| ARTICLES RELATED TO arteries | | | |  arteries: Encyclopedia II - Aortic dissection - OverviewAs with all other arteries, the aorta is made up of three layers. The layer that is in direct contact with the flow of blood is the tunica intima, commonly called the intima. This layer is made up of mainly endothelial cells. Just deep to this layer is the tunica media, known as the media. This "middle layer" is made up of smooth muscle cells and elastic tissue. The outermost layer (furthest from the flow of blood) is known as the tunica adventitia or the adventitia ...

| | | | | arteries: Encyclopedia II - Subdural hematoma - Treatment It is important that a patient receive medical assessment, including a complete neurological examination, after any head trauma. A CT scan or MRI scan will usually detect significant subdural hematomas.
Treatment of a subdural hematoma depends on its size and rate of growth. Small subdural hematomas can be managed by careful monitoring until the body heals itself. Large or symptomatic hematomas require a craniotomy, the surgical opening of the skull. A surgeon then opens the dura, removes the blood clot with suction or irrigation, and ...

| | | | | arteries: Encyclopedia II - Siphon - Use Bowl siphons are part of flush toilets. Siphon action in the bowl siphon siphons out the contents of the toilet bowl and creates the characteristic toilet "sucking" sound. Some toilets also use a siphon for the actual flush from the storage tank.
An inverted siphon is not a siphon but a term applied to pipes that must dip below an obstruction to form a "U" shaped flow path, see also culvert. At no point does the siphon effect come into play; an inverted siphon will work fine in the absence of atmospheric pressure. Liquid ...

| | | | | arteries: Encyclopedia II - Radiosurgery - Radiosurgery of brain tumors Radiosurgery has been especially helpful for the localized, highly precise treatment of brain tumors. Due to the steep fall of the irradiation fields (isodoses) from the center of the target to be destroyed, the biological inactivation happens only on it; while the brain, and other vascular and neural structures around it, are protected. This is achieved through the high mechanical precision of the radiation source, and the assured reproducibility of the target. The precision in the positioning of the patient, in the calculation of dosag ...

| | | | | arteries: Encyclopedia II - Siphon - Biological siphons Biologists debate whether the siphon mechanism plays a role in blood circulation [21]. It is theorized that veins form a continuous loop with arteries such that blood flowing down veins help siphon blood up the arteries, especially in giraffes and snakes[22]. Some have concluded that the siphon mechanism aids blood circulation in giraffes [23]. Many others dispute this[24][25] and experiments sho ...

| | | | | arteries: Encyclopedia II - Nitroglycerin - Detonation Nitroglycerin and any or all of the diluents mentioned above can certainly deflagrate or burn. However, the explosive power of nitroglycerin is derived from detonation: a shock propagates through the fuel-rich medium at a supersonic speed. In other words, the initial decomposition sets up a pressure gradient that induces decomposition in contiguous material, creating a fast-moving transition zone, which (due to the nature of the material) can detonate any unstable or explosive material it encounters. This generates a self-sustained cascade o ...

| | | | | arteries: Encyclopedia II - Radiosurgery - History Radiosurgery started with Dr. Lars Leksell from the Karolinska Institute of Stockholm, Sweden, in 1949, in a joint development with Bjorn Larsson, a radiobiologist from Uppsala University. Leksell initially used heavy particles, protons from a to irradiate brain tumor lesions.
In 1968, they developed the "gamma knife", a new device exclusively for radiosurgery, which consisted of radioactive sources of Cobalt-60 placed in a kind of helmet with central channels for irradiation, using gamma rays. In the last version of this device, 201 sources of radioactive cobalt direct gamma radiation to the center of a helme ...

| | | | | arteries: Encyclopedia II - Penis - Linguistics
Penis - Etymology.
The word is derived from the Latin word for tail, also used to describe the organ, "penis". The Latin word "phallus" (from the Greek "phallos") is sometimes used to describe the penis, though the word originally was used to describe images, pictoral or carved, of the penis [1].
Some derive the Latin word penis from earlier *pesnis, and the Greek word peos = "penis" from earlier *pesos.

| | | | | | | arteries: Encyclopedia II - Albert von Kölliker - Life Albert Kölliker was born in Zurich, Switzerland. His early education was carried on in Zurich, and he entered the university there in 1836. After two years, however, he moved to the University of Bonn, and later to that of Berlin, becoming a pupil of noted physiologists Johannes Peter Müller and of Friedrich Gustav Jakob Henle. He graduated in philosophy at Zurich in 1841, and in medicine at Heidelberg in 1842. The first academic post which he held was that of prosector of anatomy under Henle, but his tenure of this office was brief - in 1 ...

| | | | | arteries: Encyclopedia II - Nitroglycerin - Instability and desensitization In its pure form, it is shock-sensitive (i.e., physical shock can cause it to explode) and degrades over time to even more unstable forms. This makes it highly dangerous to transport or use. In this undiluted form it is one of the most powerful high explosives, comparable to the military explosives RDX and PETN (which are not used in munitions at full concentration because of their sensitivity) as well as the plastic explosive C-4.
Early in the history of this explosive it was discovered that liquid nitroglycerin can be "desensitized" ...

| | | | | | arteries: Encyclopedia II - Subdural hematoma - Risk factors Factors increasing the risk of a subdural hematoma include very young or very old age. As the brain shrinks with age, the subdural space enlarges and the veins that traverse the space must travel over a wider distance, making them more vulnerable to tears. This and the fact that the elderly have more brittle veins make chronic subdural bleeds more common in older patients (Downie, 2001). Infants, too, have larger subdural spaces and are more predisposed to subdural bleeds than are young adults (Wagner, 2004).
Other risk factors for subdural bleeds include taking blood thinners (antic ...

| | | | | arteries: Encyclopedia II - Radiosurgery - Definition and applications Radiosurgeons make use of highly sophisticated, highly precise and complex instruments, such as stereotactic devices, linear accelerators, computers and laser beams. In the last 20 years, radiosurgery has been used as a first approach, by exclusion or failure of other techniques or as supplements to them, such as other kinds of brain surgery, chemotherapy and radiotherapy. The highly precise irradiation of targets within the brain is planned by the surgeon with basis on images, such as computed tomography (CT), magnetic resonance imaging (MR ...

| | | | | arteries: Encyclopedia II - Bat - Vector for rabies The following advice is only relevant to areas with endemic rabies.
Only 0.5% of bats carry rabies. However, of the very few cases of rabies reported in the United States every year, most are caused by bat bites. Although most bats do not have rabies, those that do may be clumsy, disoriented, and unable to fly, which makes it more likely that they will come into contact with humans. Although one should not have an unreasonable fear of bats, one should avoid handling them or having them in one's living space, as with any wild an ...

| | | | | arteries: Encyclopedia II - Bat - Cultural aspects The bat is sacred in Tonga and West Africa and is often considered the physical manifestation of a separable soul. Bats are closely associated with vampires, who are said to be able to shapeshift into bats, fog or wolves. Bats are also a symbol of ghosts, death and disease. Among some Native Americans, such as the Creek, Cherokee and Apache, the bat is a trickster spirit. Chinese lore claims the bat is a symbol of longevity and happiness, and is similarly lucky in Poland and geographical Mac ...
