WebSingle-unit smooth muscle is found in the walls of hollow organs; multiunit smooth muscle is found in airways to the lungs and large arteries. Single-unit smooth muscle cells contract synchronously, they are coupled by gap junctions, and they exhibit spontaneous action potential. Web21 feb. 2024 · The multi-unit smooth cells are independent from each other and therefore need to be innervated individually allowing a more precise muscle control. They are found, among others, in the iris and hair erector muscles. Test your knowledge and consolidate what you've learned about the smooth musculature with this quiz: Summary
WebSmooth muscle is involuntary and non-striated. It can be divided into single-unit cells and multiunit smooth muscle tissue. Thus, the classification of fibers in skeletal muscle is representative of the different functions and processes that typically occur in the muscle and is not related to cardiac or smooth muscle tissue.

Smooth muscle differs from skeletal muscle in a …
WebThe multiunit smooth muscle fibers act indepen-dently. Similar to skeletal muscle fiber, each muscle fiber is innervated, with few gap junctions between adjacent cells. Therefore, each fiber must be stimu-lated separately to produce contraction. These fibers are found in the walls of large arteries, bronchioles, arrector pili muscle attached to ...
