Question

Given below are two statements:
Statement (I): Cortical nephrons have shorter loop of Henle which extend very little in medulla.
Statement (II): Juxtamedullary nephrons have longer loop of Henle that runs deep into medulla.
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:

Cortical nephrons have short loops, while juxtamedullary nephrons have long loops reaching deep into the medulla.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
Nephrons are of two types, cortical and juxtamedullary.

Step 2: Check Statement (I)
Cortical nephrons lie mostly in the cortex and have a short loop of Henle extending very little into the medulla. This is correct.

Step 3: Check Statement (II)
Juxtamedullary nephrons lie near the cortex and medulla border and have long loops going deep into the medulla, which helps form concentrated urine. This is correct.

Step 4: Conclusion
Both statements are correct.

Final Answer:
Both statements are correct. \[ \boxed{\text{(A) }\text{Both Statement (I) and Statement (II) are correct.}} \]
