What do you mean by anastomosing?
An anastomosis is a surgical connection between two structures. It usually means a connection that is created between tubular structures, such as blood vessels or loops of intestine. For example, when part of an intestine is surgically removed, the two remaining ends are sewn or stapled together (anastomosed).
What is anastomosing network?
Anastomosis is defined as the joining or coalescing of different branching networks of tubes into a single continuous network. From: Heart Development and Regeneration, 2010.
How are anastomosing channels formed?
Anastomosing rivers are usually formed by avulsions, i.e., flow diversions that cause the formation of new channels on the floodplain.
What is anastomosis in fungus?
In mycology, anastomosis is the fusion between branches of the same or different hyphae. Hence the bifurcating fungal hyphae can form true reticulating networks. By sharing materials in the form of dissolved ions, hormones, and nucleotides, the fungus maintains bidirectional communication with itself.
What are anastomoses and why are they important?
Anastomoses occur normally in the body in the circulatory system, serving as backup routes for blood flow if one link is blocked or otherwise compromised. Anastomoses between arteries and between veins result in a multitude of arteries and veins, respectively, serving the same volume of tissue.
What is Nervi and Vasa Vasorum?
The adventitia houses both the intrinsic vessels (vasa vasorum) and nerves (nervi vasorum) that supply the vessel itself. The vasa vasorum allows oxygen, nutrients, and waste to move from the lumen to the cells of the vessel wall.
What is anastomosing in geography?
Description. On Earth, the term anastomosing is commonly applied to alluvial rivers that are composed of two or. more interconnected channels that enclose flood basins (Makaske 2001; Figs.
When a river system is anastomosing?
An anastomosing river can be defined as a river having multiple interconnected channels that enclose floodbasins (Makaske, 2001). Anastomosing rivers are commonly formed by avulsions, flow diversions that cause the formation of new channels on the floodplain.
What is the plural of anastomosis?
anastomosis (countable and uncountable, plural anastomoses) A cross-connection between two blood vessels. An interconnection between any two channels, passages or vessels. quotations ▼ (surgery) The surgical creation of a connecting passage between blood vessels, bowels or other channels.
Is anastomosis a noun?
noun, plural a·nas·to·mo·ses [uh-nas-tuh-moh-seez]. Anatomy. communication between blood vessels by means of collateral channels, especially when usual routes are obstructed.
What is Vasa Nervorum?
The vasa nervorum are an irregular source of nutrition that supplies each peripheral nerve from adjacent blood vessels.
What is the nervi vasorum?
Vascular nerves (nervi vasorum) are nerves which innervate arteries and veins. The vascular nerves control vasodilation and vasoconstriction, which in turn lead to the control and regulation of temperature and homeostasis.
How are anastomosing rivers formed?
How is anastomosis done?
In most cases, anastomosis can be performed using laparoscopy. Laparoscopy means that the surgery is done through a small incision using a small instrument called a laparoscope. A laparoscope is a long, thin tube with a camera and light at the end of it. It helps doctors see inside your body while they perform surgery.
What is an anastomosing river?
Anastomosing rivers constitute an important category of multi-channel rivers on alluvial plains. Most often they seem to form under relatively low-energetic conditions near a (local) base level. It appears to be impossible to define anastomosing rivers unambiguously on the basis of channel planform only.
What is an example of anastomosis?
This connection of arteries is one example of anastomosis. Anastomosis is a connection that occurs between two structures in the body. Usually these structures are hollow or tubular in shape, like the blood vessels I mentioned above. We can categorize anastomosis into three different types, so let’s take a look.
Is scroll topography a characteristic feature of anastomosing river floodplains?
Outside Australia, Baker (1978) mentioned prominent scroll topography on anastomosing river floodplains of the Solimões River. It can be concluded that, although meander belts with ridge-and-swale topography generally are not characteristic features of anastomosing river floodplains, they may be present.
How do anastomosing rivers maintain a multi-channel state?
Anastomosing rivers systems with a low avulsion frequency, seem to maintain a multi-channel state by very slow abandonment of old channel segments after avulsive formation of bypasses. Over long interavulsion periods, these anastomosing rivers are virtually static multi-channel systems.
