Question 3

What is meant by the phrase,"all-or-none fashion" with regard to neural firing and action potentials? What is the implication of this?

Accepted Answer

For a neuron to fire,it must be stimulated at or beyond a threshold of 35mV.If the stimulation is subthreshold the neuron will not fire at all.It is not possible for a neuron to send a weaken message due to stimulation that is subthreshold.The message is sent only if the stimulation reaches or exceeds 35mV.The implications of this are that a message is not perceived as strong because of the strength of stimulation,rather it is the rate of firing and the number of neurons firing that strengthens a signal.

Question 4

Accepted Answer

A) a node of Ranvier.

B) a synapse. 
C) a neuronal break. 
D) a critical juncture.
