ap psych unit 2 test
spinal reflex ex.
a person accidentally touches a hot stove & quickly pulls their hand away, even before sensory information about the hot stove reaches the brain
if an individual has lost the ability to feel pain in their left arm, there is most likely damage to the _________________
right parietal lobe
action potential
sequence of shifts in the electrical charge of a neuron
Brain damage that leaves a person capable of understanding speech but with an impaired ability to produce speech most likely indicates injury to the ____________________
Broca's area
damage to the ______________ is most likely to be associated with difficulty in understanding language
Wernicke's area
significant damage to the reticular formation will most likely cause ______________________
a person to fall into a deep coma from which the person will be unable to awaken.
computerized axial tomography
allows the examination of living brain tissue visually WITHOUT performing surgery
somatosensory cortex
area at the front of the parietal lobes that registers and processes body touch and movement sensations
medulla
area of the brain stem that is important in controlling breathing
subdivisions within the major divisions of the human nervous system:
autonomic , sympathetic & parasympathetic
neurotransmitters that excite or inhibit s neural signal across a synapse
dopamine , norepinephrine & acetylcholine
axon terminals
branches at the end of the axon
Activation of the parasympathetic nervous system results in ________________________
decrease in heart rate.
a person with damage to the Broca's area would most likely demonstrate _____________
difficulty with speech production.
activation of the sympathetic nervous system
faster more shallow breathing & a racing heart (nervousness)
all or non response
firing of neurons
absolute refractory phase
immediately after firing, a neuron is incapable of responding to stimulation
network of structures involved in emotion, motivation & memory is the ___________________
limbic system
cerebral cortex
most active in decision making
amygdala
most associated with emotion of fear
limbic system
most closely associated with emotions
autonomic nervous system
most directly involves digesting food
postsynaptic membrane
on the dendrite or cell body of the postsynaptic neuron
occipital lobe
part of the cerebral cortex that is most responsible for the processing of visual stimuli
right occipital lobe
receives visual information from the right of BOTH retinas
what is the correct sequence of the neural chain of events set in motion by environmental stimulus?
receptors , afferent neurons , interneurons , efferent neurons , effectors
in right handed individuals spatial reasoning is predominantly a function of the _____________ of the brain
right hemisphere
pons
sleeping, waking & dreaming
reuptake
the process by which neurotransmitters are reabsorbed into the neuron after it fires
