AP Psych Endocrine System and Behavior
40 flashcards covering AP Psych Endocrine System and Behavior for the AP-PSYCHOLOGY Unit 2: Biological Bases section.
The endocrine system plays a crucial role in regulating behavior through hormone secretion, impacting various physiological and psychological processes. According to the College Board's AP Psychology Curriculum Framework, understanding the interplay between the endocrine system and behavior is essential for grasping the biological bases of psychology. This unit covers key glands, such as the pituitary, thyroid, and adrenal glands, and their functions in influencing mood, stress responses, and overall behavior.
On practice exams, questions about the endocrine system often focus on identifying glands and their associated hormones, as well as understanding their effects on behavior. A common pitfall is confusing the roles of different hormones or misidentifying which gland produces them. For instance, students might mix up the functions of cortisol and adrenaline or overlook the feedback mechanisms that regulate hormone levels. Remember, recognizing the broader implications of hormonal changes in real-world scenarios, like stress management in the workplace, is often overlooked but critical for effective application.

What hormone regulates blood sugar levels?
Insulin is the hormone that regulates blood sugar levels by facilitating the uptake of glucose into cells (College Board AP CED).
- 10
Under what conditions does the body release cortisol?
The body releases cortisol in response to stress, helping to regulate metabolism and the immune response (College Board AP CED).
- 11
Which gland secretes growth hormone?
The anterior pituitary gland secretes growth hormone, which is essential for growth and development (College Board AP CED).
- 12
What is the effect of oxytocin on behavior?
Oxytocin is known to enhance social bonding, trust, and emotional connections between individuals (College Board AP CED).
- 13
A patient presents with excessive thirst and frequent urination. What hormone is likely involved?
The symptoms of excessive thirst and frequent urination suggest a problem with antidiuretic hormone (ADH), which regulates water balance in the body (College Board AP CED).
- 14
What is the function of thyroid hormones?
Thyroid hormones regulate metabolism, energy levels, and overall growth and development in the body (College Board AP CED).
- 15
How does the endocrine system influence mood?
The endocrine system influences mood through the release of hormones such as serotonin and cortisol, which affect emotional states and stress responses (College Board AP CED).
- 16
What is the role of the adrenal glands?
The adrenal glands produce hormones such as adrenaline and cortisol, which are involved in the stress response and metabolism regulation (College Board AP CED).
- 17
When is melatonin released, and what is its effect?
Melatonin is released in response to darkness and helps regulate sleep-wake cycles (College Board AP CED).
- 18
Define 'negative feedback' in the context of the endocrine system.
Negative feedback in the endocrine system refers to a process where the release of a hormone is inhibited by the hormone's effects, maintaining homeostasis (College Board AP CED).
- 19
What hormone is involved in regulating the sleep-wake cycle?
Melatonin is the hormone primarily involved in regulating the sleep-wake cycle, promoting sleepiness in response to darkness (College Board AP CED).
- 20
Which endocrine disorder is characterized by low levels of insulin?
Diabetes mellitus is characterized by low levels of insulin, leading to high blood sugar levels (College Board AP CED).
- 21
How does estrogen affect behavior?
Estrogen influences behavior by affecting mood, cognitive function, and social interactions, particularly in females (College Board AP CED).
- 22
What is the function of parathyroid hormone?
Parathyroid hormone regulates calcium levels in the blood, promoting the release of calcium from bones and increasing calcium absorption in the intestines (College Board AP CED).

What is the impact of testosterone on behavior?
Testosterone is linked to increased aggression, competitiveness, and sexual behavior in males (College Board AP CED).

A student is experiencing increased stress and anxiety. Which hormone might be elevated?
Cortisol levels are likely elevated during periods of increased stress and anxiety, as it is released in response to stress (College Board AP CED).
- 25
What is the primary function of the pancreas in the endocrine system?
The primary function of the pancreas in the endocrine system is to regulate blood sugar levels by producing insulin and glucagon (College Board AP CED).
- 26
How does the endocrine system respond to long-term stress?
In response to long-term stress, the endocrine system increases the production of cortisol and other stress hormones to help the body cope (College Board AP CED).
