Question

chapter 03 quiz: the biological bases of behavior
total points: -/20
the white, fatty substance surrounding and insulating some axons that aids in conduction of a nerve transmission is the
neurotransmitter.
myelin sheath.
basal ganglia.
synapse.
neurons communicate with each other through the use of chemical messengers called
neurotransmitters.
somas.
neurilemmas.
terminal buttons.

Explanation:

1. For the first question: The myelin sheath is a white, fatty layer that insulates axons and speeds nerve signal transmission. Neurotransmitters are chemical messengers, basal ganglia are brain structures, and synapses are gaps between neurons.
2. For the second question: Neurons use neurotransmitters, chemical messengers, to communicate across synapses. Somas are neuron cell bodies, neurilemmas are outer nerve cell layers, and terminal buttons are axon endings that release neurotransmitters.

Answer:

1. myelin sheath.
2. neurotransmitters.
