digestive 2 Flashcards
Major salivary glands have also myoepithelial cells
t
Pancreas is a compound seromucous gland
f
Beta cells of pancreatic Langerhans islets produce Insulin
t
Langerhans islets form the exocrine part of the Pancreas
f
The exocrine part of Pancreas contains in addition to serous secretory cells also the
centroacinar cells
t
The exocrine part of Pancreas has both intercalated and striated ducts
t
Intercalated ducts with centroacinar cells is typical structure of Pancreas
t
The exocrine part of Pancreas is made up of acini and ducts
t
Tunica mucosa of Gallbladder contains numerous serous glands producing bile
f
Mucosa of Gallbladder exhibits huge folds which are covered by tall simple columnar
epithelium with microvilli
t
Tunica serosa of Gallbladder contains numerous serous glands producing bile
f
In the Gallbladder, on the border between Tunica mucosa and Tunica submucosa, there is
a well-developed Lamina muscularis mucosae
f
n the gallbladder there is a well-developed Lamina muscularis mucosae on the border
between Tunica mucosa and Tunica submucosa
f
The mucosa of the gallbladder contains Lamina muscularis bordering the Submucosa
f
The wall of Gallbladder does NOT contain any Tunica submucosa
t
The middle layer of Gallbladder is formed by bundles of muscle fibres of transversely
striated muscles
f
Hering´s bile ducts are part of Gallbladder
f
Herings bile ducts are the structure of Gallbladder
f
In a hepatic lobule, the cord or plates of hepatocytes are disposed in a radial pattern from
the V. centralis to the periphery of the lobule
t
Ito cells (hepatic stellate cells) can be found in space of Disse
t
Liver Kupffer cells are derived from monocytes and located from luminal part of sinusoid s
t
Structures of hepatic triad are embedded in loose collagenous CT
t
Hepatic sinusoids are lined by mesothelium
f
The 3 main structures in the porta triad are interlobular vein, artery and bile duct
f
The smallest bile capillaries (Canaliculi biliferi) in the liver do NOT have their own wall, they
are bounded by adjacent hepatocytes
t
Space of Disse is a part of intrahepatal bile duct system
f
Disse´s liver space is a narrow liver space between sinusoid endothelial cells and
hepatocytes
t
The perisinusoid space of the liver is defined by the sinusoid epithelium and hepatocytes
with numerous microvilli
T
Disses´ space of liver is a narrow space between the endothelial cells of the sinusoid and
hepatocytes
T
Space of Disse is the site of exchange of materials between blood and liver cells
T
Space of Disse is the space between sinusoidal endothelium and hepatocytes covered by
many microvilli
f
Hepatocytes are large eosinophilic polarized cells, deposited in lines, sometimes having
two nuclei
t
Hepatocytes are large eosinophilic polarized cells, placed in beams, sometimes having two
nuclei
t
Odontoblasts are tall columnar cells and their bodies are situated at the border between
dentin and tooth pulp
t
The Enamel, Dentin and Pulp of the tooth belong to hard tissues of tooth
f
Enamel is of ectodermal origin
t
In the crown of the tooth, the bodies of odontoblasts form 6-8 layers, in contrast to the
root where they form only one layer
f
Cementum of the tooth is avascular, even its composition is similar to the bone content
t
Internal aspect of the lip (mucosal part) does NOT contain neither sebaceous nor sweat
glands
t
The outer side of the lip contains numerous sebaceous and sweat glands
t
There is no Lamina muscularis mucosae in Lamina propria of the oral mucosa
t
Gingiva comprises stratified squamous epithelium with parakeratinization and Lamina
propria extending to tall papillae
t
Masticatory epithelium is a keratinized, in some places parakeratinized stratified
squamous epithelium
t
