Given below are two statements.
Statement I - Nervous tissue is without lymphatic vessels.
Statement II - Nervous tissue is endodermal in origin.
In light of above statements, choose the most appropriate correct answer from the option 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 and statement II is incorrect.
• D. Statement I is incorrect and statement II is correct.

Hint:

Germ layer trick: Ectoderm $\rightarrow$ Skin & Nervous system
Mesoderm $\rightarrow$ Muscles & Blood
Endoderm $\rightarrow$ Internal organs

Answer 1

The Correct Option is C

Concept: Nervous tissue is a specialized tissue responsible for receiving and transmitting impulses. It has unique structural and developmental characteristics.
• Nervous tissue lacks lymphatic vessels.
• It originates from the ectoderm during embryonic development.

Step 1: Analyze Statement I.
Nervous tissue (especially brain tissue) does not have conventional lymphatic vessels. Hence, Statement I is correct.

Step 2: Analyze Statement II.
Nervous tissue develops from the ectoderm (outer germ layer), not from the endoderm. Hence, Statement II is incorrect.

Step 3: Conclusion.
Statement I is correct, while Statement II is incorrect. Final Answer: Option (C)
