Short notes on the structure of loop of Henle

The proximal convoluted tubule takes a straight course down into the me­dulla region. This descending limb is called the loop of Henle. This loop of Henle is divided into three segments namely:

a) Thick descending segment which is the straight portion of the proximal convoluted tubule.

b) A thin segment which takes a direct radial course in the medulla. This segment takes a sharp hairpin bend extending past the tip of the Henle’s loop.

c) A thick ascending segment. This is a straight radial tubule. In this region the squamous epithelial cells suddenly change into cuboidal epi­thelial cells. This segment is relatively impermiable to salts and water.
