sac 3 homestatis

Question 1

what role does the receptor play in maintaining homeostasis

Answer 1

their job is to detect the change in the stimulus and send a message to the control center

Question 2

what role does the control center in maintaining homeostasis

Answer 2

receives the message and coordinates a response. Sends an output message to an effector

Question 3

what role does the effector in maintaining homeostasis

Answer 3

effectors (muscles and glands) respond to the output from the control center

Question 4

homeostasis

Answer 4

homeostasis is a relatively constant psychological state of the body despite changes in the external enviroment

Question 5

what are the components of the stimulus-response model

Answer 5

stimulus, receptor, control center, effector and response

Question 6

what happens in the receptor stage

Answer 6

a structure that detects change sends signals to the control center

Question 7

what happens in the control center

Answer 7

the central nervous system evaluates the stimulus and sends to effector for any corrections

Question 8

what happens in the effector stage

Answer 8

the structure adjusts the control center signal to make it correct

Question 9

what is the negative feedback

Answer 9

a control system that maintains the body internal environment at a relatively steady state

Question 10

what is positive feedback?

Answer 10

a mechanism that increase response in order to achieve a particular result

Question 11

the endocrine system

Answer 11

made up of ductless glands, which secrete hormones into the blood. These participate in feedback loops and regulate internal functions.

Question 12

endocrine glands

Answer 12

scattered widely throughout the body and their positioning does not necessarily reflect the lcation

Question 13

hormones defintion

Answer 13

chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, skins, muscles and organs

Question 14

endocrine glands ect

Answer 14

endocrine glands are not considered as a part of the endocrine system as they do not produce hormones

Answer 15

if the hormone matches the receptor it can target a cell

Question 16

insulin

Answer 16

hormone that acts to increase the uptake of glucose from the blood by body cells

Question 17

glucagon

Answer 17

hormone that acts on liver cells resulting in increased release of glucose from the liver cells into the bloostream

Question 18

stimulus-response model regarding blood glucose level

Answer 18

stimulus receptor control center response effector

Question 19

stimulus role in blood glucose level

Answer 19

blood glucose

Question 20

receptor role in blood glucose level

Answer 20

alpha cells in the pancreas

Question 21

control center role in blood glucose level

Answer 21

alpha cells of the pancreas secrete the hormone glucagon

Question 22

effector role in blood glucose level

Answer 22

live cells and body cells

Question 23

response role in blood glucose level

Answer 23

in blood glucose by the release of glucose into the blood from the liver

Question 24

regulation of body temp in animals ( stimulous)

Answer 24

the body temperature is below normal

Question 25

regulation of body temp in animals (receptor)

Answer 25

decrease detected by thermoreceptors in skin, organs and hypothalamus of the brain

Question 26

regulation in body temp in animals (control center)

Answer 26

hypothalamus sends signals via never and hormonal systems to effectors

Question 27

regulation in body temp in animals (effector)

Answer 27

blood vessels in the skin and skeletal muscles

Question 28

regulation of body temp in animals (response)

Answer 28

reduced blood flow in skin vessels and shivering occurs

Question 29

thermoreceptors

Answer 29

receptors that detect changes in temperature such as cold-sensitive nerve endings in your skin and groups of temperature sensitive nerve cells

Question 30

explain how negative feedback is involved in the regulation of body temp

Answer 30

it tries and balances everything out fo example sweating is negative feedback because you are hot and need to release the heat

Question 31

thyroid and theromoregualtion

Answer 31

hormones regulate many aspects of metabolism over or under production of hormones can affect metbaloic aspects

Question 32

how is T4 involved in temperature regulation

Answer 32

t4 speed up metabolic activity in cells that increase in metabolic activity also results in the production of heat
