Question

Changing the thickness of the myelin sheath surrounding an axon changes its capacitance and thus the conduction speed. A myelinated nerve fiber has a conduction speed of 53 m/s . If the spacing between nodes is 1.0 mm and the resistance of segments between nodes is 26 MΩ , what is the capacitance of each segment?

Answer 1

For a myelinated nerve fiber has a conduction speed of 53 m/s, the capacitance of each segment is mathematically given as

C=8.2*10^{-13}F

What is the capacitance of each segment?

Generally, the equation for the Constant  is mathematically given as

t=RC

Therefore

t=V/d

Hence

C=V/Rd

C=1.2*1)^-3/26*10^6*56

C=8.2*10^{-13}

In conclusion, the capacitance

C=8.2*10^{-13}F
