Evacuarea bilei este consecinta contractiei musculaturii veziculare, in paralel cu relaxarea sfincterului Oddi realizata prin stimulare nervoasa si umorala. Mecanismul nervos se realizeaza prin stimularea:
-
Maduva spinarii
-
Sistemul nervos enteric
-
Nervului vag
-
Trunchiul cerebral
That's Correct!
It's Wrong!
The explanation for the given correct answer is that the evacuation of the bile is a result of the contraction of the vesicular musculature, along with the relaxation of the Oddi sphincter. This mechanism is achieved through nervous and humoral stimulation. The nervous mechanism involves the stimulation of the vagus nerve, which plays a role in regulating various bodily functions, including the contraction and relaxation of muscles in the digestive system. Therefore, the vagus nerve is responsible for stimulating the relaxation of the Oddi sphincter, allowing the bile to be evacuated from the gallbladder.
