What part of the nervous system are we most likely to find oligodendrocytes?

What region of the brain is involved in the formation of new memories?

What neurotransmitter is primarily released from somatic neurons onto skeletal muscles to initiate skeletal muscle contraction?

An experimental drug was found to cause vascular smooth muscle contraction due to directly binding to receptors in I vessels in a laboratory experiment. What is the most likely mechanism of action of this drug?

A graduate student studying the effects of adrenergic and cholinergic drugs was testing 5 novel compounds. Each had an effect on the synaptic concentration of either acetylcholine or norepinephrine. Which drug would result in an increase in the concentration of a neurotransmitter?

What receptor is located in the postganglionic neurons in both sympathetic and parasympathetic ganglia?

A patient with seasonal allergies had been self-medicating with an over-the-counter antihistamine. She had heard that the medication is "safe" and took a handful to try and improve her symptoms. She later presented with symptoms Of dry mouth and skin. constipation and various other symptoms. What receptors are most likely being antagonized to cause these symptoms?

What cranial nerve has parasympathetic fibers important in autonomic reflexes such as managing blood pressure?

What will happen to the excitability of a cell when a positive ion, such as potassium, leaves?

What type of ion channel is primarily responsible for conducting action potentials down axons?

If a nicotinic acetylcholine receptor in a muscle cell is continuously stimulated. What is the most likely result after prolonged exposure?

What is the role of the S4 region of a voltage gated sodium channel?

A patient has a neurological disorder involving demyelination of neurons of the central nervous System. What disease does the patient most likely have?

A novel drug works by shortening the time that voltage gated potassium channels are open. What impact Will this most likely have on action potentials?

What is the most likely effect of activating a ligand-gated chloride channel such as a GABA-A receptor?
