Sometimes the apparition floated over her bed at night. Once, while visiting Irene, Karen gasped and cried out that Missy was sitting on the sofa. After one of her visits to Missyâs grave, Karen told a friend, her van wouldnât start. âMissy, let me go!â she screamed, convinced that the dead girl was responsible.
Nerve supply. The adrenal glands have a rich nerve supply. These nerves are derived from the coeliac plexus and the thoracic splanchnic nerves. The nerves supply the chromaffin cells of the medulla, but careful microscopy has shown that nerve trunks and plexuses may also appear in the cortical layers.
Function. The adrenal glands are comprised of two parts--the cortex and medulla--that produce hormones (chemicals messengers that regulate body functions).umors of the adrenal glands can secrete excess hormones, causing an increase in blood pressure or heart rate and reducing immune function. Disorders that result in decreased adrenal gland function, such as autoimmune diseases or cancer, can lead to low blood sugar and heart failure.
