Final answer:
The cup-shaped top of the nephron that surrounds the glomerulus is the Bowman's capsule.
Step-by-step explanation:
The cup-shaped top of the nephron that surrounds the glomerulus is the Bowman's capsule. The nephron, which is the functional unit of the kidney, consists of three parts: the renal corpuscle, the renal tubule, and the associated capillary network originating from the cortical radiate arteries. The renal corpuscle includes the glomerulus, a network of capillaries, and the Bowman's capsule, a cup-shaped chamber that surrounds the glomerulus.
