What are the characteristics of cardiac muscle compared to other types of muscles?
Understand the Problem
The image provides information about the types of muscles, specifically focusing on differences between cardiac muscle and other muscle types. It details various characteristics such as structure, blood supply, and control mechanisms.
Answer
Cardiac muscle has branched fibers, is uninucleated, features intercalated discs, rapid contractions, an abundant blood supply, and is involuntary.
Cardiac muscle is characterized by branched fibers, being uninucleated, bounded by plasmalemma, faint light and dark bands, the presence of intercalated discs, an abundant blood supply, rapid contractions, and being involuntary.
Answer for screen readers
Cardiac muscle is characterized by branched fibers, being uninucleated, bounded by plasmalemma, faint light and dark bands, the presence of intercalated discs, an abundant blood supply, rapid contractions, and being involuntary.
More Information
Cardiac muscles are unique due to their intercalated discs which aid in synchronized contraction and distribution of electrical impulses across the heart.
Tips
Common mistakes include confusing cardiac muscle with skeletal muscle. Remember, cardiac muscles have intercalated discs and are involuntary.
