    Study Notes

    Homeostasis and Stress Response

    • Homeostasis is the body's ability to maintain internal stability in response to environmental changes.
    • Walter Cannon, an American doctor, studied homeostasis and coined the term "Fight or Flight Response" to describe the body's response to stressors.

    Fight or Flight Response

    • The Fight or Flight Response is a homeostatic response to threats or dangers, preparing the body to either fight or flee.
    • This response involves the nervous system and endocrine system.
    • The sympathetic nervous system is responsible for initiating the Fight or Flight Response.
    • The autonomic nervous system, a branch of the nervous system, controls involuntary actions, including the sympathetic nervous system.
    • In the Fight or Flight Response, the body experiences:
      • Increased heart rate to pump blood with oxygen and nutrients.
      • Increased respirations to intake oxygen and expel carbon dioxide.
      • Peripheral vasoconstriction to direct blood to the core and vital organs.
      • Shutdown of non-essential functions, such as digestion and immune function.

    Endocrine System's Role in Fight or Flight Response

    • The endocrine system supplies hormones that support the sympathetic nervous system.
    • The adrenal glands, located on top of the kidneys, produce hormones that contribute to the Fight or Flight Response.
    • The adrenal medulla produces catecholamine hormones, including epinephrine and norepinephrine, which increase heart rate and blood pressure.
    • The adrenal cortex produces glucocorticoids, including cortisol, which redistributes glucose energy and suppresses the immune system.

    Tend and Befriend Response

    • The Tend and Befriend Response is an alternative response to stress, characterized by affiliative behavior and social support.
    • Oxytocin, a hormone associated with pair bonding, moderates the stress response and is involved in the Tend and Befriend Response.

    General Adaptation Syndrome (GAS)

    • Hans Selye's research built upon Cannon's work and led to the concept of the General Adaptation Syndrome (GAS).
    • GAS describes the body's adaptive response to stress, consisting of three phases:
      • Alarm Phase: initial stress response, characterized by increased heart rate, blood pressure, and resource mobilization.
      • Resistance Phase: the body attempts to fight or flee, with elevated temperature, blood pressure, and breathing rate, and increased stress hormone production.
      • Exhaustion Phase: prolonged stress leads to depleted resources, damage to tissues and muscles, and increased susceptibility to illness.

    Consequences of Chronic Stress

    • Chronic stress can have damaging effects on the body, including tissue damage, muscle damage, and impaired immunity.
    • The body is equipped to handle short-term stress, but prolonged exposure to stress can lead to exhaustion and negative consequences.

    Homeostasis and Stress Response

    • Homeostasis is the body's ability to maintain internal stability in response to environmental changes.
    • Walter Cannon coined the term "Fight or Flight Response" to describe the body's response to stressors.
