The Brain in Cognitive Psychology Practice Review

What is the main function of dendrites in a neuron?

• To send messages to other neurons

• To receive messages and conduct impulses toward the cell body

• To insulate the neuron

• To store neurotransmitters

What part of the neuron is responsible for transmitting messages to other neurons or muscles?

• Dendrite

• Synapse

• Myelin sheath

• Axon

What is the myelin sheath and its primary function?

• A junction between neurons

• The cell body of a neuron

• A layer of fatty cells that increases the transmission speed of neural impulses

• The site of neurotransmitter release

What occurs at the synapse?

• Neural impulses are generated

• Neurotransmitters are released and travel across the synaptic gap

• The neuron recharges

• Neural communication stops

What is action potential?

• The period when a neuron is recharging

• The resting state of a neuron

• The firing of a neuron down the axon

• The binding of neurotransmitters to receptor sites

During which phase can a neuron not fire again until it has recharged?

• Action potential

• Resting potential

• Synaptic transmission

• Refractory period

Which part of the nervous system consists of the brain and spinal cord?

• Peripheral nervous system

• Autonomic nervous system

• Central nervous system

• Somatic nervous system

Which structure connects the central nervous system to the rest of the body?

• Brainstem

• Corpus callosum

• Peripheral nervous system

• Thalamus

What is the primary function of the thalamus?

• To regulate emotions

• To relay sensory and motor signals to the cerebral cortex

• To control autonomic functions

• To connect the two hemispheres of the brain

Which part of the brain is involved in processing sound information?

• Occipital lobe

• Parietal lobe

• Temporal lobe

• Frontal lobe
