Question

Assertion (A) : Aponeurosis is a type of connective tissue.
Reason (R) : Aponeurosis is a chord-like structure that may extend beyond the muscle.
Identify the correct option from the following

• (A) and (R) are true. (R) is correct explanation for (A).
• (A) and (R) are true. But (R) is not the correct explanation for (A).
• (A) is true, but (R) is false.
• (A) is false, but (R) is true.

Hint:

Distinguish between different types of connective tissues that attach muscles to bones: tendons are typically cord-like, while aponeuroses are flat, sheet-like structures. Both are forms of dense regular connective tissue.

Answer 1

The Correct Option is C

Step 1: Analyze Assertion (A).
Assertion (A) states: "Aponeurosis is a type of connective tissue." Aponeurosis is a broad, flattened, sheet-like tendon that serves to attach muscles to bones, fascia, or other muscles. Structurally, tendons are composed of dense regular connective tissue, primarily collagen fibers. Therefore, aponeurosis, being a type of tendon (a modified form of a tendon), is indeed a type of connective tissue. This statement is True. Step 2: Analyze Reason (R).
Reason (R) states: "Aponeurosis is a chord-like structure that may extend beyond the muscle."
A "chord-like structure" typically refers to something resembling a cord or string, which is characteristic of tendons (like the Achilles tendon). However, an aponeurosis is distinct from a cord-like tendon. It is a broad, flat sheet. While it does attach muscles and may extend from them, describing it as "chord-like" is incorrect. Its defining characteristic is its flat, sheet-like appearance, differentiating it from typical cord-like tendons. This statement is False. Step 3: Evaluate the options based on the truthfulness of A and R. \begin{itemize} \item Option (1): (A) and (R) are true. (R) is correct explanation for (A). (Incorrect, as R is false) \item Option (2): (A) and (R) are true. But (R) is not the correct explanation for (A). (Incorrect, as R is false) \item Option (3): (A) is true, but (R) is false. (This matches our analysis) \item Option (4): (A) is false, but (R) is true. (Incorrect, as A is true and R is false) \end{itemize} Step 4: Conclude the correct option.
Based on the analysis, Assertion (A) is true, and Reason (R) is false. The final answer is $\boxed{\text{(A) is true, but (R) is false}}$.
