Effect of sympathetic innervation to muscularis mucosa?
Sympathetic innervation to the muscularis mucosa causes vasoconstriction of blood vessels in this layer, reducing blood flow in response to stress or danger. This helps divert blood to vital organs during fight-or-flight responses.
What is the function of camouflage in the wild?
Camouflage is the process of blending into the background. It only works if the predator hunts by looking - animals who hunt by sound or smell are not fooled by camouflage! Many animals have color patterns which match the environment in which they live. If they freeze against this background, they blend in and are harder to see.

What is the function of rectum in a fetal pig?
The function of the rectum in a fetal pig is the same as the function in a human. It is the area that gets rid of the waste that the body does not use.
How does the muscularis externa of the stomach relate to the function?
The third layer, the obliquely oriented layer, of smooth muscle in its muscularis externa allows the stomach to churn, mix, and pummel the food, physically reducing it into smaller pieces.
What is the function of the muscularis externa in the stomach?
The muscularis externa is the layer of the digestive tube, which consists of smooth muscles. It mixes ingested food with gastric juices so digestion is able to occur.
What are the subdivisions of the layer of muscularis?
The subdivisions of the wall layer muscularis externa are the longitudinal layer, circular layer, and oblique layer.
What are the four layers of the digestive tract?
Mucosa, Submucosa, Muscularis externa, and the Serosa
Which layer of the alimentary canal is responsible for segmentation and peristalsis?
the smooth muscles are responsible for perstalsis and segmentation, so that means its the muscularis externa. :)
Which of the following is the correct order of the layers of the gastrointestinal tract wall from lumen to external surface?
The correct order of the layers of the gastrointestinal tract wall from lumen to external surface is mucosa, submucosa, muscularis externa, and serosa (or adventitia depending on the location in the body).
How is the muscularis externa of the stomach modified?
The muscularis externa of the stomach is modified into three layers of smooth muscle: an inner oblique layer, a middle circular layer, and an outer longitudinal layer. This unique arrangement allows for the mixing and movement of stomach contents during digestion.
What are the 4 histological layers of the gut?
The four histological layers of the gut are the mucosa, submucosa, muscularis externa, and serosa (or adventitia). The mucosa is the innermost layer, containing epithelial cells and glands. The submucosa provides support and contains blood vessels and nerves. The muscularis externa is responsible for peristalsis, and the serosa (or adventitia) is the outermost layer providing protection and support.
What are the subdivisions of muscularis externa?

How many layers has stomach?
The stomach has four main layers: the mucosa, submucosa, muscularis externa, and serosa. The mucosa is the innermost layer that produces gastric juices, while the submucosa contains blood vessels and nerves. The muscularis externa consists of smooth muscle that aids in digestion through contractions, and the serosa is the outermost layer that provides protection and support. Each layer plays a crucial role in the stomach's function and overall digestive process.
What are the subdivisions of mucosa?
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.
What are 2 types of movements produced by contractions of the muscularis externa?
The two types of movements produced by contractions of the muscularis externa are peristalsis, which is a coordinated contraction and relaxation of circular and longitudinal muscles to propel food along the digestive tract, and segmentation, which involves the mixing and churning of food within a specific region of the digestive tract for digestion and absorption.
