Flashcards in Chapter 1: The Study of Behavioral Endocrinology Deck (23):
1

behavioral endocrinology

The study of the interactions among hormones, brain & behavior

2

hormones

An organic chemical messenger released from the endocrine cells that travels through the blood system to interact with cells at some distance away & causes a biological response

3

endocrine glands

A ductless gland from which hormones are released into the blood system in response to specific physiological signals

4

psychology

the scientific study of emotion, cognition, and behavior

5

testes

the male gonads, which produce steroid hormones & sperm

6

castration

the surgical removal of the gonads

7

eunuch

a man who has been castrated

8

neurotransmitters

chemical messengers that communicate between nerve cells (neurons)

9

cytokine

a protein chemical messenger that evokes the proliferation of other cells, especially in the immune system

10

receptor

a chemical structure on the cell surface or inside the cell that has an affinity for a specific chemical configuration of a hormone, neurotransmitter, or other chemical compound

11

target cells

a cell that has specific receptors for, and is affected by, a particular chemical messenger

12

effectors

the output system, in biology, usually refers to muscles

13

levels of analysis

the set of overlapping and interacting questions about behavior that span different types of approaches, including immediate causation, development, evolution and adaptive function

14

immediate causation

the physiological mechanisms underlying behavior

15

development

the role of experience in individual behavior

16

evolutionary approaches

the perspective(s) adopted by biologists who assume that evolutionary processes are central to issues in ecology, systematics, and behavior

17

adaptive function

the role of any structural, physiological, or behavioral processes that increases an individual's fitness to survive and reproduce as compared with other conspecifics

18

ablation

removal, especially by cutting

19

lesion

damage to an area, such as a brain region, that is caused by accident, disease, or experimental procedure

20

agonist

a chemical substance that binds to receptors for a hormone or neurotransmitter and causes a biological response that is indistinguishable from the response elicited by the natural hormone or neurotransmitter

21

antagonist

a chemical substance that binds to receptors for a hormone or neurotransmitter, but does not cause a biological response

22

adipose

connective tissue in which fat is stored

23

leptin

a protein hormone secreted by fat cells that may communicate information to the brain about body fat content
