Stringhalt
Stringhalt is a sudden flexion of one or both hind legs in the horse, most easily seen while the horse is walking or trotting. It is most evident when the horse is backing up slowly, turning on the affected leg, or suddenly frightened. It can involve one or both hind legs of the horse. It is a spasmodic contraction of the lateral extensor tendons of the hind legs. There are four forms of stringhalt: *Australian stringhalt: a flatweed ('' Hypochaeris radicata'') is the suspected cause *Pseudostringhalt: the apparent result of a painful condition in the affected leg *Unilateral stringhalt: cause unknown, but often relieved by section of the lateral extensor tendon *Bilateral stringhalt: in two out of two affected horses necropsied, abnormal thalamus Treatment varies. Australian stringhalt Australian stringhalt was described and differentiated from classical stringhalt in 1884. Australian stringhalt is differentiated from classical stringhalt by the severity, occurrence of outbreaks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypochaeris Radicata
''Hypochaeris radicata'' (sometimes spelled ''Hypochoeris radicata'') – also known as catsear, flatweed, cat's-ear, hairy cat's ear, or false dandelion – is a perennial, low-lying edible herb often found in lawns. The plant is native to Europe, but has also been introduced to the Americas, Japan, Australia, and New Zealand, where it can be an invasive weed. It is listed as a noxious weed in the northwestern U.S. state of Washington. Botany The leaves, which may grow up to eight inches (20 cm) long, are lobed and covered in coarse hairs, forming a low-lying rosette around a central taproot. Forked stems carry bright yellow flower heads, and when mature these form seeds attached to windborne "parachutes". All parts of the plant exude a milky sap when cut. ''Hypochaeris'' species are used as food plants by the larvae of some Lepidoptera species including the shark moth. Etymology and differences from dandelions Its name is derived from Greek ὑπό ...

Muscular System Of The Horse
Types of muscle There are 3 types of muscle, all found within the equine: * Skeletal muscle: Contraction of these muscles leads to the muscle pulling a tendon, which in turn pulls a bone. Moving a bone results in either flexing or extending a joint. Skeletal muscles are usually arranged in pairs so that they oppose each other (they are "antagonists" irror image, with one flexing the joint (a flexor muscle) and the other extending it (extensor muscle). Therefore, one muscle of the pair must be relaxed in order for the other muscle in the pair to contract and bend the joint properly. A muscle or muscles and its/their tendon(s) that operate together to cause flexion or extension of a joint are referred to respectively as a flexor unit and an extensor unit. * Smooth: muscle which makes up automatic systems (digestive system, for example) * Cardiac: involuntary muscle the keeps the heart pumping and able to carry round oxygen to the muscles. Build of skeletal muscle Skeletal muscle is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flexion
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatom ...

Euthanasia
Euthanasia (from el, εὐθανασία 'good death': εὖ, ''eu'' 'well, good' + θάνατος, ''thanatos'' 'death') is the practice of intentionally ending life to eliminate pain and suffering. Different countries have different euthanasia laws. The British House of Lords select committee on medical ethics defines euthanasia as "a deliberate intervention undertaken with the express intention of ending a life, to relieve intractable suffering". In the Netherlands and Belgium, euthanasia is understood as "termination of life by a doctor at the request of a patient". The Dutch law, however, does not use the term 'euthanasia' but includes the concept under the broader definition of "assisted suicide and termination of life on request". Euthanasia is categorized in different ways, which include voluntary, non-voluntary, or involuntary. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycotoxin
A mycotoxin (from the Greek μύκης , "fungus" and τοξίνη , "toxin") is a toxic secondary metabolite produced by organisms of kingdom Fungi and is capable of causing disease and death in both humans and other animals. The term 'mycotoxin' is usually reserved for the toxic chemical products produced by fungi that readily colonize crops. Examples of mycotoxins causing human and animal illness include aflatoxin, citrinin, fumonisins, ochratoxin A, patulin, trichothecenes, zearalenone, and ergot alkaloids such as ergotamine. One mold species may produce many different mycotoxins, and several species may produce the same mycotoxin. Production Most fungi are aerobic (use oxygen) and are found almost everywhere in extremely small quantities due to the diminute size of their spores. They consume organic matter wherever humidity and temperature are sufficient. Where conditions are right, fungi proliferate into colonies and mycotoxin levels become high. The reason for the product ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elymus Repens
''Elymus repens'', commonly known as couch grass, is a very common perennial species of grass native to most of Europe, Asia, the Arctic biome, and northwest Africa. It has been brought into other mild northern climates for forage or erosion control, but is often considered a weed. Other names include common couch, twitch, quick grass, quitch grass (also just quitch), dog grass, quackgrass, scutch grass, and witchgrass.Flora of NW Europe''Elytrigia repens''/ref>Flora of China''Elytrigia repens''/ref> Description It has creeping rhizomes which enable it to grow rapidly across grassland. It has flat, hairy leaves with upright flower spikes. The stems ( 'culms') grow to 40–150 cm tall; the leaves are linear, 15–40 cm long and 3–10 mm broad at the base of the plant, with leaves higher on the stems 2–8.5 mm broad. The flower spike is 10–30 cm long, with spikelets 1–2 cm long, 5–7 mm broad and 3 mm thick with three to eight floret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rumex Acetosella
''Rumex acetosella'', commonly known as red sorrel, sheep's sorrel, field sorrel and sour weed, is a species of flowering plant in the buckwheat family Polygonaceae. Native to Eurasia and the British Isles, the plant and its subspecies are common perennial weeds. It has green arrowhead-shaped leaves and red-tinted deeply ridged stems, and it sprouts from an aggressive and spreading rhizome. The flowers emerge from a tall, upright stem. Female flowers are maroon in color. Description ''Rumex acetosella'' is a perennial herb which spreads via rhizomes.

Hypochaeris Radicata Plant1 (14632148832)
''Hypochaeris'' is a genus of plants in the family Asteraceae. Many species are known as cat's ear. These are annual and perennial herbs generally bearing flower heads with yellow ray florets. These plants may resemble or be confused with dandelions and so some are called false dandelions. Estimates of the number of species range from about 50 up to about 100. Most species are native to South America, but some are found in Eurasia and North Africa. Etymology Its name is derived from Greek Greek may refer to: Greece Anything of, from, or related to Greece, a country in Southern Europe: *Greeks, an ethnic group. *Greek language, a branch of the Indo-European language family. **Proto-Greek language, the assumed last common ancestor ...

Australian Veterinary Journal
The Australian Veterinary Association (AVA) is a not-for-profit association representing more than 6000 Australian veterinarians working in private practice, government, industry, and academia. The AVA was mooted before the First World War but not founded until 1921. The nineteenth century predecessor organisation was the Australasian Veterinary Medical Association. Prominent veterinarians who have been members of the Australian Veterinary Association include Professor J.D. Stewart (who was the first AVA President), Ian Clunies Ross (former head of the CSIRO), and parasitologist Hugh Gordon. The AVA provides information resources, continuing education opportunities, publications, public education programs, and professional support. The AVA also lobbies government on a number of fronts. Special interest groups have existed within the AVA since the early 1960s. These include groups dedicated to equine medicine, cattle, practice management, avian health, sheep, conservation and ani ...

Phenytoin
Phenytoin (PHT), sold under the brand name Dilantin among others, is an anti-seizure medication. It is useful for the prevention of tonic-clonic seizures (also known as grand mal seizures) and focal seizures, but not absence seizures. The intravenous form, fosphenytoin, is used for status epilepticus that does not improve with benzodiazepines. It may also be used for certain heart arrhythmias or neuropathic pain. It can be taken intravenously or by mouth. The intravenous form generally begins working within 30 minutes and is effective for roughly 24 hours. Blood levels can be measured to determine the proper dose. Common side effects include nausea, stomach pain, loss of appetite, poor coordination, increased hair growth, and enlargement of the gums. Potentially serious side effects include sleepiness, self harm, liver problems, bone marrow suppression, low blood pressure, and toxic epidermal necrolysis. There is evidence that use during pregnancy results in abnormalities ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
