B. T-tubules
C. intercalated discs
D. sarcomeres

Answer 1

Answer: the following are found in cardiac muscle except skeletal muscle. intercalated discs and gap junction. The correct option is C and E.

Step-by-step explanation:

There are three different type of muscles,

Smooth muscle

Skeletal muscle and

Cardiac muscle.

The cardiac muscle contains intercalated discs and gap junction which is absent in skeletal muscle.

Intercalated discs contain gap junctions and desmosomes. The gap junctions, which are protein-lined tunnels, allow direct transmission of the depolarizing current from cell to cell, across the chambers of the heart, so that the cells contract in unison.
