Question

Do intercalated discs and striations suggest the presence of skeletal muscle?

Answer 1

No.

Explanation:

Cardiac muscle and skeletal muscle both have striations due to their structure, but intercalated discs are only found in the cardiac muscle. It has a lot of " gap " junctions, so the heart functions as a whole ( the gap junctions help spread the depolarization in the cardiac muscle, as the citoplasm of the cardiac cells are in contact.

So, definitely, presence of intercalated discs means were talking about the cardiac muscle.
