[Maximum number: 1]

State one difference between nervous and hormonal control systems.

Question 3(f)

[Maximum number: 1]

State one difference between nervous and hormonal control systems.

Question 3(c)

[Maximum number: 2]

Fig. 3.1 is a diagram of the junction between two neurones in a healthy person.
Fig. 3.2 is a diagram of the junction between the same two neurones in a person who has Parkinson's disease. This disease affects the nervous system.

Body temperature is controlled by both hormones and nerves.

Explain how co-ordination by hormones differs from co-ordination by nerves.

Question 4(d)

[Maximum number: 4]

Explain the advantages of coordinating the response to a dangerous situation using both the nervous system and the endocrine system.

Question 25

[Maximum number: 1]

Hormones and the nervous system both control our bodies.
Which statement about the control provided by our hormones is correct?

A

fast response and long lasting

B

fast response and short lived

C

slow response and long lasting

D

slow response and short lived

Question 25

[Maximum number: 1]

Compared to the hormonal system, the responses of the nervous system are

A

faster and of longer-duration.

B

faster and of shorter-duration.

C

slower and of longer-duration.

D

slower and of shorter-duration.

Question 26

[Maximum number: 1]

Hormones and the nervous system both control our bodies.
Which statement about the control provided by our hormones is correct?

A

fast response and long lasting

B

fast response and short lived

C

slow response and long lasting

D

slow response and short lived

Question 4(e)

[Maximum number: 1]

A neurone is a type of specialised animal cell.

Nerves and hormones coordinate the functions of the body.

Suggest why blinking of the eyes is coordinated by nerves and not hormones.
