Neuroanatomy Week 2 Part 2
1. autonomic nervous system is regulated by the: brainstem and hormones from the hypothal-
amus
2. which neurotransmitter does the sympathetic system use: norepinephrine
3. which neurotransmitter does the parasympathetic system use: acetylcholine
4. sympathetic nervous system originates in what levels of the spine: T1-L3
5. parasympathetic nervous system originates in the: cranial spine and sacral spine
CN: III, VII, IX, X and S2-S4
6. majority of the parasympathetic nervous system originates from which
nerve: vagas nerve CN X
7. the vagus nerve innervates the: heart
lungs
GI tract
8. vagal nerve stimulation treats: chronic pain
migraines
epilepsy
depression
1/4
, 9. the goal of vagal maneuvers is to trigger the baroreceptor reflex to treat: ar-
rhythmias and SVT
10. dysfunction of the vagus nerve leads to: increased HR, bronchodilation, decreased secretions
11. the enteric nervous system influences the: GI tract
• digestive functions of muscle contraction/relaxation, secretion/absorption, and blood flow
12. dysautonomias: disruption in the autonomic body processes
13. Horner's syndrome: •oculosympathetic paresis that affects nerves to the face and eyes. Impacts pupil
size, eye opening, and sweating
14. hyperhidrosis is excessive sweating of the face palms soles or axilla sec-
ondary to increased: cholinergic stimulation
15. excitatory function of a neurotransmitter stimulates the target cell to: perform
an action or trigger a change
16. inhibitory function of a neurotransmitter does what to the target cell: inhibits
blocks a message by preventing action potential
17. modulatory function of neurotransmitter is to: adjust communication
