The results revealed that the kidney was enclosed by thin capsule , consist of smooth muscle fibers and fibrous tissue . The lobes of the kidney contain medulla and cortex , the quantity of the cortical tissue is more than the medullary tissue , The large area of the cortex surrounded the small islets of the medulla .The cortex and medulla do not constitute continuous internal and external layer . There are two types of nephron , the first is the cortical nephron which represented the large portion of the cortex that devoided from henles loop and limited by cortical zone from the kidney lobule , this nephron was similar to reptile nephron .While the second type ( medullary nephron) which contains the henles loop that penetrate the medullary zone and resemble to mammalian nephron. | ||
