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.
The functional unit of the kidney is the nephron. Each adult kidney contains around 1â1.5 million nephrons. The basic structure of the nephron is shown in Figure 1. There are two types of nephron, the cortical and the juxtamedullary.he loop of Henle. The loop of Henle is the portion of the kidney that creates the conditions by which the kidney can form concentrated urine (i.e. urine with an osmolality greater than plasma) later on in the nephron.
