Verified step by step guidance

Step 1: Begin by understanding the peripheral nervous system (PNS), which is divided into the somatic nervous system and the autonomic nervous system. The autonomic nervous system controls involuntary functions such as heart rate, digestion, and glandular activity.

Step 2: Learn about the autonomic nervous system's two main divisions: the sympathetic division and the parasympathetic division. The sympathetic division is responsible for the 'fight or flight' response, while the parasympathetic division manages 'rest and digest' activities.

Step 3: Recognize the role of the adrenal medulla, which is a part of the adrenal glands located above the kidneys. The adrenal medulla secretes hormones like adrenaline (epinephrine) and noradrenaline (norepinephrine) during stress responses.

Step 4: Understand that the adrenal medulla is directly stimulated by the sympathetic division of the autonomic nervous system during a 'fight or flight' response. This stimulation leads to the release of hormones that prepare the body for immediate action.

Step 5: Conclude that the adrenal medulla is part of the sympathetic division of the autonomic nervous system, as it plays a key role in the body's response to stress and emergencies.
