The resistor-capacitor network model we developed in Lecture
(see figure below where it is shown only for the myelinated case)
for the transmission of signals in nerve axons can actually be
applied to both unmyelinated and myelinated nerve cells to estimate
the propagation speed of a nerve impulse. In the unmyelinated case
the 6-7 nm thick plasma membrane (the lipid bilayer) acts both as a
(very thin) dielectric layer forming a capacitor between the inside
of the axon and the...

An axon is a long, slender projection of a nerve cell, or neuron e , that typically conducts electrical impulses e away from the neuron's cell body e . Capacitance (C) is the ability of a system to store an electric charge. In this activity, you'll use information given about these fascinating structures to calculate the capacitance of an axon.

Nerve impulses are initiated at the input end of a nerve cell, travel along a relatively long axon (cable), and then cause an effect at the output end of the cell-for example, the initiation of a muscle contraction in a muscle cell. The nerve impulse is initiated by a stimulus that lowers the potential difference from outside the cell to inside from its normal – 70 mV to about -50 mV. A potential difference across two parts of the body...

The membrane of
the axon of a nerve cell is a thin cylindrical shell of radius r-
10 m, length L 0.48 m, and thickness d 108 m. The membrane has a
positive charge on one side and a negative charge on the other, and
acts as a parallel plate capacitor of area A 2arL and separation d.
Its dielectric constant is about 7.

#2 please
In this part, we will explore electrostatics as it relates to the nerve cell, a critical electrostatic device for almost all life. We will use a rather simplified picture of the nerve cell, and treat it as a parallel plate capacitor. Although oversimplified, this model does correctly describe the underlying physics. As shown in the diagram below, the nerve cell is a fluid-filled tube (the axon) that is surrounded by another fluid. The nerve cell wall (membrane) separates...
