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 kidneys are bean-shaped with the convex side of each organ located laterally and the concave side medial. The indentation on the concave side of the kidney, known as the renal hilus, provides a space for the renal artery, renal vein, and ureter to enter the kidney.he kidneys are a pair of organs found along the posterior muscular wall of the abdominal cavity. The left kidney is located slightly more superior than the right kidney due to the larger size of the liver on the right side of the body.
