Exam 7: The Nervous System: Neurons and Synapses

The blood-brain barrier results mostly from the action of __________,a type of glial cell.

Action potentials frequency encodes stimulus intensity.

Which of the following is NOT a function of neurotrophins?

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

Which of the following is NOT a structural classification of neurons?

What structure is found around PNS axons that is NOT found around CNS axons?

Catecholamines activate postsynaptic cells by

All axons in the PNS are surrounded by Schwann cells.

Addictive drugs,as well as nicotine,activate dopamine release in the

Acetylcholine can induce hyperpolarization by

Muscarinic ACh receptors are found in all of the following locations EXCEPT

Excitable cells are incapable of maintaining a constant resting membrane potential.

Axons require ATP to produce an action potential.

What amino acid are dopamine,norepinephrine,and epinephrine derived from?

The ability of a neuron to transmit charge through its cytoplasm is called cable properties and is very

Release of ACh at parasympathetic effectors is always stimulatory.

Axonal regeneration is inhibited by

Mutation of the N-methyl-D-aspartate (NMDA)receptor would affect the ability of ____________ to regulate neural function.

An EPSP is conducted decrementally to the axon hillock,where voltage-gated Na+ and K+ channels are opened to created an action potential in the first segment of the axon.

Both neurons and neuroglia will easily divide by mitosis.
