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
