William Harvey – anatomist and physiologist
William Harvey – anatomist and physiologist – In 01. 04. 1578 was born anatomist and physiologist William Harvey. As the first, in 1628 described the construction and operation of the bloodstream. He showed that the contraction of the heart is the origin of the muscle. His discoveries made through experiments on dogs. The result of his discoveries were the first, unsuccessful transfusions and dissemination of treatment bloodletting.
Synthetic exendin – Eli Lilly & Co. has developed synthetically exendin – 4. Previously only obtainable from the saliva of the Gila monster (Heloderma suspectum) – one of two venomous lizards in the world. Living in the deserts of the north – western Mexico and south – western United States. During the manufacturing process used the latest methods of biogenetics. Exendin is intended for the treatment of type 2 diabetes has become a forerunner in a new series of drugs known as mimetic (imitation) incretin. They imitate the action of incretin hormones found in nature. In addition to the pancreas incretins also affect other organs in connection with the regulation of glucose – liver, kidney, muscle and brain.
Women on dance floor
Women on dance floor – According to Bernhard Fink, an evolutionary psychologist and anthropologist at the University of Göttingen, women during ovulation dance more sensual. Their more attractive during ovulation is the result of physiological changes that are primarily associated with an increase in estrogen levels.
“Estrogen affects the control of muscles, ligaments, tendons and the whole locomotor system, which implies that may also affect the way we move the body.”
– says Fink.
Bluefin tuna – Cold-blooded fish
Bluefin tuna – Although the bluefin tuna (Thunnus thynnus) is a Actinopterygii fish, most of which are cold-blooded, their body is from 6 to 20 degrees Celsius warmer than the surrounding sea water. This heat is generated within the muscle – and with them, mainly built tuna.
Spiders movable retina – rotated in all directions
Spiders movable retina – In contrast to the eyes of vertebrates, retina spiders Salticidae is movable. Thanks to three pairs of muscles can be rotated in all directions and move. Panoramic image obtained by all pairs of eyes, cover 360 degrees.
How many calories needs brain?
How many calories needs brain ? – The brain represents approximately 2% of our body weight, but consumes 20% of total energy demand – a day so it is up to 500 calories. Most of the energy spent on the brain processes occurring in the body, such as directing muscles. This is because during sleep our body burns far fewer calories than awake.
Older age becomes easier – Faster new muscle cells
Older age becomes easier – Faster formation of new muscle – Just three days noticeably increase the dose of daily traffic to enable efficient metabolism. With age, it is becoming easier, the older man, the faster formation of new muscle cells. They break down the sugar, thereby reducing the risk of diabetes and atherosclerosis.
Normally heart muscle – Heart rate healthy adult man
Normally heart muscle – Heart healthy adult human beats per minute 60 to 80 times. Resting pulse of 60 is regarded as a guarantee of a healthy heart for many years. It protects the vessels and thus minimizes the risk of cardiovascular disease and heart. If the pulse is constantly oscillates between 81 and 90, the risk of death – by. Danish studies – is 2x higher, and with over 90 increases almost 3x.
Hot time ambulance service – Falls between 9 – 10 am
Hot time ambulance service – Falls between 9 am and 10 am. This peak phase lasted from 6 to 12, which occurs 40% of fatal heart attacks. Responsible for this is a protein called Klf15, the system clock of the heart. In the morning it provides increased supply of potassium to the heart muscle, increasing blood pressure.
Human skeleton contains 206 bones
Human skeleton contains 206 bones – Each healthy subject Homo sapiens has 206 bones and including hearing bones – 212. Infants have their little more, but eventually some of the fuse. The bones represent approx. 30 – 40% of our weight. Tendons, muscles and cartilage combine all the bones in the skeleton. The spine supports the parts of the skeleton and gives our body flexibility. All 24 circles under the cross “sit” in the back like a spring tension, are linked by strong ligaments, intervertebral discs (ie. Discs) and a lot of muscle. Spine keeps us upright and better cope with shocks than many a shock absorber in the truck.
