Neuronal Conduction Flashcards
1
Q
How is myelin formed?
A
By oligodendrocytes in the CNS and Schwann cells in PNS
2
Q
Node of ranvier
A
Unmyelinated nodes in between myelin sheaths
3
Q
What is the function of the myelin sheath?
A
Reduces capacitance and increases transverse resistance - movement of AP from node to node (SALTATORY CONDUCTION).
Reduces metabolic requirements due to reduced charge interaction
4
Q
AIS
A
Axon initial segment
5
Q
What is the structure of the AIS?
A
high density of voltage gated potassium and sodium gated ion channels
HODGKIN HUXLEY MODEL
6
Q
Dynamic clamp
A
Uses computer simulation to introduce artificial membrane or synaptic conductances into biological neurons and to create hybrid circuits of real and model neurons.
