Info

Structures Vital to Nerve Conduction• Myelin– White fatty material– Protects/insulates neuron– In the PNS• Axons myelinated by schwann cells• Each cell wraps around the axon like a jelly roll.– Neurilemma – “neuron husk”. External to themembrane– In the CNS• Oligodendrocytes myelinate nerve fiber– No neurilemma
Nerve Impulse• A nerve impulse has two properties:– Irritability: the ability to respond to astimulus and convert it into a nerveimpulse– Conductivity: the ability to transmit theimpulse to other neurons, muscles, or glands.
