In cardiac muscle
a. an action potential spreads throughout the Z discs.
b. intercalated discs connect the muscle fibers together.
c. calcium enters the cell from storage chambers called intercalated discs.
d. potassium is released from the sarcoplasmic reticulum
Answer:
b. intercalated discs connect the muscle fibers together.
Explanation:
Intercalated discs are components of the muscles found in the heart(cardiac muscles).
Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.
Intercalated discs are made of up desmosomes and gap junctions.
Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.
<span>Answer is letter D which is “all eukaryotic cells”.
