Coordination And Response Flashcards
1
Q
How do the neurones work
A
- Receptor sends electrical impulses along sensory neurone
- Electrical impulses sent along motor neurones to an effector
- Effector responds accordingly
2
Q
Reflex arc
A
Stimulus - receptor - sensory neurone - relay neurone - motor neurone - effector - response
3
Q
Cornea
A
Protects the eye and allows the eye to properly focus on light more effectively
4
Q

A
The hole that takes in light
5

7
Q
Retina
A
Connected to optic nerves that will transmit the images the eyes sees to the brain so that they can be interpreted
8
Q
Optic nerve
A
Bundle of sensory neurones that take the nervous electrical impulses to the brain
9
Q
Central nervous system is made up of
A
- Sensory, relay and motor neurones
