- Although we often think of skeletal muscle spasms or cramps, other kinds of muscle, such as smooth muscle, can spasm or cramp. Smooth muscles are found in the walls of hollow organs in your body, such as your stomach, bladder, and blood vessels, and play an important role in normal organ function.

- Medical Definition of Smooth muscle. Smooth muscle: Along with skeletal and cardiac muscle, one of the types of muscle tissue in the body. Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine, and bladder. It is considered smooth because it does not have the microscopic lines (the striations) seen in the other two types of muscle.

- Non-striated Muscle. As the name implies, non-striated muscle lacks visible striations. Smooth muscle is the only muscle of this type and without striations, other less obvious characteristics are used to identify this tissue.Before we examine smooth muscle in longitudinal or cross-section, it might be worth our while to determine why some myofibers are striated while others are not.mooth muscle is found in walls of hollow organs and blood vessels where contractility and stretch are both specific needs. Think of the bladder or the uterus of a pregnant female.

Muscle and Muscle Fibers Smooth muscle tissue is located in the walls of hollow structures such as blood vessels, the stomach, intestines, and the bladder. Smooth muscle fibers are usually involuntary, and they are non-striated (smooth). Smooth muscle tissue, like skeletal and cardiac muscle tissue, can undergo hypertrophy (growth).bjective: The objective of the muscle fiber test is to determine the fiber composition of the muscles being used for a particular exercise. Two test protocols are described: The Dr F. Hatield muscle fiber test and the Charles Poliquin muscle fiber test.

Muscle Muscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis. There are three types of muscle, skeletal or striated, cardiac, and smooth.Muscle action can be classified as being either voluntary or involuntary. Smooth muscle or involuntary muscle 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).

70 10.8 Smooth Muscle Single-unit muscle has its muscle fibers joined by gap junctions so that the muscle contracts as a single unit. This type of smooth muscle is found in the walls of all visceral organs except the heart (which has cardiac muscle in its walls), and so it is commonly called visceral muscle.

- 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.

RIXIMKA DUMARKA Smooth muscle is also found in lymphatic vessels, the urinary bladder, uterus (termed uterine smooth muscle), male and female reproductive tracts, gastrointestinal tract, respiratory tract, arrector pili of skin, the ciliary muscle, and iris of the eye. Also, smooth muscle may contain MHC that is not involved in contraction, and that can arise from multiple genes. 2  Myosin II also contains 4 light chains, resulting in 2 per head, weighing 20 (MLC 20) and 17 (MLC 17) kDa. 3  These bind the heavy chains in the neck region between the head and tail.

Types of Muscle Smooth muscle is also sometimes known as Involuntary muscle due to our inability to control its movements, or Unstriated as it does not have the stripy appearance of Skeletal muscle. Smooth muscle is found in the walls of hollow organs such as the Stomach, Oesophagus, Bronchi and in the walls of blood vessels.he cause of this 'stripy' appearance is the bands of Actin and Myosin which form the Sarcomere, found within the Myofibrils. Skeletal muscles are also sometimes called voluntary muscles, because we have direct control over them through nervous impulses from our brains sending messages to the muscle.

What type of muscle is smooth muscle? All tube like structures in body contains smooth muscles in them. For example, smooth muscles in bronchi, gastrointestinal tract, ureters of kidneys, muscles in uterus(womb.)a … nd smooth muscles in blood vessels. They are all involuntary muscles.That means they are not under your control but under control of autonomic nervous system.

- 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.

Parts of the Muscular System Smooth Muscle. Smooth muscle is found around organs such as your stomach, bladder, and uterus. Smooth muscle works independently, without your conscious input, which is important for life-supporting functions such as digestion. Try it: your food does not fall into your stomach because of gravity.

What Are Involuntary Muscles? TeachPE.com adds that involuntary muscle found in other organs is sometimes called smooth muscle.. Involuntary muscles are found in the stomach, esophagus and lungs, as well as in the walls of blood vessels. While both cardiac and skeletal muscle contain pronounced stripes, involuntary muscle does not. Uic.edu states that involuntary muscle contracts much more slowly than does skeletal muscle.
