Homeostasis

Question 1

1st step in homeostasis

Answer 1

Stimulus: the change in the variable occurs (e.g. temperature, stretch in muscle)

Question 2

2nd step

Answer 2

Receptor: structure that detects the stimulus (e.g. sensory neurons, stretch receptors)

Question 3

3rd step

Answer 3

Receptor sends input info to the control center

Question 4

4th step

Answer 4

Control Center: Structure integrates input and initiates change though effectors

Question 5

5th step

Answer 5

Control Center sends output info to effectors

Question 6

6th step

Answer 6

Effector: Structure that brings about a change carries through orders

Question 7

7th step

Answer 7

Homeostasis restored

Question 8

Who are the receptors equivalent to in an office?

Answer 8

Worker who detects the problem and reports it to the boss

Question 9

Who is the control center?

Answer 9

Boss who receives info from receptor and tells the effectors what to do to combat the problem

Question 10

Who are the effectors?

Answer 10

Workers who receive boss’s plan and implement the plan to regulate

Question 11

What are the 2 categories of the homeostatic system?

Answer 11

Negative feedback loop and positive feedback loop

Question 12

Negative feedback loop:

Answer 12

moves stimulus in OPPOSITE direction; negates the problem (e.g. a hot body will try to decrease its temperature)

Question 13

Positive feedback loop:

Answer 13

moves stimulus in the SAME direction (e.g. childbirth)

Question 14

Homeostasis:

Answer 14

normal, balanced state in which a body can function in. Regulation
