Dissector Answers - Posterior Mediastinum Smooth muscle is present throughout the body, in blood vessels and skin, but is most often considered in the context of thoracic, abdominal, and pelvic viscera. In that it innervates muscle, causing contraction or relaxation, the ANS is similar to the system of skeletal muscle innervation.

- 1 Smooth muscle, neither striated in structure nor under voluntary control, is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector pili in the skin (in which it controls erection of body hair).his is opposed to other components or tissues in muscle such as tendons or perimysium. It is formed during embryonic development through a process known as myogenesis. Muscle tissue varies with function and location in the body.

What Is the Function of the Muscular System? Smooth muscles, or involuntary muscles, are not controlled consciously. They are controlled by the autonomic nervous system, and found and in around your circulatory, lymph and intestinal systems. Smooth muscles are not attached to bones, move slowly and can stay contracted for long periods of time.

Basic Cable Channels Basic channels also air more commercials than premium channels because the lower customer fees do not cover the costs of transmitting the channels. Depending on the provider, the number of basic cable channels can vary widely. Typically, cable companies offer somewhere between 30 and 70 channels in their basic cable packages. All of these main networks are available to basic cable channels subscribers: ABC — Founded in 1943, the ABC is one of the major networks available to basic cable customers.

- Smooth muscle is called involuntary muscle because you can not control this type of muscle movement. These muscles line internal organs, blood vessels, and organs such found in the digestive and reproductive systems. Structurally, these muscle fibers appear non-striated (not striped) when magnified, have one nucleus per cell, and are usually short.

Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.

SMOOTH MUSCLE CONTRACTION AND RELAXATION Layers of smooth muscle cells line the walls of various organs and tubes in the body, and the contractile function of smooth muscle is not under voluntary control. Contractile activity in smooth muscle is initiated by a Ca2+-calmodulin interaction to stimulate phosphorylation of the light chain of myosin.

Difference Between Smooth Muscle and Cardiac Muscle Smooth muscles are of two major types known as single unit, aka unitary, smooth muscles and multi-unit smooth muscles. The single unit smooth muscles contract and relax together, as the nerve impulse excites only one muscle cell, and that is passed on to other cells through gap junctions. In other words, a unitary smooth muscle functions as a single unit of cytoplasm with numerous nuclei.

Vascular smooth muscle Vascular smooth muscle cells, isolated from human aorta, growing and forming a monolayer in cell culture. Vascular smooth muscle refers to the particular type of smooth muscle found within, and composing the majority of the wall of blood vessels.rteries have a great deal more smooth muscle within their walls than veins, thus their greater wall thickness. This is because they have to carry pumped blood away from the heart to all the organs and tissues that need the oxygenated blood.

Muscle tissue Smooth muscle is an involuntary non-striated muscle. It is divided into two subgroups; the single-unit (unitary) and multiunit smooth muscle. Within single-unit cells, the whole bundle or sheet contracts as a syncytium (i.e. a multinucleate mass of cytoplasm that is not separated into cells).ultiunit smooth muscle tissues innervate individual cells; as such, they allow for fine control and gradual responses, much like motor unit recruitment in skeletal muscle.

Structure and Functions of Muscular Tissue Contractions of smooth muscle constrict (i.e. narrow = reduce the diameter of) the vessels they surround. This is particularly important in the digestive system in which the action of smooth muscle helps to move food along the gastrointestinal tract as well as breaking the food down further.

- Smooth muscles — sometimes also called involuntary muscles — are usually in sheets, or layers, with one layer of muscle behind the other. You can't control this type of muscle. Your brain and body tell these muscles what to do without you even thinking about it. You can't use your smooth muscles to make a muscle in your arm or jump into the air. But smooth muscles are at work all over your body.
