By getting smaller, our hippocampus negatively impacts our memory and learning capacity.

How the Nervous System Interacts With Other Body Systems In addition to helping a person respond to emergencies by mobilizing the body’s energy reserves, these “stress hormones” can stifle the protective effects of antibodies and lymphocytes. The hormones and other chemicals that convey messages among nerve cells also “speak” to cells of the immune system. Some immune cells are able to manufacture typical nerve cell products, and some lymphokines can transmit information to the nervous system.

Effects of stress on memory During times of stress, the body reacts by secreting stress hormones into the bloodstream. Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. Over-secretion of stress hormones most frequently affects memory negatively, but in a few cases can affect it positively. In particular, the hippocampus, prefrontal cortex and the amygdala are affected.

Musculoskeletal System The autonomic nervous system (ANS) has a direct role in physical response to stress and is divided into the sympathetic nervous system (SNS), and the parasympathetic nervous system (PNS). When the body is stressed, the SNS generates what is known as the fight or flight response. The body shifts all of its energy resources toward fighting off a life threat, or fleeing from an enemy. The SNS signals the adrenal glands to release hormones called adrenalin and cortisol.
