Answer 6

Antagonistic/antagonists

Question 7

What type of response do the sympathetic and parasympathetic nervous systems do

Answer 7

Sympathetic= scared/stressed
Parasympathetic= happy/relaxed

Question 8

Answer 9

SNS= increase
PNS= decrease

Question 10

Sympathetic and parasympathetic nervous systems: where blood supply is directed

PNS= to all organs

Question 11

Sympathetic and parasympathetic nervous systems: effect on intestinal secretions and peristalsis (digestion)

Answer 11

SNS= decrease
PNS= increase

Question 12

Sympathetic and parasympathetic nervous systems: effect on bronchioles (breathing rate)

Answer 12

SNS= increase rate and depth
PNS= decrease rate and depth

Question 13

Answer 14

SNS= increase in adrenaline
PNS= decrease in adrenaline

Question 15

What are the three types of neural pathways

Answer 15

Converging
Diverging
Reverberating

Question 16

What is the converging neural pathways description

Answer 16

Impulses from several neurons travel to one neuron

Question 17

What does the meaning of converging neural pathway mean

Answer 17

This leads to increased sensitivity

Question 18

An example of the converging neural pathway

Answer 18

Neurons from rods in the retina of the eye

Question 19

What is the description of the diverging neural pathway

Answer 19

Impulses from one neuron travel to several neurons

Question 20

What does the description of the diverging neural pathway mean

Answer 20

Affects different destinations at the same time

Question 21

An example of the diverging neural pathway

Answer 21

Controlling several muscles in the hand so that the fingers can work together

Question 22

What is the description of the reverberating neural pathway

Answer 22

Neurons later in the pathway link with earlier neurons, sending impulses back through the pathway

Question 23

What does the description of the reverberating neural pathway mean

Answer 23

This allows repeated stimulation
(Enable the impulses to be recycled until it is halted)

Question 24

An example of the reverberating neural pathway

Answer 24

Breathing
