A glomus is a glomerulus that spans more than one body segment. It is the vascularized filter of the pronephric kidney. Blood is filtered through the glomus and the filtrate deposited into the coelom early in development, or the nephrocoel later in development. The glomus contains podocytes with well developed foot processes that are anatomically indistinguishable from the podocytes of adult glomeruli. The two glomera are linked via a narrow bridge called the glomeral nexus. renal corpuscle Properly called a glomus as it extends over multiple body segments. glomerulus glomera xenopus_anatomy XAO:0000318 UBERON:0004739 pronephric kidney multi-tissue structure NF stage 29 and 30 NF stage 55
