Psychology Of Stress

•Stress is a person's response to a stressor such as an environmental condition or a stimulus.•The body's way to respond to stress is by sympathetic nervous system activation which results in the fight-or-flight response.

Summary


Neuroanatomy &

neurochemistry


• Prefrontal cortex: regulate cognitive processes including planning, attention, and problem solving. Becomes impaired during the stress response.

• Hypothalamus: during a stress response corticotropin-releasing hormone (CRH), which stimulates the body’s pituitary gland and initiates a heavily regulated stress response pathway.

• Amygdala: plays a role in the processing of emotions and modulates stress response mechanisms, especially feelings of fear.

• Locus cerulus: is the site of the synthesis of the norepinephrine, which plays an important role in the sympathetic nervous system’s reaction during stress

Glossary

Summary


Neuroanatomy &

neurochemistry

• Hippocamus: important to process prior memories to enhance, suppress, or even independently generate a stress response. It is also an area in the brain that is susceptible to damage brought upon by chronic stress.

• Raphe nuclei: secrets serotonin and modulate changes in circadian rhythm, mood and sensation of pain.

• Spinal cord: Certain nerves that belong to the sympathetic branch of the CNS exit the spinal cord and stimulate peripheral nerves, which in turn engage the body’s major organs and muscles in a fight-or-flight manner.

Glossary

Summary


Neuroanatomy &

neurochemistry

• Pituitary gland: During a stress response, the pituitary gland releases hormones into the blood stream, namely adrenocorticotropic hormone.

• Adrenal gland: Cortisol is the major stress hormone released by the adrenal gland

• Immune system: Cortisol can weaken the activity of the immune system and prevents proliferation of T-cells by affecting the interleukin which is important in combating disease and cancer.
