The Nervous System Flashcards
1
Q
What is the order in which the CNS orders a response?
A
Stimulus, Receptor, Sensory Neurone, CNS, Motor Neurone, Effector, Response
2
Q
What is an effector?
A
A muscle or gland
3
Q
What is the connection between two neurones called?
A
A synapse
4
Q
Why is a reflex faster than normal responses?
A
Because you do not have to spend time thinking about the response
5
Q
How do reflexes protect the eye?
A
The light receptors in the eye detect the light and sends a message along the sensory neurone to the brain. It then travels along a relay neurone to a motor neuron which then makes the iris contract.
6
Q
What is the role of neurotransmitters in the transmission of nervous impulses?
A
The neurotransmitters set off a new electrical signal in the next neurone after transferring the signal.
