PREVIOUS AND NEXT TERMS--------------------------------------
Recessive gene
A gene that is inferior to another gene that controls the same trait (the dominant gene). The inferior gene does not get expressed in the presence of a dominant gene.
Rectum
An 8-inch chamber connected to the large intestine that receives solid waste (feces) from the descending colon to be expelled from the body. The rectum connects the colon to the anus. It is the rectum's job to receive stool from the colon, to let the person know that there is stool to be evacuated, and to hold the stool until evacuation happens.
Rheumatism
A general disease characterized by painful, often multiple, local inflammations, usually affecting the joints and muscles, but also extending sometimes to the deeper organs, as the heart.
Retinitis Pigmentosa (RP)
A hereditary condition resulting in degeneration of the retina; causes a narrowing of the field of vision. The visual field loss often begins as a donut like ring in mid-periphery. As it progresses both centrally and peripherally, the resultant tunnel vision begins to affect the patient’s activities, driving and mobility.
Rheumatoid arthritis
Rheumatoid arthritis is a chronic disease that is of unknown cause and is characterized by pain, stiffness, inflammation, swelling and sometimes destruction of joints.
Rigidity
Rickets
A disorder of childhood characterised by defective bone and mineralisation, where characteristic lower limb bowing or bending occurs. Other outward signs of rickets can be the so-called rachitic rosary on the ribs, and thickened wrists, as well as bossing of the forehead.
Rheumatic Fever
A serious inflammatory condition which follows Streptococcal pharyngitis. Acute rheumatic fever can destroy the heart valves or leave them vulnerable to scarring, thickening, calcification, and fusion of the leaflets later in life.
Ribosome
A cytoplasmic cellular structure, composed of ribonucleic acid and protein, that functions in the synthesis of protein. Ribosomes interact with messenger RNA and transfer RNA to join together amino acid units into a polypeptide chain according to the sequence determined by the genetic code.
Radioisotope scan
Uses radioactive substances introduced into the body to create an image of the functioning adrenal gland.
Risk factors
Traits that make it more likely that a person will develop an illness.
