Ruminant

Ruminant A suborder of the order Artiodactyla whose members have the distinguishing feature of a four-chambered stomach. Horns or antlers are usually present, at least in males.
RELATED TERMS--------------------------------------
Stomach
The organ between the esophagus and the small intestine. The stomach is where digestion of protein begins.
SIMILAR TERMS--------------------------------------
Ruminantia
A suborder of the order Artiodactyla whose members have the distinguishing feature of a four-chambered stomach. Horns or antlers are usually present, at least in males.
PREVIOUS AND NEXT TERMS--------------------------------------
Retrobulbar neuritis
An inflammation of the optic nerve. It causes a loss in vision. It is sometimes indicative of a neurological disease.
Rod cone dystrophy
A number of retina diseases in which the rod photoreceptors first start to degenerate followed by the cone photoreceptors. Other parts of the retina and RPE are also adversely affected. Symptoms include loss of side vision and night blindness followed by the loss of central vision. RP is the most common form of rod-cone degeneration. Some forms occur at birth while other forms may start much later in life. Generally very poor prognosis.
Rods
The rods are the visual cells of the retina that are important for night vision and peripheral vision. The rods are the first affected in rod-cone degenerations such as RP.
Ranidae
The family of true frogs of the order Anura. The family occurs worldwide except in Antarctica.
Ranide
Veterinary anthelmintic for grazing animals; used to treat fluke, hookworm and other infestations.
Ruminant
Ruminantia
A suborder of the order Artiodactyla whose members have the distinguishing feature of a four-chambered stomach. Horns or antlers are usually present, at least in males.
Rabies
An acute infectious disease of the central nervous system affecting almost all mammals, including humans. It is caused by a rhabdovirus and usually spread by contamination with virus-laden saliva of bites inflicted by rabid animals. Important animal vectors include the dog, cat, vampire bat, mongoose, skunk, wolf, raccoon, and fox.
Repetitive strain injury
Harmful and painful condition caused by overuse or overexertion of some part of the musculoskeletal system, often resulting from work-related physical activities. It is characterized by inflammation, pain, or dysfunction of the involved joints, bones, ligaments, and nerves.
Restless legs
A disorder characterized by aching or burning sensations in the lower and rarely the upper extremities that occur prior to sleep or may awaken the patient from sleep. Complying with an irresistible urge to move the affected limbs brings temporary relief. Sleep may become disrupted, resulting in excessive daytime hypersomnolence. This condition may be associated with uremia; diabetes; and rheumatoid arthritis. Restless Legs Syndrome differs from nocturnal myoclonus syndrome in that in the lattercondition the individual does not report adverse sensory stimuli and it is primarly a sleep-associated movement disorder.
Rosacea
An acneiform eruption occurring mostly in middle-aged adults and appearing generally on the forehead, cheeks, nose, and chin. Three types are recognized: granulomatous, glandular hyperplastic with rhinophyma, and ocular.
