Why is the speed of conduction through a reflex arc slower than the speed of conduction of an action potential along an axon?
A) Transmission between neurons at synapses is slower than along axons.
B) The longer an axon, the slower its velocity.
C) Interneurons have thicker axons than other neurons.
D) There are greater amounts of myelin involved in the reflex arc.

The transmission between neurons at synapses is slower than along axons because it involves the release and diffusion of neurotransmitters, which takes time. In a reflex arc, there are multiple synapses involved, which can lead to further delays in transmission.
