Assertion: In cardiac muscle tissue, the communication junctions (intercalated discs) at some fusion points allow the cells to contract as a unit.
Reason: When one cell of cardiac muscle tissue recieves a signal to contract, its neighbours are also stimulated to contract.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
A
In cardiac muscle tissues, the communication junctions (intercalated disc) at some fusion points allow the cells to contract as a unit because when one cell of cardic muscle tissue receives a signal to contract, its neighbours are also stimulated to contract.
