31
1. identify 2. what type of valve is in here? what is its function
1. cystic duct 2. cystic duct is kept open by a spiral valve in the distal part of the neck, thereby allowing bile to flow back intohe gallbladder if the distal end of the bile duct is closed (due to action of the sphincter of the bile duct).
32
1. identify 2. what ducts is it attached to? 3. where does it enter the duodenum?
1. common bile duct * to anatomical right of hepatic artery which is almost always in the middle* * enters the duodenum* 2. attaches to the cystic duct and the pancreatic duct 3. joins with pnacreatic duct and enters descending duodneum and forms the hepatopancreatic amupulla
33
what is the difference between celiac ganglia and celiac plexus? what is in the celiac plexus? what synapses here? what are the fiber components where is it distributed to\>
\*located on nthe abdominal aorta near the celiac trunk plexus: - (2) celiac ganglia (greater splanchnic from T5-T9), - (1) superior mesenteric ganglia (lesser splanchnic from T10-T11) - (1) paired aorticorenal ganglia (least splanchnic from T12) what synapses here?: all the throacic splanchnics components: post gang. sympp, pregang, visceral afferent pain, parasympathetic from vagus, visceral afferent montiring distributed to: branches of celiac trunk (anterior gastric to stomach and liver), superior mesenteric (posterior gastric to spleen and pancreas), renal, and gonadal arteries
34
what is the nerve innervate of the Stomach, liver, pancreas, small bowel, cecum, ascending and transverse colon, kidneys
Sympathetic from: thoracic splanchnic (greater, lesser, least) b. Parasympathetics from: anterior and posterior gastric nerves (from celiac ganglia) c. Visceral afferent pain: follow thoracic splanchnics d. Visceral afferent monitoring: follow gastric nerve
35
what is the nerve innvervation from Descending and sigmoid colon, rectum, bladder, reproductive organs
Sympathetics from: lumbar splanchnic nerves b. Parasympathetics from: pelvic splanchnics c. Visceral afferent pain: follow lumbar splanchnics d. Visceral afferent monitoring: follow pelvic splanchnics
36
what is this? what spina level does it arise from? what is the first branch from it? structures supplied by this artery..where is the referred pain?
SMA \*1 cm below celiac trunk.. goes behind the neck of the pancreas nferior Pancreaticoduodenal Artery is the first brnach t8-T12
37
what is this? wehre is referred pain from structures supplied to this go? what are the structures supplied by the ima and its branches
ima going more towards left before birfucation of the abdominal aorta l1-l2 supplies: descending colon and left part of transverse colon caudal part of descending colon, sigmoid colon, and rectum
38
what is this? at what spinal level do they come off? which side is higher and shorter?
1. renal arteries 2. l1-l2 3. left side is higher on aorta and shorter
39
how may pairs of lumbar arteries are there? what do they supply?
4-5 pairs \*about between level of renal arteries to bifurcation of the aorta supply the lumbar vertebrae, the back muscles and the posterior abdominal wall.
40
what is this? what does it secrete? which is larger in shape: right or left? what are the parts of this? whats the embryologicla origin of each part? where do the lympathics for these glands drain where do left and right suprarenal veins drain?
suprarenal gland secrete corticosteroids, androgens, epinephrine and norepinephrine. left is larger cortex: from mesoderm (and make cortiocsteroids and androgens) medulla: from neural crest \*great splanchnics synapse on here drains into lumbar splanchnics right into IVC and left suprarenal vein into left renal vien
41
what is this? what may drain intO?
cisterina cyli \*about L2 so look below renal artiers on the aorta but above ima drains some of the lympathics from liver, all of intestinal and lumbar lymphatics
42
what is this? what do they drain into? is it longer/higher than left? where does it get blood from
right renal vein IVC the left is longer and higher blood from: he left gonadal vein and left suprarenal vein, as well as other area
43
left suprarenal vein
44
right gonadal vein (OFF OF THE IVC)
45
what is this? what is its clinical importance
left gonadal vein (\*GOING INTO LEFT RENAL VEIN) testicular variocele is more common on left becasue testicular vein is attached to renal vein.. if renal vein becomes blocked
46
what is this? what are inside its renal columns?
renal cortex projects between the medullary pyramids as renal columns glomeruli and some portions of renal tubules
47
what is this?? what is contained in pyramids?
renal medulla \*the innermost part of kidney forms 10-15 medullary pyramids inside each pyamid: collecting ducts and and protions of renal tubules (renal tubules in both cortex and medulla)
48
what is this? what contains it?
renal pelvis it is contianed by the RENAL SINUS... a expansion behind the hilum and contains the renal pelvis, calyxes, and the major renal vessel
49
what is this? where does it collect urine from?
minor calyases collects urine from papilla (or tip) of medullary pyramid
50
what is this? what is it formed by? where does it drain urine to?
major calyx formed by 2 or more minor calyxes drains urine to renal pelvis
51
what is this? where is it the thinnest?
ureter The ureters are naturally/physiologically narrow in three places: i. Uretero-pelvic junction ii. As the ureter passes over the iliac vessels, at the pelvic brim iii. At junction with the urinary bladder
