The detrusor muscle, which is the smooth muscle layer of the bladder, primarily comprises the muscularis propria. It does not invade the inner or outer half of the muscularis propria, as it is a part of this layer itself. The muscularis propria consists of interwoven bundles of detrusor muscle fibers that facilitate bladder contraction. Thus, the detrusor muscle is integral to the structure of the muscularis propria rather than invading it.
Muscularis propria, also known as muscularis externa, is a layer of muscle found in the walls of various hollow organs, such as the gastrointestinal tract. It typically consists of two layers of smooth muscle: an inner circular layer and an outer longitudinal layer, which facilitate peristalsis and the movement of contents through these organs. This muscular layer plays a crucial role in the function of organs like the esophagus, stomach, and intestines, enabling coordinated contractions.
muscularis
Assuming you mean muscularis, it's a part of the layers found around our Gastrointestinal system and other systems in our body (Reproductive tract etc). The 4 layers are: 1. mucosa (epithelial layer) 2. submucosa 3. muscularis 4. serosa Muscularis has both longitudinal and circular muscle layers (in the GI tract this is smooth muscle which is used for peristalisis, haustration, etc). Muscularis layer is contractile and used in the GI tract for moving food through the system, or in the reproductive tract for contractions for birth, etc. Hope this helps?
The smooth muscle layer, known as the muscularis externa, is responsible for primary digestive motility in the gastrointestinal tract. It consists of inner circular and outer longitudinal muscle layers that work together to propel food through the digestive system via peristalsis.
The detrusor muscle is the main muscle within the bladder that contracts during urination to help expel urine. It is a smooth muscle that forms a triangular shape at the base of the bladder.
The mucosa is divided into three layers: epithelium, lamina propria, and muscularis mucosae. The epithelium is the outermost layer, followed by the lamina propria, which is a thin layer of connective tissue. The muscularis mucosae is the innermost layer, consisting of smooth muscle cells that help with movement and function of the mucosa.
Muscularis propria is a layer of smooth muscle found in the gastrointestinal tract. It is located between the mucosa and the submucosa, and its main function is to provide motility for the movement of food through the digestive system.
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.
Muscularis propria, also known as muscularis externa, is a layer of muscle found in the walls of various hollow organs, such as the gastrointestinal tract.

This muscular layer plays a crucial role in the function of organs like the esophagus, stomach, and intestines, enabling coordinated contractions.
The muscularis mucosa separates the lamina propria from the submucosa. It produces local movements of the mucosa. For example, twitching of this muscle layer dislodges food particles that have adhered to the mucosa.
Detrusor muscle is found in the urinary bladder.
urinary bladder
Smooth Muscle - Muscularis Mucosa
muscularis
The inner layer of the ureter is the mucosa. The mucosa consists of transitional epithelium and lamina propria. Lamina propria is composed of areolar connective tissue. The middle layer is the muscularis. This consists of smooth muscle. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. A portion of the outer layer is covered in serosa.
Outer = longitudinal smooth muscle Middle= circular smooth muscle Innermost= longitudinal smooth muscle
The muscle that compresses the urinary bladder during micturition is the detrusor muscle. This smooth muscle layer surrounds the bladder and contracts to expel urine from the bladder into the urethra. The contraction of the detrusor muscle is primarily controlled by the autonomic nervous system, specifically the parasympathetic division.
