Zenker's Diverticulum
A Zenker's diverticulum, also pharyngeal pouch, is a diverticulum of the mucosa of the human pharynx, just above the cricopharyngeal muscle (i.e. above the upper sphincter of the esophagus). It is a pseudo diverticulum (not involving all layers of the esophageal wall). It was named in 1877 after German pathologist Friedrich Albert von Zenker. Signs and symptoms In simple words, when there is excessive pressure within the lower pharynx, the weakest portion of the pharyngeal wall balloons out, forming a diverticulum which may reach several centimetres in diameter. More precisely, while traction and pulsion mechanisms have long been deemed the main factors promoting development of a Zenker's diverticulum, current consensus considers occlusive mechanisms to be most important: uncoordinated swallowing, impaired relaxation and spasm of the cricopharyngeus muscle lead to an increase in pressure within the distal pharynx, so that its wall herniates through the point of least resistanc ...

Friedrich Albert Von Zenker
Friedrich Albert von Zenker (13 March 1825 – 13 June 1898) was a German pathologist and physician, celebrated for his discovery of trichinosis. He was born in Dresden, and was educated in Leipzig and Heidelberg. While in Leipzig, he worked for a while as an assistant to Justus Radius at the St. Georg Hospital. Attached to the city hospital of Dresden in 1851, he added, in 1855, the duties of professor of pathological anatomy and general pathology in the surgico-medical academy of that city. In 1862 he became professor of pathological anatomy and pharmacology at Erlangen. Three years afterwards he assumed with Hugo Wilhelm von Ziemssen the editorship of the "''Deutsches Archiv für klinische Medizin''". In 1895 he retired from active service. Zenker's diverticulum, a false pathological diverticulum of the posterior pharyngeal wall, through the thyropharyngeus and cricopharyngeus parts of the inferior constrictor muscle, is named after him. His important discovery of the dan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenker's Degeneration
Zenker's degeneration is a severe glassy or waxy hyaline degeneration or necrosis of skeletal muscles in acute infectious diseases; a prototype of coagulative necrosis. The condition was named by Friedrich Albert von Zenker. It is a hyaline degeneration of skeletal muscles such as rectus abdominis and diaphragm Diaphragm may refer to: Anatomy * Thoracic diaphragm, a thin sheet of muscle between the thorax and the abdomen * Pelvic diaphragm or pelvic floor, a pelvic structure * Urogenital diaphragm or triangular ligament, a pelvic structure Other * Diap ..., and occurs in severe toxaemia as typhoid fever. It is also seen in electrical burns. Grossly the muscles appear pale and friable; microscopically, the muscle fibres are swollen, have a loss of cross striations, and show a hyaline appearance. Rupture and small hemorrhage may complicate the lesion. Coagulative necrosis occurs here. References Muscular disorders {{muscle-stub ...

Zenker's Fixative
Zenker's fixative is a rapid-acting fixative for animal tissues. It is employed to prepare specimens of animal or vegetable tissues for microscopic study. It provides excellent fixation of nuclear chromatin, connective tissue fibers and some cytoplasmic features, but does not preserve delicate cytoplasmic organelles such as mitochondria. Helly's fixative is preferable for traditional dye staining of mitochondria. Zenker's fixative permeabilises the plasma, but not the nuclear membrane. It can therefore be used to selectively stain mitotic cells (where the nuclear membrane has dissolved) with antibodies against chromatin Zenker's fixative contains mercuric chloride ("corrosive sublimate"), potassium dichromate, sodium sulfate, water, and acetic acid. Fixatives containing mercuric chloride or potassium dichromate are toxic, making disposal as hazardous waste costly. Mercuric chloride can be replaced with the same weight of less toxic zinc chloride, but the resulting "zinc-Zenk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenker's Paralysis
Peroneal nerve paralysis is a paralysis on common fibular nerve that affects patient’s ability to lift the foot at the ankle. The condition was named after Friedrich Albert von Zenker. Peroneal nerve paralysis usually leads to neuromuscular disorder, peroneal nerve injury, or foot drop which can be symptoms of more serious disorders such as nerve compression. The origin of peroneal nerve palsy has been reported to be associated with musculoskeletal injury or isolated nerve traction and compression. Also it has been reported to be mass lesions and metabolic syndromes. Peroneal nerve is most commonly interrupted at the knee and possibly at the joint of hip and ankle. Most studies reported that about 30% of peroneal nerve palsy is followed from knee dislocations. Peroneal nerve injury occurs when the knee is exposed to various stress. It occurs when the posterolateral corner structure of knee is injured. Relatively tethered location around fibular head, tenuous vascular supply an ...

Christian Zenker
Christians () are people who follow or adhere to Christianity, a monotheistic Abrahamic religion based on the life and teachings of Jesus Christ. The words ''Christ'' and ''Christian'' derive from the Koine Greek title ''Christós'' (Χριστός), a translation of the Biblical Hebrew term ''mashiach'' (מָשִׁיחַ) (usually rendered as ''messiah'' in English). While there are diverse interpretations of Christianity which sometimes conflict, they are united in believing that Jesus has a unique significance. The term ''Christian'' used as an adjective is descriptive of anything associated with Christianity or Christian churches, or in a proverbial sense "all that is noble, and good, and Christ-like." It does not have a meaning of 'of Christ' or 'related or pertaining to Christ'. According to a 2011 Pew Research Center survey, there were 2.2 billion Christians around the world in 2010, up from about 600 million in 1910. Today, about 37% of all Christians live in the Ameri ...
