16 Patton Ch 9 questions with correct
answers
abducens nerve - CORRECT ANSWERS-brain to external eye muscles; eye
movements
accessory nerve - CORRECT ANSWERS-brain to certain shoulder and neck muscles;
shoulder movements; turning movement of head
acetylcholine (ACh) - CORRECT ANSWERS-location: Several areas of the CNS; PNS
neuromuscular junction; ANS and visceral effectors; function: Excitatory or inhibitory;
regulates parasympathetic effectors; involved in memory
action potential - CORRECT ANSWERS-the impulse of positive charge that runs one
way down an axon
action potentials - CORRECT ANSWERS-nerve impulses
adrenal medulla - CORRECT ANSWERS-sympathetic: increases epinephrine secretion;
parasympathetic: none
, adrenergic fibers - CORRECT ANSWERS-release norepinephrine
anesthesia - CORRECT ANSWERS-loss of sensation
arachnoid mater - CORRECT ANSWERS-membrane between the dura and pia mater
resembling a cobweb with fluid in its spaces
arbor vitae - CORRECT ANSWERS-white matter tracts branching in a treelike patter in
the cerebellum "living tree"
ascending tracts - CORRECT ANSWERS-conduct impulses up the spinal cord to the
brain
astrocyte - CORRECT ANSWERS-star shaped glia; attach to neurons and to small
blood vessels, holding these structures close to each other; form a two layer structure
call the blood-brain barrier (BBB)
autonomic (visceral) effectors - CORRECT ANSWERS-tissues to which autonomic
neurons conduct impulses; visceral are cardiac muscle that makes up the wall of the
heart, smooth muscle that partially make up the walls of blood vessels and other hollow
internal organ, and glandular epithelial tissue that makes up the secreting part of a
gland
Autonomic Nervous System (ANS) - CORRECT ANSWERS-structures that regulate the
body's automatic or involuntary functions (heart rate, stomach and intestines, secretion
of chemical compounds by glands)
autonomic neurons - CORRECT ANSWERS-motor neurons that make up the ANS
basal nuclei (ganglia) - CORRECT ANSWERS-gray matter areas deep within the white
matter of the cerebral hemispheres; essential for producing automatic movements and
postures
Blood Brain Barrier (BBB) - CORRECT ANSWERS-separates the blood tissue and
nervous tissue to protect vital brain tissue from harmful chemicals that might be in the
blood
braintsem - CORRECT ANSWERS-medulla oblongata; pons; midbrain
Central Nervous System (CNS) - CORRECT ANSWERS-brain and spinal cord
cerebellum - CORRECT ANSWERS-second largest part of the human brain; under the
occipital lob of the cerebrum; folded gray matter composes the thin outer layer and
forms a large surface area of nervous connections that allow for a hug amount of
information processing; white matter tracts form most of the interior; production of
