Lecture 27: Accessory Glands Flashcards
what are the three pairs of salivary glands
- parotid (largest)- 30% saliva
- Submandibular- 40% saliva
- Sublingual- 30%
which CN supplies parotid gland
CN IX PSN fibres regulate secretion parotid gland
which CN supplies submandibular
CN VII
which CN supplies subglingual
CN VII SN fibres
- parotid ducr
- parotid gland
3.masseter
4.submandibular duct - submandibular gland
6.sublingual gland - ducts sublingual
accessory glands
liver
salivary glands
gall bladder
pancreas
what region is liver in
right hypochondriac, epigatric, left hypochondriac region
how is liver connected to stomach
via lesser omentum and anterior abdo wall thru falciform ligament
inferior surface liver
abdominal viscera “visceral surface”
diaphragmatic surfaces of liver
=anterior,posterior,superior,right
porta hepatis
transverse fissure near center of visceral surface of liver. passageway for hepatic arteries, hepatic portal vein, hepatic bile duct, hepatic nerve pleux, lymphatic vessels
coronary ligament
peritoneal reflection attaching liver to under surface of diaphragm
falciform ligament
attach anterior surface liver to posterior surface abdo wall.
divides liver in R and L
round ligament of liver
remnant of umbilical vein
1.gallbladder
2.right lobe
3.coronary ligamen
4.left lobe
5. falciform ligament
6. round ligament
are caudate and quadrate lobe part of R or L lobe liver?
anatomically, they are subdivisions of right lobe BUT physiologically, they are part of L (same blood supply, nerve, bile)
- caudate
- quadrate
1.hepatic artery proper
2. hepatic portal vein
3. porta hepatis
4. IVC
5.coronary ligament
6.common bile duct
where is caudate lobe
R lobe.
posterior, next to IVC
porta hepatis
3 main structures:
1. common bile duct
2. hepatic porta vein
3. hepatic artery proper (branch of celiac)
main fxn liver
produce bile, which emulsifies fat so that enzymes that digest fat have more SA to act on. co
fxn gall bladder
concetration bile, then inject into duodenum
- right hepatic duct
- cystic duct
- neck of gallbladder
- body of gallbladder
- fundus of gallbladder
- common bile duct
- left hpeatic duct
- common epatic duct
hepatic ducts
R collects bile from R lobe, L from left lobe and caudate and quadrate
join together to form common hepatic duct (drains entire liver)
common hepatic duct receives cystic duct and then necomes common bile duct
flow of bile
L and R hepatic duct pass bile to common hepatic duct, dilute bile goes through cystic duct, enters gall bladder, concentrated. When needed, passed again thru cystic duct, but goes DOWN common bile duct and injected into duodenum (SECOND PART)
- common bile duct
- major duodenal papilla
- main pancreatic duct
- tail of pancreas
explain location pancreas
head is partially surrounded by duodenum
body sits behind stomach
tail extens to hilum of spleen
retroperitoneal organ. fixed to posterior abdo wall by peritoneum
fxn pancreas
endocrine and exocrine. produces hormones and digestive enzymes
fxn pancreatic duct
drain exocrine features of pancreas (digestize enzymes). unites with common bile duct and drains into major duodenal papilla
sympathetic/PSN supply to liver and gall bladder
greater splachnic and vagus nerve via celiac plexus
blood supply liver/gall bladder
common hepatic branch of celiac artery
sympathetic/PSN supply to pancreas
greater splachnic and vagus nerve via celiac and superior mesenteric plexuses
blood supply pancreas
common hepatic and splenic branche of celiac artery as well as superior mesenteric artery
which organs does celiac artery supply
stomach, spleen, pancreas, liver
