Endorphins definition What are endorphins
Endorphin is a chemical substance made of proteins and produced in the pituitary gland of the brain. It acts on the central and the peripheral nervous systems in suppressing pain.
Enkephalin is a type of endorphin and also a natural pain killer, working to inhibit the transmission of pain in the pathway for pain perception. This lessens the emotional and the physical impact of pain.
Research is revealing how these two natural opiates might also serve other roles.
Enkephalin might be involved in the development of psycho-pathological behavior in some people. Endorphin might also exert profound effects on moods, higher production being associated with a persons sense of well-being.
Increased levels of these chemical substances might also prevent an immune system from being weakened by such psychological states as depression or bereavement.
People prone to depression, alcoholism, or drug addiction are often deficient in endorphin levels.
How to increase endorphin levels?
Regular aerobic exercise is believed to elevate endorphin levels.This is the so-called “runner’s high”.
Meditation, prayer and relaxation response training also elevate endorphin levels.
Hormone definition for kids What are Hormones

How tall you grow depends mostly on chemical substances called hormones, which move around your body in your blood.
Some hormones cause the cells in your body to make more protein. They then make the cells grow and divide, so that all of your body gets bigger.
Because hormones are going around in your blood, they reach every cell in your body. So all your cells grow and divide at your normal rate.
Can you imagine how it would be if some-parts of your body grew faster than others?
This is why hormones are so important.
Hormones control the different parts of your body, so that everything is regulated. Hormones are regulators of chemical and growth activity in the body.
A special kind of hormone, called growth hormone, helps the long bones to grow. Children who do not produce enough of this hormone may not grow as tall as they would be able to grow with the hormone.The balance of hormones in your blood is controlled by the pituitary gland, which lies just below the brain.
The pituitary gland produces hormones which control many of the body’s activities.
Large numbers of nerve cells and blood vessels link the pituitary gland to a part of the brain called the hypothalamus. The hypothalamus controls the pituitary gland by sending “on” and “off ” messages through the nerve cells and the bloodstream.
These messages affect the pituitary gland with regard to the releasing of its hormones.

Top Ten Books I Just Had to Buy But Are Still Sitting on My Bookshelf

Well, this weeks Top Ten Tuesday list by The Broke and the Bookish was ridiculously easy. All I had to do was scoot over to my bookcase and pick up the row of books Ive been meaning to read and never have...and if Im truthful, most likely never will. Sigh.
Here they are, in alphabetical order by authors last name.
1. Herbert Rowbarge by Natalie Babbitt. I bought the paperback edition sometimes in the 80s and it has moved from bookshelf to bookshelf from apartment to house to apartment to house to house. I bought it because I loved Natalie Babbitss outstanding childrens novel Tuck Everlasting. But for some reason I have never cracked this one open so I cant even say what its about. I keep it because Ive had it so long. Silly reason, I know.
2. Arthur & George by Julian Barnes. I love detective fiction and I love Victorian settings. After seeing many good reviews, I snatched up a copy, which remains unread.
3. Possession by A. S. Byatt. This one is not actually on my bookshelf. Somehow I ended up with two hardcover copies, and after years of them both sitting reproachfully on my shelf, I finally donated them to a library. I did start the novel and did not like it. The Childrens Hour, her latest, has gotten rave reviews. I may give it a try, but a library copy this time.
4. Madame Bovary by Gustave Flaubert. Dont remember how I even came to own this one. Its a classic and I really should read it, I know. But there it sits on the shelf.
5. The Graveyard Book by Neil Gaiman. Bought the hardcover edition after it won the Newbery Award. Again, right up my alley as I love ghosts, graveyards, etc. This one, though, I swear I will read--and soon.
6. Freddy and Frederick by Mark Helprin. Bought this at a used bookstore for one dollar. According to the jacket flap, its a funny allegory about fictional members of the British royal family. But its more than 500 pages long!
7. The Remains of the Day by Kazuo Ishiguro. Another one Ive had for years. I think I started it once, then put it down. Maybe Ill watch the movie.
8. The Portrait of a Lady by Henry James. I know, I know; its a classic. But Im not a fan of Henry James. This novel is supposed to be one of his more accessible ones. I started it, but it was a snore. Sorry, Henry James fans.
9. Angelas Ashes by Frank McCourt. Everyone has read this memoir, even people who are not particularly bookish. Except me. I know I would like it, too. So why does it remain unread? I think because when everyone was busy reading it, I wasnt. Now it feels like I missed the bus.
10. Atonement and Saturday by Ian McEwan. Yes, not one, but two of his novels sit on my shelf, unread. Both books have interesting subjects and good reviews. They just didnt click with me.
So theres my shameful list. What untouched books sit on your shelves? Confess!
