Yes, that is true.

No. It's the only type of muscle tissue that doesn't have gap junctions. Cardiac and smooth muscles have gap junctions.
Gap junctions. Gap junctions are connecting channels made of proteins that permit the movement of ions or water between two adjacent cells. They are commonly found in cardiac and smooth muscle cells.Read more: what-are-gap-junctions
Cardiac muscle tissue likely contains large amounts of gap junctions. These junctions facilitate direct communication between adjacent cardiac muscle cells, allowing for coordinated contraction of the heart. Gap junctions enable the rapid spread of electrical signals, essential for maintaining a synchronized heartbeat. Additionally, some smooth muscle tissues may also have significant gap junctions for similar reasons.
All four tissue types—epithelial, connective, muscle, and nervous tissue—can have intercellular junctions, but they are most prominent in epithelial and cardiac muscle tissues. Epithelial tissues utilize tight junctions, desmosomes, and gap junctions to maintain structural integrity and facilitate communication. Cardiac muscle tissue also features intercalated discs, which contain gap junctions and desmosomes to synchronize heart contractions. In contrast, connective and nervous tissues typically have fewer intercellular junctions, focusing more on structural support and signal transmission, respectively.

You would expect to find numerous gap junctions in cardiac muscle tissue and certain types of smooth muscle tissue. In cardiac muscle, gap junctions facilitate the rapid propagation of electrical signals necessary for synchronized heart contractions. In smooth muscle, they enable coordinated contractions across muscle fibers, allowing for effective movement of substances through hollow organs. Gap junctions play a crucial role in cell-to-cell communication in these tissues.
No. Smooth muscle and cardiac muscle are two different types of muscle tissue. Smooth muscle does not have striations (or stripes) and is located in the organs. Cardiac muscle is striated (has stripes) and fits together with gap junctions that allow for quick passage.
The myocardial cells are connected through tight junctions and gap junctions between the cell membranes of adjacent cells. The myocardium as a whole is covered by the pericardium on the outside and the endocardium on the inside.
Cardiac muscle is network of branched fibers (cells) connected by gap junctions called intercalated disks.
The type of muscle tissue that features self-excitable pacemaker cells, gap junctions, and a limited sarcoplasmic reticulum is cardiac muscle tissue. Cardiac muscle is involuntary and has specialized cells that generate electrical impulses, allowing for coordinated contractions. The presence of gap junctions facilitates communication between cells, ensuring synchronized heartbeats.
