Panosteitis
Panosteitis, sometimes shortened to pano among breeders, is an occasionally seen long bone condition in large breed dogs. It manifests with sudden, unexplained pain and lameness that may shift from leg to leg, usually between 5 and 14 months of age, earning the nickname "growing pains. " Signs such as fever, weight loss, anorexia, and lethargy can also be seen. The cause is unknown, but genetics, stress, infection, metabolism, or an autoimmune component may be factors. It has also been suggested that rapid growth and high-protein food are involved in the pathogenesis. Whole blood analysis may show an elevated white blood cell count; this finding lends support to the theory that panosteitis is due to an infection. Panosteitis is characterized histologically by an increase in activity of osteoblasts and fibroblasts in the periosteum, endosteum and bone marrow, resulting in fibrosis and the formation of connective tissue in the medullary cavity of the affected bone. Pain may be ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fever
Fever, also referred to as pyrexia, is defined as having a temperature above the normal range due to an increase in the body's temperature set point. There is not a single agreed-upon upper limit for normal temperature with sources using values between in humans. The increase in set point triggers increased muscle contractions and causes a feeling of cold or chills. This results in greater heat production and efforts to conserve heat. When the set point temperature returns to normal, a person feels hot, becomes flushed, and may begin to sweat. Rarely a fever may trigger a febrile seizure, with this being more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from non-serious to life-threatening. This includes viral, bacterial, and parasitic infections—such as influenza, the common cold, meningitis, urinary tract infections, appendicitis, Lassa, COVID-19, and malaria. Non-infectious cause ...

X-ray
X-rays (or rarely, ''X-radiation'') are a form of high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 and named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . X-ray wavelengths are shorter than those of ultraviolet rays and longer than those of gamma rays. There is no universally accepted, strict definition of the bounds of the X-ray band. Roughly, X-rays have a wavelength ranging from 10 nanometers to 10 picometers, corresponding to frequencies in the range of 30 petahertz to 30 exahertz ( to ) and photon energies in the range of 100 eV to 100 keV, respectively. X-rays can penetrate many solid substances such as construction materials and living tissue, so X-ray radiography is widely used in medi ...

Camel
A camel (from: la, camelus and grc-gre, κάμηλος (''kamēlos'') from Hebrew or Phoenician: גָמָל ''gāmāl''.) is an even-toed ungulate in the genus ''Camelus'' that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food ( milk and meat) and textiles (fiber and felt from hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel. The one-humped dromedary makes up 94% of the world's camel population, and the two-humped Bactrian camel makes up 6%. The Wild Bactrian camel is a separate species and is now critically endangered. The word ''camel'' is also used informally in a wider sense, where the more correct term is "camelid", to include all seven species of the family Camelidae: the true camels (the above three species), along with the "New World" camelids: the ...

Rottweiler
The Rottweiler (, ) is a breed of domestic dog, regarded as medium-to-large or large. The dogs were known in German as , meaning Rottweil butchers' dogs, because their main use was to herd livestock and pull carts laden with butchered meat to market. This continued until the mid-19th century when railways replaced droving. Although still used to herd stock in many parts of the world, Rottweilers are now also used as search and rescue dogs, guard dogs, and police dogs.Adolf Pienkoss, ''The Rottweiler'', 3rd ed., Borken, Germany: Internationale Föderation der Rottweilerfreunde, 2008. History According to the FCI Standard, the Rottweiler is considered to be one of the oldest surviving dog breeds. Its origin goes back to Roman times. These dogs were kept as herder or driving dogs. They marched over the Alps with the Roman legions, protecting the humans and driving their cattle. In the region of Rottweil, these dogs met and mixed with the native dogs in a natural crossi ...

Basset Hound
The Basset Hound is a short-legged breed of dog in the hound family. The Basset is a scent hound that was originally bred for the purpose of hunting hare. Their sense of smell and ability to ''ground-scent'' is second only to the Bloodhound.Hart, Ernest H. ''This Is the Basset Hound'', T.F.H. Books, 1974. Basset Hounds are one of six recognized " basset"-type breeds in France. The name ''Basset'' is derived from the French word ''bas'', meaning 'low', with the attenuating suffix ''-et''—together meaning 'rather low'. Basset Hounds are usually bicolours or tricolours of standard hound coloration. Description Appearance Bassets are large, short, solid and long, with curved sabre tails held high over their long backs. An adult dog weighs between . This breed, relative to its size, is heavier-boned than any other. This breed, like its ancestor the Bloodhound, has a hanging skin structure, which causes the face to tend to have a sad look; this, for many people, adds to the b ...

Golden Retriever
The Golden Retriever is a Scottish breed of retriever dog of medium size. It is characterised by a gentle and affectionate nature and a striking golden coat. It is commonly kept as a pet and is among the most frequently registered breeds in several Western countries. It is a frequent competitor in dog shows and obedience trials; it is also used as a gundog, and may be trained for use as a guide dog. The breed was created by Sir Dudley Marjoribanks at his Scottish estate Guisachan in the late nineteenth century. He cross-bred Flat-coated Retrievers with Tweed Water Spaniels, with some further infusions of Red Setter, Labrador Retriever and Bloodhound. The breed was recognised by the Kennel Club in 1913, and during the interwar period spread to many parts of the world. History The Golden Retriever was developed in Scotland in the nineteenth century by Sir Dudley Marjoribanks (later to become Baron Tweedmouth) from Flat-coated Retrievers judiciously crossed ...

German Shepherd Dog
The German Shepherd or Alsatian is a German breed of working dog of medium to large size. The breed was developed by Max von Stephanitz using various traditional German herding dogs from 1899. It was originally bred as a herding dog, for herding sheep. It has since been used in many other types of work, including disability assistance, search-and-rescue, police work, and warfare. It is commonly kept as a companion dog, and according to the Fédération Cynologique Internationale had the second-highest number of annual registrations in 2013. History During the 1890s, attempts were being made to standardise dog breeds. Dogs were being bred to preserve traits that assisted in their job of herding sheep and protecting their flocks from predators. In Germany this was practised within local communities, where shepherds selected and bred dogs. It was recognised that the breed had the necessary skills for herding sheep, such as intelligence, speed, strength and keen senses of ...

Nutrient Foramen
All bones possess larger or smaller foramina (openings) for the entrance of blood-vessels; these are known as the nutrient foramina, and are particularly large in the shafts of the larger long bones, where they lead into a nutrient canal, which extends into the medullary cavity. The nutrient canal(foramen)is directed away from the growing end of bone. The growing ends of bones in upper limb are upper end of humerus and lower ends of radius and ulna. In lower limb, the lower end of femur and upper end of tibia are the growing ends. The nutrient arteries along with veins pass through this canal. A nutrient canal is found in long bones, in the mandible In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bon ..., and in dental alveoli. In long bones the nutrient canal is found in the shaft. Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humerus
The humerus (; ) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes (trochlea & capitulum), and 3 fossae (radial fossa, coronoid fossa, and olecranon fossa). As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons. Etymology The word "humerus" is derived from la, humerus, umerus meaning upper arm, shoulder, and is linguistically related to Gothic ''ams'' shoulder and Greek ''ōmos''.

Histology
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Although one may divide microscopic anatomy into ''organology'', the study of organs, ''histology'', the study of tissues, and '' cytology'', the study of cells, modern usage places all of these topics under the field of histology. In medicine, histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. In the field of paleontology, the term paleohistology refers to the histology of fossil organisms. Biological tissues Animal tissue classification There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these four principal tissue type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
