Ventromedial nuckeys ve ventrolateral nucleusların görevi
Medail satiety
Lateral feeding
Temperature and feeding relation
Cold stimulates feeding
Write down the anorexigenic substances
Alpha msh Leptin Serotonin Norepinephrine Crh İnsulin glucagon Peptide YY
Write down the orexigenic substances
Neyropeptide Y Agrp Orexins Endorphin Galanin Gherlin Cortisol
What does pomc/cart cell secrete in order to decrease feeding
Alpha msh
Where does thirst center located
Supraoptic area
How does Hemmorhage effect drinking
It increases drinking despite unchanged extracellular osmality
Write down the major glands in stimulated and unstimulated conditions
Uns submandibular
Stim parotid
Explain the ionic content of the saliva
Rich in K and Bicarbonate
Poor in sodium and chloride
Explain the osmality of primary and secondary saliva output
Primary isotonic
Secondary hypotonic
As ductal cells are impermiable to water
What happens the concentration of sodium if rate of saliva secretion is high
It will increase in concentration
Why do we gice atropine to patient who is going to take anesthesia
Prevent secretion trickling into trachea via stopping the saliva output
Write down tge adh and aldosteron action on saliva
Doesnt change rate of secretion but ionic composition
Aldısteron increases absorption of Na and secretion of K
Adh enhances Na absorption
They only act on ductular cells
Explain the osmality of bile secretion
Rich in bicarbonate
Similar na and k to plasma
Lower cl than plasma
İsotonic solution
What is the effect of secretin on bile secreton
Volume of flow and bicarbonate increases
Bile acid doesnt increase
Ehich hormone is effective on emptying of gallbladder
Cck
Why do we give drugs that inhibit reabsorption bile to patient with high cholesterol
Thus decreased reabs will lead increase in bile acid production which uses chılesterol
Explain the abs of bile in distal portion
It is active transport
Active transport has higher affinity to conjugated bile
Ecplain the choleretic effect
Bile acid in portal blokd stimulate the secretion of bile but inhibit synthesis
Where does distention of bile duct localises
Mid epigastriumor right subcostal region
In the absence of which hormone pancreas go intı atrophy
Cck
At high flow rate what will be the composition of pancreas
?
What is the effect of secretin and cck on pancreas
Secretin uses cAMP. Strong stimulus for HCO3 weak stimulus for enzymes
Cck uses Ca. Vice versa
Pain type of pancreayic diseases
Located in upper abdomen
Radiates to back
Relief by sitting or bending up
