of Requiem on his last afternoon? - Most likely not, since when he died the work was still not finished.
6. Did the weather get suddenly dark and stormy when he died? - Nope!
7. Was he buried in a pauper's grave? Is that why his grave site is unknown?- Nope. Actually during this time no one had lavish burials. Most of the middle-class were buried in wooden coffins, five to a grave, marked only by a wooden marker. Many times when more burial space was needed, bodies, including Mozart's, were dug up, the bones crushed, and then reburied elsewhere. By that time even his wife didn't know where his remains were. To complicated matters, in 1855 a marker was put up where people thought his body might be. Later, the marker was moved again. (And please don't ask about his supposed skull, and how it ended up separate from his body!) So, to summarize, his was not a pauper's grave, but where it is no one, even now, knows.

How weird is all this? Read more about this in the book, to be found on the new non-fiction table. (9/20)        (L-mu)
