in the parasympathetic system which of the following is the preganglionic neurotransmitter?
always acetylcholine
what parasympathetic nerve fibers supply the chest and abdomen?
cranial nerve X (aka vagus)
what parasympathetic nerve fibers supply the eyes, face, and neck are what?
cranial nerves (III, VII, IX)
true or false: every organ or tissue has a parasympathetic innervation
false
in assessing the autonomic nervous system which of the following is true for skin potentials recorded over the palm of sole of the foot?
is assesses sympathetic activity in the nerves
in assessing autonomic nervous system function which of the following is true for heart rate variability (HRV)?
its deter mined by both vagal and sympathetic innervation of the heart
in assessing autonomic nervous system function in a healthy person, which of the following may occur with a change from a supine to a standing posture?
little change in systolic pressure after three minutes
which of the following is true for the parasympathetic system?
norepinephrine is never involved as a postganglionic neurotransmitter
sympathetic nervous system or parasympathetic nervous system part of ANS that originates from the cranio-sacral portion of the nervous system
parasympathetic
sympathetic nervous system or parasympathetic nervous system post ganglionic transmitter is acetylcholine
parasympathetic
sympathetic nervous system or parasympathetic nervous system short postganglionic fibers
parasympathetic
role of the autonomic nervous system
regulates cardiac function, digestion, respiration, salvation, sweating, pupil diameter, urination, and sexual arousal
the autonomic nervous system (ANS) has what?
sensory (afferent) and motor (efferent) components
in measuring the autonomic nervous system skin potentials, which of the following is true for stimulation of the median nerve?
stimulation can be on either side
sympathetic nervous system or parasympathetic nervous system activated in fight or flight
sympathetic
sympathetic nervous system or parasympathetic nervous system long post ganglionic fibers
sympathetic
sympathetic nervous system or parasympathetic nervous system origins from the thoracic lumbar portion of the nervous system
sympathetic
sympathetic nervous system or parasympathetic nervous system post-ganglionic neurotransmitter most common norepinephrine
sympathetic
