Secretion of which of the following is completely independent of vagal stimulation?
Gall bladder does not have any secretory activity. It stores and concentrates bile (removes water from bile). Pancreatic and duodenal glands have a parasympathetic vagal innervation. Salivary secretion is almost entirely controlled by neural influences, with the parasympathetic branch of the autonomic nervous system playing the most prominent role.
