Question

a simple reflex arc involves a sensory neuron synapsing with an interneuron that synapses with a motor neuron.

select one:
true
false

what part of the brain stem is highlighted in blue?

Explanation:

Analyze the reflex arc statement

The simplest reflex arc is monosynaptic, consisting of only two neurons: a sensory neuron synapsing directly with a motor neuron (e.g., the patellar reflex). A reflex arc involving an interneuron is polysynaptic, which is more complex than the simplest possible reflex arc. Therefore, the statement is false.

Identify the highlighted brain stem region

The brain stem consists of the midbrain, pons, and medulla oblongata from superior to inferior. The highlighted blue region is the prominent, rounded middle bulge of the brain stem, which is the pons.
