the ____________ drug route of drug administration is commonly used to treat small lab animals
____________ fibers send messages toward the brain
the _______________ branch of the nervous system receives sensory info and controls muscle movement
a key function of the automatic nervous system involves control of
smooth muscle, cardiac muscle, glands and "vegetative bodily processes.
the parasympathetic division of the ANS is involved in
activities that increase levels of stored energy within the body
________________ refers to the process by which drugs are absorbed, distributed within the body, and excerted from it.
A _________ section is made through the human brain parallel to the ground
which of the following is true of the relation between drug affinity and drug effects?
a drug with high affinity for a receptor wil exert an effect at a low dose.
Terms that are alike
sagittal, horizontal, transverse

identify where a particular brain region is active
administration of a drug that blocks acetycholinesterase in the brain would be expected to
increase the amount of acetycholine in the synapse
the key rationale for lesion (ablation) studies is
the change in behavior that follows a brain lesion can give important clues about a function of an ablated brain area
