Describe the structure of cardiac muscles in 2 points. Pls give no links.

Structure of Cardiac Muscles:
  • They are only involuntary muscles.
  • Their structure is in-between the striated and non-striated muscles.
  • They are uninucleatewd and branched. Branches are united and intercalated disc.
Hope it will help you....
See ya...

1. ​Although it is striated, cardiac muscle differs from skeletal muscle in that it is highly branched with cells connected by overlapping projections of the sarcolemma called intercalated discs. These discs contain desmosomes and gap junctions.

2.
Cardiac muscle is in some ways similar to skeletal and smooth muscle. For example, all three contract when a rise in calcium inside the muscle cell allows interaction between actin and myosin filaments. However, cardiac muscle has aunique
 structure, and differs in the way that contraction is initiated and regulated.
