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.

Smooth muscle is characterized by?
The smooth muscle is an involuntary, non-striated muscle. It is divided into two sub-groups: the single-unit and multiunit smooth muscle.
Where is smooth muscle and what are its functions?
Smooth muscles are an involuntary non-striated muscles. It is divided into two sub-groups; the Single unit (unitary) and multiunit smooth muscle Hope this helps! :)
Which are the two major types of smooth muscle?
multiunit ans visceral
What kind of muscle tissue is piloerector muscle made of?
It's made out smooth muscle, of the multiunit variety, like the iris.
What is Non-striated involuntary muscle type?
its Smooth muscle is an involuntary non-striated muscle, so-called because it has no sarcomeres and therefore no striations (bands or stripes). It is divided into two subgroups, single-unit and multiunit smooth muscle. Within single-unit muscle, the whole bundle or sheet of smooth muscle cells contracts as a syncytium. lol i know more than u
Do smooth or skeletal muscle form a functional syncytium?
visceral smooth muscles cells function together as ONE (functional syncytium) multiunit smooth muscle act independently.
What smooth muscles are controlled by autonomic nerves and hormones?
are multiunit muscles.single unit muscle
What type of muscle is found in the walls of hollow organs and in the walls of blood vessels?
multiunit smooth muscle are found in those areas and a few more.
Visceral muscle is also known as what?
single unit smooth muscle
How is smooth muscles different from skeletal muscle?
Cardiac muscle is a type of involuntary striated muscle found in the walls and histologic foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. The cells that comprise cardiac muscle, called myocardiocyteal muscle cells, are mononuclear, like smooth muscle cells.[1]Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems. This complex of actions makes up the systole of the heartSkeletal muscle is a form of striated muscle tissue existing under control of the somatic nervous system. As its name suggests, most skeletal muscle is attached to bones by bundles of collagen fibers known as tendons.Smooth muscle is an involuntary non-striated muscle. It is divided into two sub-groups; the single-unit (unitary) and multiunit smooth muscle. Within single-unit smooth muscle tissues, the autonomic nervous system innervates a single cell within a sheet or bundle and the action potential is propagated by gap junctions to neighboring cells such that the whole bundle or sheet contracts as a syncytium (i.e., a multinucleate mass of cytoplasm that is not separated into cells). Multiunit smooth muscle tissues innervate individual cells; as such, they allow for fine control and gradual responses, much like motor unit recruitment in skeletal muscle.
Which type of muscle is characterized by cells with tapered ends and a single nucleus?
Smooth muscle
