Explain the all-or-none principle in nerve propagation. Describe the role of the threshold in this event.
a. The all-or-none principle states that a nerve impulse is either conducted at maximum intensity or not conducted at all.
b. The threshold is the minimum stimulus strength required to initiate a nerve impulse.
c. The significance of the all-or-none principle in nerve propagation lies in ensuring the reliability and consistency of nerve signaling.
d. Both a and b
