Melatonin And The Pineal Gland
.... it a message of how much
sunlight they see, and when it's dark. The sunlight prohibits the gland from
producing melatonin, so at night, when there's no sun, the sleep-inducing
hormone is released into our bodies. Because of the pineal gland and melatonin,
humans have known to sleep at night and wake during the day since long before
the age of alarm clocks.
Humans don't produce melatotin right from birth; it is transfered in utero
to babies through the placenta. For their first few days of life, .....

or they can be negative, such as suppressed memories. Sexual abuse of children
and adolescents is known to cause severe psychological and emotional damage.
Adults who were sexually abused in childhood are at a higher risk for developing
a variety of psychiatric disorders, anxiety disorders, personality disorders,
and mood disorders. To understand the essential issues about traumatic memory,
the human mind’s response to a traumatic event must firs .....

Gregor Mendel's Theories Of Genetic Inheritance
.... Different alleles will create different variations in
inherited characters. The sescond idea is that for each character, an organism
inherits two genes, one form each parent. So this means that a homolohous loci
may have matching alleles, as in the true-breeding plants of Mendel's P
generation(parental). If the alleles differ, then there will be F hybrids. The
third idea states that if the two alleles differ, the receessive allele will
have no affect on the organism's appearance. So a F hybrid plant .....

Mononucleosis
.... protein that enable them to enter cells. Viruses are
unable to multiple outside of cells. Mono is found in the DNA in the body.
Another name for mononucleosis is glandular fever because of the fever and
swelling of the lymph nodes throughout the body. What causes mononucleosis is
the Epstein-Barr virus (EBV), which is like herpes. The herpes virus also
causes some cases of mono and other diseases. Mono usually occurs in adults 15
to 30 years old, but is known to appear at any age.
Mono symptoms incl .....

How Moods Are Affected By The Sun
.... a vivid description of the effects of prolonged darkness on the human
psyche: "The curtain of blackness which has overfallen the outer world has also
descended upon the inner world of our souls," Cook wrote in his journal on May
16, 1898, "Around our tables . . . . men are sitting about sad and dejected
lost in dreams of melancholy. For brief moments some try to break the spell by
jokes, told perhaps for the 50th time. Others grind out a cheerful philosophy;
but all efforts to infuse bright hopes fail. .....

Morality And The Human Genome Project
.... them. A Genome is "the total of an individuals genetic
material," including, "that part of the cell that controls heredity" (Lee,4).
Subsequently, "reasearch and technology efforts aimed at mapping and sequencing
large portions or entire genomes are called genome projects" (Congress,4).
Genome projects are not a single organizations efforts, but instead a group of
organizations working in government and private industry through out the world.
Furthermore, the controversies surrounding the Human Genome P .....

Definition Of The Oedipus Complex
.... if they
love, their fathers. He found his own unconscious wish to murder his father in
his intensive self analysis in 1897, shortly after the death of his father.
Freud says it is only the male child that we find the fateful
combination of love for the one parent and simultaneous hatred for the other as
a rival. Freud believed Oedipal was a normal part of human psychological growth
and it is during this stage children produce emotional conflicts.
Other psychoanalysts believed that girls experience a .....

Herpes-Simplex: Type 2
.... has actually been developed.
The second type of the herpes simplex virus, however, is the usual cause
of genital herpes. Herpes infections of the genital area have become
increasingly common, going along with a rise in general of many sexually
transmitted diseases. Sometimes accompanied by headache and fever, the condition
usually begins with a mild itching, followed by the development of clusters of
blisters that break and crust to form scabs that eventually dry up. The process
may last one to .....

Multiple Births

single pregnancy, to survive in medical history were the Dionne quintuplets.
The use of drugs that treat female sterility, or fertility drugs, may
increase the chances of giving birth to multiple children. These drugs cause
the ovaries to release an egg once a month but in some cases they release more
than one egg, sometimes releasing several at a time, increasing the chances of a
multiple birth. The drug clomiphene citrate is one of the most widely taken
fertility drug and has resulted in the bir .....

AIDS
.... HIV infected by 90%. Although this
protection is not 100% it is the only way that actually helps prevent you from
getting the virus. I think that society should make condoms more accessible to
young people, I believe they should have condom machines in girl and guys school
bathrooms. I also feel that they should be distributed in school social events
such as dances or proms, when it is most likely that they will be having sex.
Giving youth condoms is not encouraging sex, in my opinion yet it is educate .....

AIDS

the early 1990s but had not yet developed clinical symptoms. In addition,
although the vast majority of documented cases have occurred in the United
States, AIDS cases have been reported in about 162 countries worldwide. Sub-
Saharan Africa in particular appears to suffer a heavy burden of this illness.
No cure or vaccine now exists for AIDS. Many of those infected with HIV may not
even be aware that they carry and can spread the virus. It i .....

Female Genital Mutilation: Long Term Psychological Effects
.... however, it continues to be practiced in Africa and the
Middle East mostly due to social forces. New reasoning developed through the
years to keep the ritual going on. The many reasons given for the practice are
bewildering and unfounded in any scientific or medical fact. They fall into four
main categories: psycho-sexual, religious, sociological and hygienic. Among the
psycho-sexual reasons is a belief that the clitoris is an aggressive organ that
threatens the male organ and even endangers babies .....

Muscle Growth

of the body weight in men. With over 600 muscles covering the human skeleton
muscles give the body bulk and form. Then human body contains millions of
muscle fibres whose coordinated contraction cause the whole muscle to contract.
Muscles are the foundation on which our bodies are built. Without muscles our
bodies could not perform the simplest tasks such as opening our eyes, talking,

Haemophilia

a hereditary disorder in which bleeding is due to deficiency of the coagulation
factor VIII (VIII:C)3. In most of the cases, this coagulant protein is reduced
but in a rare amount of cases, this protein is present by immunoassay but
defective. Haemophilia A is the most common severe bleeding disorder and
approximately 1 in 10,000 males is effected. The most common types of bleeding

Alcohol Consumption By Adolescents
.... by adolescents is frequent, alcoholism is very rare.
Still, alcohol consumption by adolescents hinders normal development. Alcohol
intake by children can result in learning impairment, hyperactivity, and
personality and behavior problems, because today's society has accepted the
casual use of alcohol (Effects, 1996, 1). Among men, research suggests that
greater alcohol use is related to greater sexual aggression (Shalala, 1995, 2).
Students living on campuses with higher proportions of binge drinkers expe .....
