What is Which of the following is true about nerve supply of adrenal gland? and explain in detail?
Ans. B. Preganglionic fibres from lower thoracic and lumbar veebra come sympathetic chain to supply adrenalsRef: Grays Anatomy, 41" ed., pS. 439Suprarenal gland - Greater autonomic supply than any other organ.The nerves are distributed throughout the gland around blood vessels (regulating blood flow), in the medulla (stimulating the release of catecholamines from chromaffin cells), and in the coex (where they may influence steroid hormone production).A suprarenal plexus lies between the medial aspect ofeach gland and the coeliac and aoicorenal ganglia.It contains predominantly preganglionic syrnpathetic fibres that originate in the lower thoracic spinal segments, reach the plexus branches of the greater splanchnic newes, and synapse on clusters of large medullary chromaffin cells.
