Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Triad is present in skeletal muscle.
Reason (R) : T tubule and terminal cisternae of sarcoplasmic reticulum form triad.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true and (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Remember the structural differences in muscle types:
- Skeletal muscle has triads (1 T-tubule + 2 terminal cisternae).
- Cardiac muscle has diads (1 T-tubule + 1 terminal cisterna).

Answer 1

The Correct Option is A
