In synaptic transmission, the action potential stimulates the release of:

Rachel had injections of Botox in an attempt to eliminate facial wrinkles. Botox contains minute amounts of botulin, an extremely lethal substance produced by bacteria, and works by blocking the release of a specific neurotransmitter from motor neurons, causing muscle paralysis. This neurotransmitter, found in all motor neurons, is called:

Damage to Wernicke's area in the brain:

Prozac and cocaine are very different drugs, but they achieve their effects through the same mechanism of action. What is that mechanism?

How are action potentials different in a myelinated axon and an unmyelinated axon?

Maria heard a strange banging noise just outside her bedroom window in the middle of the night. She froze in fear and her heart began to pound. Maria's heightened physical arousal involved the activation of which subdivision of the nervous system?

When a neurotransmitter communicates an inhibitory message to a postsynaptic neuron, the _____ likely to have an action potential.

One of the Focus on Neuroscience sections in the text described a study in which German neuroscientists studied people who learned to juggle. One of the findings of the study was that:

This cross-sectional drawing of the human brain depicts four structures that are key components of the limbic system. Pick the alternative that correctly labels the structures in the drawing.

Which of the following statements is FALSE?

Carlos had a stroke and although he has recovered many of his motor skills, he still has considerable difficulty with language. It is almost impossible for Carlos to produce speech, although he comprehends both written and spoken language quite well. Carlos is demonstrating characteristics of _____aphasia.

Prolactin is a hormone _____ produced by the _____.

Parkinson's disease is caused by the degeneration of neurons that produce:

Nicotine binds to acetylcholine receptor sites, stimulating skeletal muscles and causing the heart to beat more rapidly. Thus, nicotine is a(n):

Which of the following best defines neurogenesis?

For the past year, 30-year-old Kendra has experienced difficulty falling and staying asleep, and she frequently complains that she has difficulty remembering certain things, such as where she put her keys or an upcoming dentist or doctor's appointment. Kendra says she's stressed and was recently diagnosed with depression. Kendra probably has a deficiency in the neurotransmitter:
