The adrenal medulla is comprised of modified sympathetic ganglia neurons which secrete epinephrine and norepinephrine.
What is ganglia?
- In the voluntary and autonomic branches of the peripheral nervous system (PNS), ganglions are collections of neuronal bodies.
- It can think of ganglia as synaptic relay sites between neurons. Information enters the ganglia, activates the neuron there, and then leaves the ganglia.
- All over the body, there are collections of nerve cell bodies called ganglia.
- These ganglia are located adjacent to the thoracic and abdominal/pelvic organs in the head and neck as well as the trunk.
- Their preganglionic neurons are found in the lateral horn of the sacral spinal cord and the cranial nuclei of the brainstem.
- It is an oval-shaped structure that houses the connective tissue, glial, and neuron cell bodies.
- Another way to think of ganglia is as an enclosed grouping of nerve cell bodies that can be located on the outside of the brain and spinal cord.
