Question

which of the following is not true of polysynaptic reflexes?
they have reverberating circuits.
they involve pools of interneurons.
they involve reciprocal inhibition.
they involve one muscle group.
they are intersegmental in distribution.

Explanation:

Polysynaptic reflexes involve multiple synapses. They have reverberating circuits, pools of interneurons, reciprocal inhibition, and are intersegmental in distribution. However, they do not involve just one muscle group. Instead, they often involve multiple muscle groups as part of a coordinated response.

Answer:

They involve one muscle group.
