Exam 7: The Nervous System: Neurons and Synapses

Ganglia are clusters of nerve cell bodies located in the peripheral nervous system.

Most synapses in the body are electrical.

Where is glycine released?

Cocaine blocks the release of dopamine,norepinephrine,and serotonin.

Degeneration of spinal motor neurons in adults may be due to a lack of ____________ factor.

The nerve is the basic structural and functional unit of the nervous system.

What is the predominant affect of stimulation of nicotinic-gated channels?

What causes presynaptic inhibition?

Atropine is an antagonist to nicotine.

An inhibitory postsynaptic potential would be produced by a neurotransmitter opening Cl^- channels.

Synaptic plasticity involves structural changes in neurons such as

If the binding of muscarine to its receptor in the heart causes the beta-gamma complex of the G-protein to bind to a K+ channel,

Serotonin is degraded in presynaptic neurons by monoamine oxidase.

Acetylcholine usually induces an excitatory postsynaptic potential when binding to ________ receptors and an inhibitory postsynaptic potential when binding to some ____________ receptors.

The __________ dopamine system may be involved in emotional reward and drug addiction.

An inactivated ion channel will respond to a strong stimulus.

Neuroleptics,which are used to treat schizophrenia,are

The minimum depolarization needed to open Na⁺ gates is called the

The most numerous of all cells of CNS nervous tissue are the

The capacity of synapses for alteration at the molecular level is termed as
