guts

enteric means:

submucosal and myenteric

name the two enteric nerve plexuses of the alimentary canal

glands and smooth muscle

located in the submucosa of the alimentary canal, the submucosal nerve plexus controls:

segmentation and peristalsis

the myenteric nerve plexus controls:

lymphatic duct

name the starred structure

lymphatic trunk

name the starred structure

stratified squamous

epithelium is _______________ with many mucus producing glands

esophagus

the ______________ is a 10” long muscular tube found mainly in the mediastinum of the thoracic cavity

mediastinum of thoracic cavity

the esophagus is found mainly in the

esophageal hiatus

the esophagus pierces the diaphragm at the _____________ and joins the stomach

cardiac orifice

the esophagus pierces the diaphragm at the esophagus and joins the stomach at the ______________

gastroesophageal sphincter

the cardiac orifice is surrounded by the:

epithelial membrane

first layer of the alimentary mucosa made of simple columnar cells that function to secrete, absorb, and protect

lamina propria

second layer of the alimentary mucosa made of loose areolar CT containing blood capillaries, MALT, and glands

muscularis mucosae

third layer of alimentary mucosa made of twitching smooth muscle to dislodge food

submucosa

second layer of the alimentary canal made of areolar CT containing many blood and lymphatic vessels, nerves, and elastic fibers

muscularis externa

third layer of the alimentary canal; site of circular and longitudinal smooth muscle; function is peristalsis and segmentation, and circular smooth muscle forms sphincters

serosa

outermost layer of the alimentary canal made of areolar CT and a single layer of squamous epithelial cells
