Nerve Fibres in the Adrenal Cortex of the Rat

Abstract

IT is generally accepted that the adrenal medulla receives a predominantly pre-ganglionic nerve supply, reaching it via the great and lesser splanchnic nerves and by branches from the lumbar sympathetic chain^1–3. Such fibres traverse the cortex in compact bundles (Fig. 1), without branching or relaying in the cortex, and are easily demonstrable by silver impregnation methods, as is the medullary nerve plexus which they join.
