Innervation of the GI tract and accessory glands Flashcards
What is extrinsic nervous system?
Nerves that innervate the gut with cell bodies located outside the gut wall
What is intrinsic nervous system?
Nerves that innervate the gut with cell bodies which are contained within the wall of the gut
The enteric nervous system is intrinsic nervous system. T/F
T
The extrinsic nervous system is part of the ANS. T/F
T
Vagus and pelvis nerves: parasympathetic or sympathetic?
Parasympathetic
Parasympathetic innervation of esophagus: vagus or pelvic nerves?
Vagus
Parasympathetic innervation of stomach: vagus or pelvic nerves?
Vagus
Parasympathetic innervation of distal part of colon: vagus or pelvic nerves?
Pelvic
Parasympathetic innervation of proximal part of colon: vagus or pelvic nerves?
Vagus
Parasympathetic innervation of gallblader: vagus or pelvic nerves?
Vagus
Parasympathetic innervation of the pancreas: vagus or pelvic nerves?
Vagus
Parasympathetic innervation of anorectal region: vagus or pelvic nerves?
Pelvic
The preganglionic cell bodies of the vagus are in the brainstem. T/F
T
The preganglionic cell bodies of the pelvic nerves are in the medulla. T/F
F
They are in the sacral spinal cord.
The efferent transmission pathway from the preganglionic nerve cell bodies is always via the ENS. T/F
T
The post ganglionic neurons are neurons of the ENS.
