nervous system Flashcards
1
Q
CNS coordinating a response
A
- stimulus
- receptor
- sensory neurone
- CNS
- motor neurone
- effector (muscle/gland)
- response
2
Q
relfex arc
A
- stimulus
- receptor
- sensory neurone
- relay neurone
- motor neurone
- effector (muscle/gland)
- response
3
Q
neurone structure
A
- electrical impulses - passed along axon
- dendrites - branched endings to connect to many other neurones
- long to speed up impulse (connecting another neurone slows the process down)
- connects to another neurone via synapse - impulse triggers transmitter chemicals, diffuses along gap to next neurone, triggering impulse
4
Q
sensory neurone
A
- short axon
- long dendron
- cell body along axon
5
Q
motor neurone
A
- myelin (fatty) sheet surrounds axon
- cell body at beginning
- long axon
