Smooth Muscle Tissue: Involuntary, Internal Organs & Types - Innerbody
2025年1月11日 · Visceral muscle tissue, or smooth muscle, is tissue associated with the internal organs of the body, especially those in the abdominal cavity. There are three types of muscle in the body: skeletal, smooth, and cardiac.
10.7 Smooth Muscle Tissue – Anatomy & Physiology
Single-unit smooth muscle in the walls of the viscera, called visceral muscle, has a stress-relaxation response that permits muscle to stretch, contract, and relax as the organ expands. Multiunit smooth muscle cells do not possess gap junctions, and contraction does not spread from one cell to the next.
Smooth muscle: Structure, function, location - Kenhub
2023年10月30日 · This type of cells is found in the wall of internal organs and blood vessels (visceral smooth musculature). 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.

2023年8月14日 · Smooth muscle is present throughout the body, where it serves a variety of functions. It is in the stomach and intestines, where it helps with digestion and nutrient collection. It exists throughout the urinary system, where it functions to help rid the body of toxins and works in electrolyte balance.
Muscle Tissue – Anatomy and Physiology - UH Pressbooks
Because these tissues are associated with the contraction of organs, smooth muscles are part of the visceral (organ) motor system. Muscle Tissue Function. Muscle tissue performs at least four primary functions within the human body: Producing body movements; Stabilizing body positions; Storing and moving substances within the body; Generating heat

Visceral Muscle: Development and Histology | Tissues | Human …
The visceral muscle is also known as the plain, non-striated, smooth involuntary muscle. It is called non-striated because it has got no cross-striations. The contraction of this muscle is not controlled by volition or will.
9.8 Smooth Muscle – Fundamentals of Anatomy and Physiology
In certain locations, such as the walls of visceral organs, stretching the muscle can trigger its contraction (the stretch-relaxation response). Axons of neurons in the ANS do not form the highly organised NMJs with smooth muscle, as seen between motor neurons and skeletal muscle fibres.
10.8: Smooth Muscle - Medicine LibreTexts
2022年5月13日 · This allows for the maintaining of muscle “tone” in smooth muscle that lines arterioles and other visceral organs with very little energy expenditure. Smooth muscle is not under voluntary control; thus, it is called involuntary muscle. The triggers for smooth muscle contraction include hormones, neural stimulation by the ANS, and local factors.
Development of Visceral Smooth Muscle | SpringerLink
This review article deals with the origin, differentiation and growth of the smooth musculature of viscera. Only passing references will be made to the development of vascular musculature and to myoepithelial cells and myofibroblasts. The development of smooth muscle should be seen in the context of the special properties of this tissue.
