visceral sensory division
17. Neurotransmitters can be either excitatory or inhibitory depending upon the receptor present on the postsynaptic neuron.
True
False
18. During depolarization, the membrane potential becomes more positive.
True
False
19. What is NOT a function of the nervous system?
direct long-term functions such as growth
control effectors
sense the internal and external environments
integrate sensory information
20. Cognition is best described as:
the ability to comprehend and produce words.
encoding and storing learned information in our neural circuitry.
recognizing, processing, planning, and responding to stimuli.
a reversible and normal suspension of consciousness.
21. In contrast to the nervous system, the endocrine system accomplishes homeostasis by:
producing an immediate effect in target cells.
releasing hormones into the blood that regulate the functions of other cells.
sending action potentials that excite or inhibit target cells.
controlling the activities of the autonomic nervous system (ANS).
