GI Anatomy and Physiology Flashcards
The submucosal plexus is also known as plexus
SubMucosal - MEISSNER
The artery supplies the pancreas, small intestine, and colon.
SUPERIOR MESENTERIC ARTERY
The artery supplies the liver, the spleen and the stomach.
CELIAC
The primary vascular supply to the liver is via the .
PORTAL VEIN
The peritoneum covers the external surface of the gastrointestinal tract in the abdominopelvic cavity, while the parietal peritoneum lines the body wall.
VISCERAL
are double layers of peritoneum which extend to the digestive organs from the body wall.
Mesenteries
Digestive organs which have a mesentery are called organs.
INTRAPERITONEAL
The myenteric plexus is also known as plexus.
Auerbach Plexus
The surface of the gastrointestinal tract faces the body cavities.
SEROSAL
is the major means of propulsion in the gastrointestinal tract.
Peristalsis
The artery supplies the large intestine, from the splenic flexure to the upper rectum.
Inferior Mesenteric Artery
The serosal membrane covering the surface of the gastrointestinal tract in the abdominopelvic cavity is termed .
Peritoneum
The walls of the gastrointestinal tract are composed of the following layers, in this order, starting from the lumen: , submucosa, submucosal plexus, circular muscle, myenteric plexus, longitudinal muscle and serosa.
from the LUMEN:
Mucosa Submucosa Submucosal Plexus (Meissner) Circular muscle Myenteric Plexus (Auerbach) Longitudinal Muscle Serosa
The lamina propria layer of the mucosa of the gastrointestinal system is mainly composed of
Connective Tissues
The muscularis mucosae is composed of (smooth/striated) muscle cells.
