A reflex pathway is the simplest pathway because it
A) involves only one synapse.
B) is evaluated and integrated by the medulla, not the cerebrum.
C) involves only two or three neurons.
D) does not involve the central nervous system in any way.
E) includes all of these.

Question

Quizplus · Accepted Answer

A reflex pathway involves only a few neurons, typically two or three, and includes a sensory neuron, an interneuron, and a motor neuron. This makes it the simplest pathway in the nervous system. Option A is partially correct, as it involves only one synapse between the sensory and motor neuron, but it doesn't take into account the interneuron. Option B is incorrect, as the medulla is part of the central nervous system. Option D is also incorrect, as reflex pathways do involve the central nervous system, just not higher centers of the brain like the cerebrum. Option E is incorrect, as option B and D are not accurate.
