D
In a nerve pathway, the following events take place.
1) activation of muscle
2) activation of receptor
3) passage of impulses along a motor neurone
4) passage of impulses along a sensory neurone
What is the correct order of these events?
A
B
C
D
A child is frightened by a loud noise and shouts for help.
In which order are the different types of neurone involved in this response?
A
B
C
D
A finger that touches a hot object is quickly taken away from the source of heat.
What is the role of relay neurones in this response?
To carry nerve impulses within the spinal cord
To generate impulses in the receptors of the finger
To link the sense organs to the sensory neurones
To pass nerve impulses out to the neurones
Three directions in which nerve impulses can travel in the nervous system are listed.
1) away from the central nervous system
2) towards the central nervous system
3) within the central nervous system
In which direction do impulses in sensory and relay (intermediate) neurones travel?
A
B
C
D
Which of the following correctly states how the human nervous system processes information?
Stimulus --> Sensory receptors --> Central nervous system --> Nerve impulses --> Effectors --> Nerve impulses --> Response
Stimulus --> Sensory receptors --> Nerve impulses --> Central nervous system --> Nerve impulses --> Effectors --> Response
Stimulus --> Central nervous system --> Nerve impulses --> Sensory receptors --> Nerve impulses --> Effectors --> Response
Sensory receptors --> Stimulus --> Nerve impulses --> Central nervous system --> Nerve impulses --> Effectors --> Response
