What best describes the cells of unitary smooth muscle?

Smooth muscle is the involuntarily controlled muscle. In unitary smooth muscle, the cells are connected by gap junctions and are controlled by the autonomic nervous system and hormones.


What type muscle cells are arranged in sheets or layers with adjacent muscle cells electrically connected by gap junctions and mechanically connected by dense bodies?

Smooth muscle cells are arranged in sheets or layers with adjacent cells connected by gap junctions and dense bodies. This allows for coordinated contraction and relaxation of muscle tissue.


Are cardia muscle cells electrically connected by gap junctions and behave as a single unit?

Because cardiac muscle cells are electrically connected by gap junctions, the entire myocardium behaves like a single unit, a functional syncytium.


Adult cell types you might expect to have gap junctions include?

Neurons, cardiac muscle cells, and smooth muscle cells are adult cell types that typically have gap junctions. Gap junctions allow for direct electrical and chemical communication between neighboring cells, facilitating coordination and synchronization in tissue function.


How are single unit and multi-unit smooth muscle cells alike and different?

Single-unit smooth muscle are coupled with one another through gap junctions and they work as a single unit (wave-like). I believe this is myogenic. Multi-unit smooth muscle on the other hand, act indepently (not wave-like) and are neurogenic (stimulated by neurons). These are not coupled by jap junctions like the single-unit smooth muscle are.


What attaches cardiac muscle fibers together?

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.


What structural component of cardiac muscle cell allows for electrical current to flow from cell to cell?

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


How cells are connected in human body?

Cells in the human body are connected through a network of structures called intercellular junctions. These junctions allow cells to communicate, adhere to one another, and exchange molecules. There are different types of intercellular junctions, such as tight junctions, gap junctions, and desmosomes, that play specific roles in maintaining tissue structure and function.


Do adjacent cells share common cell wall?

Yes, adjacent plant cells are connected by structures called plasmodesmata that pass through the cell wall, allowing for communication and transport of materials between the cells. In animal cells, adjacent cells are connected by intercellular junctions like tight junctions, adherens junctions, and gap junctions.


What are the two types of cellular junctions found at intercalated disc?

Cardiac muscle is network of branched fibers (cells) connected by gap junctions called intercalated disks.


What is a functional syncytium?

Cardiac muscle cells are mechanically, chemically, and electrically connected to one another, thus, the entire tissue resembles a single, enormous muscle cell. For this reason, cardiac muscle has been called a functional syncytium. This is also true of smooth muscle.


Which type of muscles contain spindle shaped cells?

Skeletal muscle tissue has cylindrical cells. Due to the cells in the skeletal muscle, the muscle can now allow movement to the bones in the body.
