Nicotine stomatitis is generally a reversible lesion once the irritant is removed. The prognosis for nicotinic stomatitis is excellent. Although nicotine stomatitis is caused by smoking tobacco products, it is generally not associated with dysplastic or malignant changes.
There are two types of nephrons, distinguished by their location in the kidney. Cortical nephrons are located in the renal cortex on the outside of the organ, while juxtamedullary nephrons are located deeper in the kidney, in the renal medulla. Each nephron is made up of a renal corpuscle and a renal tubule.The renal corpuscle provides the initial filtering component, while the renal tubule is responsible for reabsorption. The corpuscle is composed of the glomerulus and Bowman's capsule.he nephron is the basic functional and structural unit of the kidney, and each human kidney contains from 800,000 to one million of these units.
There are two parts of a kidney nephron: the renal corpuscle, and the renal tubule. (1) Renal Corpuscle. The renal corpuscle is the part of the kidney nephron in which blood plasma is filtered.2) Renal Tubule. The renal tubule is the part of the kidney nephron into which the glomerular filtrate passes after it has reached the Bowman's capsule. The first part of the renal tubule is called the proximal convoluted tubule (PCT) , which is shown on the right-hand side of the diagram above.
