Cardiac Muscle Tissue Anatomy & Physiology Review Lecture

What are Fascia Adherens?

Fascia adherens are connections that stick to the actin filaments in cardiac muscle cells. They help keep the cells strong and allow them to contract together at the same time.

What do desmosomes do in cardiac muscle

Desmosomes help keep heart muscle cells together by connecting them firmly. This prevents the cells from pulling apart when the heart contracts

What do intercalated disks consist of?

Intercalated disks consist of specialized connections between cardiac muscle cells that include fascia adherens, desmosomes (provide mechanical strength), and gap junctions. They facilitate communication and coordination of contractions between the cells.

What do gap junctions do in cardiac muscle cells?

Gap junctions allow for direct communication between cardiac muscle cells by providing a passage for ions and small molecules. This enables the rapid transmission of electrical signals, ensuring coordinated contraction of the heart.

What are the role of intercalated disks?

Intercalated disks play a crucial role in connecting cardiac muscle cells, giving structural support and facilitating/making electrical communication for synchronized(in synch) contractions.
