HORSES |
|
The horse (Equus caballus or Equus ferus caballus) is a sizeable ungulate mammal, one of ten modern species of the genus Equus. Horses have long been one of the most economically important domesticated animals, and have played an important role in the transport of people and cargo for thousands of years. Most notably, horses can be ridden by a person perched on a saddle attached to the animal, and are also widely harnessed to pull objects like wheeled vehicles or plows. In some human cultures, horses are also widely used as a source of food. Though isolated domestication may have occurred as early as 4500 BC, clear evidence of widespread use by humans dates to no earlier than 2000 BC, as evidenced by the Sintashta chariot burials, thus firmly establishing the domestication of the horse.

PRESSURE SORE |
|
Bedsores, also called pressure sores or pressure ulcers, are ulcers (sores) caused by prolonged pressure or rubbing on vulnerable areas of the body, such as bony or cartilaginous areas that are prone to moisture and friction. Decubitus ulcers are pressure ulcers that occur when the patient lies on his or her back for long periods (Wilhelmi and Neumeister, 2005). Examples of areas vulnerable to pressure ulcers include the hips, ankles, heels, elbows, ears, and pressure points on the lower back (near the tail bone, sacrum, or iliac crest). Pressure sores are also caused by prolonged sitting, or certain patterns of sitting behaviour
