ANATOMY

Detailed explanation-1: -Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside.

Detailed explanation-2: -Bowman’s capsule is known by other names, including the glomerular capsule, the Malpighian capsule and the renal corpuscular capsule. Bowman’s space also has other names, including glomerular capsule space, filtration space and urinary space.

Detailed explanation-3: -The renal capsule is surrounded by the renal fascia. Overlying the renal fascia and between this and the transverse fascia is a region of pararenal fat. The kidney capsule surrounds both kidneys, and is labelled at the bottom right.

Detailed explanation-4: -The kidney capsule consists of a layer of stromal cells surrounded by a sheet of connective tissue and is of major importance during kidney development and adult kidney homeostasis. During kidney development 3 different locations of stromal cells can be observed; capsular, cortical and medullary stromal cells.

Detailed explanation-5: -A special reticular basket-like system of connective tissue strips (called connective tissue skeleton-CTS) was found between the cortex and medulla in the kidney of various mammals. It enlarges the wall of the renal calyx (or pelvis) into the parenchyma. The main component of this system is collagen.
