Question

Given below are two statements:
Statement (I): Between the urinary bladder and the urethra, there are two sphincters, namely internal and external sphincters.
Statement (II): Of these, the external sphincter is made up of smooth muscles and dysfunction of the same can lead to kidney infection.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

The external sphincter is voluntary and made of skeletal muscle, not smooth muscle.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
The opening of the urinary bladder into the urethra is guarded by two sphincters.

Step 2: Statement (I)
There is an internal sphincter and an external sphincter, so Statement (I) is correct.

Step 3: Statement (II)
The internal sphincter is smooth (involuntary) muscle. The external sphincter is skeletal (voluntary) muscle, which lets us hold urine consciously.
Its weakness causes incontinence, not kidney infection, so Statement (II) is incorrect.

Step 4: Conclusion
Statement (I) is correct and Statement (II) is incorrect.

Final Answer:
Statement (I) is correct but Statement (II) is incorrect. \[ \boxed{\text{(C) }\text{Statement (I) is correct but Statement (II) is incorrect.}} \]
