Which term refers to the membranous tube extending from the urinary bladder to the exterior?

  1. Unsteady

  2. Urethral

  3. Urinary tract

  4. Urinary elimination

The correct answer is: Urethral

The term that refers to the membranous tube extending from the urinary bladder to the exterior is "urethral." The urethra is a crucial part of the urinary system, serving as the conduit through which urine is expelled from the body. Understanding this term is essential for those training in CNA roles, as it helps in accurately describing patient anatomy and understanding urinary functions. The other terms listed relate to broader concepts within the urinary system. "Unsteady" does not pertain to any anatomical structure. "Urinary tract" refers to the entire system including the kidneys, ureters, bladder, and urethra, rather than just the tube. "Urinary elimination" describes the process of expelling urine but does not refer to the specific structure itself. Thus, the selection of "urethral" accurately identifies the specific anatomical feature in question.
