Action Potentials Flashcards
1
Q
What cell is the myelin sheath made of
A
Schwann cells
2
Q
Speed if conduction in an unmylinated neurone
A
0.5m/s
3
Q
Myelin sheath increase speed of transmission up to
A
100m/s
4
Q
What is it cooled when action potentials jump from one node of ranvier to the next
A
Saltatory conduction
5
Q
How does thickness of axons affect transmission speed
A
Thicke axons transmit impulses faster than thin ones as their resistance to the flow of ions is less. In small axons organelles makes less space for ions
