What best describes a stressor?
A stressor is a factor or event that causes stress to an individual, leading to a physical or psychological response. Stressors can be internal (such as thoughts or feelings) or external (such as environmental factors or life events).
What is secondary-appraisal?
Secondary appraisal is the evaluation of one's ability to cope with a stressor or threat, assessing the resources available to manage the situation. It involves considering one's personal strengths, past experiences, and support systems to determine how to address the challenge effectively. This appraisal can impact the individual's emotional response and behavior in response to the stressor.
What is a physiological physical stressor?
A physiological physical stressor is any external factor that disrupts the body's internal balance or homeostasis, leading to a stress response. Examples include intense exercise, temperature extremes, and lack of sleep. These stressors can trigger physiological changes to help the body adapt and cope with the challenging situation.
Is the first stage of Hans Selye and stress model.?
The first stage in Hans Selye's stress model is the Alarm Reaction stage. In this stage, the body perceives a stressor and activates the "fight or flight" response, releasing stress hormones like adrenaline. This stage helps prepare the body to deal with the immediate threat.
What is stress on human systems?
Stress is something you feel when you have an incomplete assignment, or being nervous about something you don't want to tell a friend, teacher, etc. Your palms start to sweet, you might shake, your speech could be scratchy, etc.
What is the difference between a biological stressor and an environment stressor?
A biological stressor is an internal stressor like illness, disability, and injury. An environmental stressor is a condition or event in your physical environment that cause you stress like pollution, poverty, crowding, noise, and natural disasters.
What happens when the sympathetic nervous system is activated and how does it affect the body's response to stress"?
When the sympathetic nervous system is activated, it triggers the body's "fight or flight" response. This leads to increased heart rate, dilated pupils, and the release of stress hormones like adrenaline, preparing the body to react quickly to a perceived threat or stressor.
What does a stressor cause within an organism?
A stressor causes stress within an organism, hence the name. A stressor can be a stimulus like a condition within the environment or triggered by a biological or chemical agent which would be the cause of stress to the organism.
How are stressor and stress related?
they have stress
What best describes a stressor?

What is the first state of stress response?
The first state of the stress response is often referred to as the "alarm reaction," part of the body's fight-or-flight response. This initial phase is triggered by a perceived threat, activating the sympathetic nervous system and leading to the release of stress hormones like adrenaline and cortisol. These hormones prepare the body to react quickly, increasing heart rate, respiration, and energy availability. This acute response is essential for survival, enabling individuals to either confront or flee from the stressor.
When the human body is stressed the hormone adrenaline is released a short time later the body returns to normal this is an example of?
This is an example of the body's stress response, specifically the fight-or-flight response. When faced with stress, the adrenal glands release adrenaline, which prepares the body to react quickly to a perceived threat. Once the stressor is removed, the body activates mechanisms to return to homeostasis, demonstrating the dynamic balance between stress and recovery.
How does stress activate the sympathetic nervous system?
When a person experiences stress, the brain sends signals to the adrenal glands to release hormones like adrenaline and cortisol. These hormones activate the sympathetic nervous system, which triggers the body's "fight or flight" response. This response increases heart rate, blood pressure, and breathing rate, preparing the body to deal with the perceived threat or stressor.
What is an example of physiological physical stressor?
An example of a physiological physical stressor is intense exercise or physical exertion, which can temporarily increase heart rate, blood pressure, and release of stress hormones like cortisol. This stressor can challenge the body's homeostasis and trigger a stress response to adapt and cope with the physical demands placed on it.
What are the three primary players in the body and response to stress?
The three primary players in the body's response to stress are the hypothalamus, the pituitary gland, and the adrenal glands, collectively known as the HPA axis. When a stressor is perceived, the hypothalamus releases corticotropin-releasing hormone (CRH), prompting the pituitary gland to secrete adrenocorticotropic hormone (ACTH). This hormone stimulates the adrenal glands to produce cortisol, the main stress hormone, which helps the body manage stress by regulating metabolism, immune response, and other vital functions. Together, these components orchestrate the physiological and behavioral responses to stress.
What are the three stages of the stress response in what order do they occur?
The three stages of the stress response are the alarm stage, the resistance stage, and the exhaustion stage. In the alarm stage, the body detects a stressor and triggers the fight-or-flight response, releasing stress hormones. Next, in the resistance stage, the body attempts to adapt to the ongoing stressor and maintain homeostasis. Finally, if the stress persists, the exhaustion stage occurs, where the body's resources become depleted, leading to potential physical and mental health issues.
What is the example of alarm reaction?
An example of alarm reaction is the body's immediate "fight or flight" response when faced with a threat or stressor. This can include increased heart rate, heightened senses, and the release of stress hormones like adrenaline to help the body prepare to respond to the perceived danger.
