Show Answer
Correct Answer – A
Ans. is ‘A’ i.e., Vagus nerve [Rel BDC &/e Vol.3 p. 2901
- Pain sensory fibers to gall bladder are through Vagus, sympathetic and phrenic nerve. Thus gall bladder pain may be referred to-a) Through vagus to the stomach (epigastrium).
- Through the sympathetic nerves to the inferior angle of the right scapula. Lateral horn of thoracic 7 segment of spinal cord gives sympathetic fibres to coeliac ganglion through greater splanchnic nerve. T7 segment receives pain fibres from skin over inferior angle of scapula. So visceral pain is referred to somatic area.
- Through the phrenic nerve to the right shoulder (C4 gives fibres to phrenic nerve and supraclavicular nerves).
