Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
It occurs in humans [1] and cats, more frequently occurring in dogs. It was first described in dogs by Griffin and colleagues in 1979. [2] [3] DLE is one form of cutaneous lupus erythematosus (CLE). DLE occurs in dogs in two forms: a classical facial predominant form or generalized with other areas of the body affected.
The amount of interstitial fluid varies from about 50% of the tissue weight in skin to about 10% in skeletal muscle. [2] Interstitial fluid pressure is variable, ranging from -1 to -4 mmHg in tissues like the skin, intestine and lungs to 21 to 24 mmHg in the liver, kidney and myocardium. Generally, increasing interstitial volume is associated ...
Histiocytic diseases in dogs are a group of diseases in dogs which may involve the skin, and which can be difficult to differentiate from granulomatous, reactive inflammatory or lymphoproliferative diseases. The clinical presentation and behaviour as well as response to therapy vary greatly among the syndromes.
In crystallography, interstitial sites, holes or voids are the empty space that exists between the packing of atoms (spheres) in the crystal structure. [ citation needed ] The holes are easy to see if you try to pack circles together; no matter how close you get them or how you arrange them, you will have empty space in between.
[10] [11] No other interstitial cell within the testes has a nucleus or cytoplasm with these characteristics, making identification relatively easy. While any age is susceptible to a Leydig cell tumour, Leydig cell tumours are more common in people aged 5 to 10 and 30 to 35. [12] A Leydig cell tumour in a child usually causes precocious puberty ...
Knee joint of dog. Piece showing knee joint of dog. An untreated hygroma can develop into a large swelling that stresses the surrounding skin and becomes an open wound with the possibility of infection that is much more difficult to treat. In most cases, a hygroma is a single occurrence for an animal, but other individuals will have repeated ...
IPF has been recognized in several breeds of both dogs and cats, [77] and has been best characterized in West Highland White Terriers. [78] Veterinary patients with the condition share many of the same clinical signs as their human counterparts, including progressive exercise intolerance, increased respiratory rate, and eventual respiratory ...
