The human body has three main layers of muscle: the skeletal muscle, which is attached to bones and allows for voluntary movement; the smooth muscle, which is found in the walls of internal organs and is involuntary; and the cardiac muscle, which makes up the heart and is also involuntary. Each type of muscle serves a distinct function within the body.
veins have many thin layers with circular elastic and muscle fibres and a wide lumen
The Esophagus has 9 specific layers, if you are healthy. They are: mucosa, saliva, lamina propria, smooth muscle, papillae, muscularis extenma, striated muscle, and adventa.

Smooth muscle tissue has longitudinally and circularly arranged layers.

There are actually FOUR layers of muscle in the stomach. For an effective explanation you need to find a sectional view of the stomach. 1) the muscularis mucosae - a very thin layer of smooth muscle that functions in altering the surface area of the stomach by moving the villi back and forth. 2) Muscularis Externa - there are THREE layers of this muscle in the stomach (compared to only 2 layers in the small intestine.)The following are ordered from innermost layer to outermost layer. >innermost oblique >middle circular >outer longitudinal Happy studying!
The muscle layers of the small and large intestines are composed of smooth muscle tissue, which is specialized for involuntary contractions. This smooth muscle is organized into two layers: an inner circular layer and an outer longitudinal layer, facilitating peristalsis and segmentation movements that aid in digestion and absorption.
