The Neuroendocrine System Flashcards
The ______ is all about how our nerves and hormones team up to control our emotions, growth, and lots more. It’s like a messaging system that tells
our body what to do.
neuroendocrine system
This system affects our moods, behavior, and what it means for our everyday lives.

THE NEUROENDOCRINE SYSTEM IN THE
CONTEXT OF PSYCHOLOGY:
The nervous system uses electrical signals to transmit information quickly, while the endocrine system employs hormones for slower, longer-lasting communication.
Integration of Nervous and Endocrine Systems
THE NEUROENDOCRINE SYSTEM IN THE
CONTEXT OF PSYCHOLOGY:
The hormones released by glands such as the hypothalamus, pituitary gland, adrenal glands, and others have a profound impact on behavior and emotions.
Hormonal Regulation of Behavior and Emotions
THE NEUROENDOCRINE SYSTEM IN THE
CONTEXT OF PSYCHOLOGY:
When we’re stressed, our brain activates a special system called the neuroendocrine system. It’s like an alarm system in our body. The brain tells the adrenal glands to release hormones like cortisol and adrenaline. These hormones help us stay alert and ready to deal with the stress. They make our hearts beat faster and give us extra energy. Once the stress is over, the system calms down, and things go back to normal
Stress Response
THE NEUROENDOCRINE SYSTEM IN THE
CONTEXT OF PSYCHOLOGY:
Imagine your body as a construction site, constantly growing and changing. During
puberty, it’s as if your body is super busy making big changes. Your neuroendocrine system acts like the project manager, overseeing everything from the growth of your bones to the changes in your voice and appearance. Hormones like estrogen and testosterone play key roles in these transformations, turning you from a kid into a teenager.
Development, Puberty, and Neuroendocrine Function
THE NEUROENDOCRINE SYSTEM IN THE
CONTEXT OF PSYCHOLOGY:
Think of your body like a smart thermostat for your house. When it gets too hot, the thermostat cools things down, and when it gets too cold, it warms things up. Similarly, your body has ways to keep things balanced. For example, after you eat and your blood sugar levels rise, your body releases insulin to bring them back down.
Feedback Mechanisms and Hormonal Regulation
Stress Response:
Facing physical danger, such as encountering a predator, being in a car accident, or being physically attacked, can immediately trigger the fight-or-flight response.
Physical Threats
Stress Response:
The perception of a threat, even if it’s not imminent, can activate the fight-or-flight response. This includes situations where individuals feel vulnerable or unsafe, such as walking alone in a dark alley or hearing loud noises in the middle of the night.
Perceived Threats
Stress Response:
Psychological stressors, such as public speaking, financial worries, relationship conflicts, or work pressure, can also activate the fight-or-flight response. These stressors may not pose immediate physical danger but can still be perceived as threatening by the brain.
Psychological Stressors
Stress Response:
Persistent exposure to stressors over time can lead to a chronic activation of the fight-or-flight response. This can have detrimental effects on physical and mental health, contributing to conditions like anxiety disorders, post-traumatic stress disorder (PTSD), and cardiovascular problems.
Chronic Stress
Stress Response:
Intense emotions like fear, anger, or extreme anxiety can also elicit the fight-or-flight response. Emotional stressors can be triggered by various situations, including traumatic events, social confrontations, or sudden surprises.
