Where is myenteric plexus in the body?
between the circular and longitudinal muscle layers
How is the stomach different from other digestive organs?
The stomach is different from other organs of the digestive system because it has three layers of muscle in the muscular is externa. These are the inner oblique layer, the middle circular layer and the outer longitudinal layer.
Detrusor muscle what are the 3 layers?
Outer = longitudinal smooth muscle Middle= circular smooth muscle Innermost= longitudinal smooth muscle
What are the three layers of smooth muscle that form the wall of the vas deferens?
outer layer ============= longitudinal middle layer================ circular inner layer============ longitudinal
Which wall of the alimentary canal is actually organized into two distinct layers?
The muscularis layer of the alimentary canal is organized into two distinct layers: an inner circular layer and an outer longitudinal layer. This arrangement allows for coordinated peristaltic movements, facilitating the movement of food along the digestive tract. The circular layer constricts the lumen, while the longitudinal layer shortens the segment of the canal, enhancing the efficiency of digestion and propulsion.
What tissue layer provides for primary digestive motility?
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.
What are the subdivisions of muscularis externa?

Functions of circular and longitudinal muscles in annelids?
In annelids, circular and longitudinal muscles work together to facilitate movement and locomotion. The circular muscles contract to elongate and narrow the body segment, while the longitudinal muscles contract to shorten and widen it. This coordinated action allows for both peristaltic movement, which helps the worm move through soil or water, and the ability to anchor parts of the body during burrowing or crawling. Together, these muscle layers enable efficient movement and adaptability in various environments.
What is the difference about the muscularis layer of the stomach compared to the rest of the alimentary canal?
The muscularis layer of the stomach has a unique structure compared to the rest of the alimentary canal, as it consists of three distinct layers of smooth muscle: an inner oblique layer, a middle circular layer, and an outer longitudinal layer. This three-layered arrangement allows for more complex and powerful contractions, facilitating the churning and mixing of food with gastric juices. In contrast, the muscularis layer in other parts of the alimentary canal typically consists of only two layers (circular and longitudinal), which are primarily responsible for peristalsis and the movement of food along the digestive tract.
Which layer of the alimentary canal is made of the smooth muscle involved in peristalsis?
The muscular layer responsible for peristalsis in the alimentary canal is the muscularis externa. It is composed of smooth muscle fibers arranged in circular and longitudinal layers that contract and relax to push food along the digestive tract through coordinated movements known as peristalsis.
How does this modification relate to the function of the stomach?
The modification enhances the stomach's ability to produce digestive enzymes or increase its capacity to store food. This could improve digestion and nutrient absorption in the stomach, leading to better overall digestive function.
How many layers of tissue from the walls of the digestive tract?
Four layers of tissue form the walls of the digestive tract. These layers are called mucosa, submucosa, muscularis externa and adventitia.
