Professor Vescovo conducts research on the relationship between the limbic system and sexual motivation. Her research interests best represents the psychological specialty known as

neurons

dendrites are branching extensions of

axon

The extension of a neuron that carries messages away from the cell body

Dendrites to the cell body to the axon

In transmitting sensory information to the brain, an electrical signal travels from the __________ of a single neuron

Myelin sheath

The speed at which a neural impulse travels is increased when the axon is encased by a(n)

action potential

A brief electrical charge that travels down the axon of a neuron is called the

synapse

Junction between a sending neuron and a receiving neuron

neurotransmitters

The chemical messengers released into the spatial junctions between neurons are called

muscular paralysis

When the release of ACh is blocked, the result is

endorphins

Opiate drugs occupy the same receptor sites as

nervous system

The body's speedy, electrochemical information system is called the

interneurons

Information travels from the spinal cord to the brain via

Interneurons/ Cerebellum/ Motor neurons/ Reticular formation

In order for you to be able to run, __________ must relay messages from your central nervous system to your leg muscles

Limbic system/ Central nervous system/ Sympathetic nervous system/ Somatic nervous system

In order for you to experience the pain of a sprained ankle, __________ must first relay messages from your ankle to your central nervous system

spinal cord

The knee-jerk reflex is controlled by interneurons is the

neural networks

Interconnected clusters of neurons in the central nervous system

endocrine system

Hormones are the chemical messengers of the

pituitary

Which endocrine gland regulates body growth

lesion

Surgical destruction of brain tissue is called a(n)

Brainstem/ Amygdala/ Hippocampus/ Corpus callosum

If your __________ is destroyed, the left side of your brain could not control the movement of your right hand

Reticular Formation

Which region of your brainstem plays a role in arousing you to a state of alertness when someone nearby mentions your name?

The most extensive regions of the brain, which enable learning and memory, are called the

plasticity

After Jim lost a finger in an industrial accident, the area of his sensory cortex devoted to receiving input from that finger gradually became very responsive to sensory input from his adjacent fingers. This best illustrates

Epileptic seizures

Neurosurgeons have severed the corpus callosum in human patients in order to reduce

Corpus callosum

Information is most quickly transmitted from one cerebral hemisphere to the other by the

Which of the following brain structures is most closely associated with the regulation of emotion

stress

The sympathetic nervous system operated (or is in primary control) during periods of

sympathetic arousal

Bill, who is anticipating an exam he will take within the hour and for which he is unprepared, will experience high levels of what?

spinal cord

You touch a hot stove and pull your hand back. This reflexive action was most likely the result of activity in your

relieve pain

Opiate drugs bind onto the same receptor sites as the body's own endorphins
