👉 Urethrobulbar refers to a pair of structures that connect the urethra and the bladder. These structures are located at the end of the penis, which is also known as the glans. The urethra is a tube-like structure that carries urine from the bladder into the urethral sphincter, a muscle in the urinary system responsible for controlling the flow of urine. The bladder, on the other hand, stores urine and helps regulate its volume.
