The Central Nervous Systems (CNS) Coordinates Information Flashcards
1
Q
What is the nervous system made up of?
A
All the neurones (nerve cells) in your body
2
Q
What are the main three types of neurone?
A
Sensory, relay and motor
3
Q
What does the Central Nervous System consist of?
A
The brain and spinal cord only
4
Q
- What do receptors do in a sense organ when they detect a stimulus?
A
They send electrical impulses along sensory neurones to the CNS
5
Q
- What does the CNS do after?
A
It the sends electrical impulses to an effector along a motor neurone. The effector then responds accordingly
6
Q
What is the job of the CNS?
A
To coordinate the response
7
Q
What do coordinated responses always need?
A
A stimulus, receptor and an effector
8
Q
What happens because neurones transmit information using high speed electrical impulses?
A
The nervous system is able to bring about very rapid responses
