Which of the following statement is true about neurons?
a) Neurons generally employ a passive signaling mechanism in which a signal is not amplified along the way.
b) Axons of many vertebrate neurons are insulated by myelin sheaths.
c) While axons typically receive signals, dendrites transmit them.
d) An action potential carries a signal from one end of the neuron to another at speeds of about 100 millimeters per second.
Homework Answers
Answer:- Axons of many vertebrates are insulated by myelin sheaths because they act as a electric insulator and avoid leaking of current which lead to increase in the conductance of action potential.
Hence option B is correct.
