IUPUI Physiology Exam 3 Study Guide Questions and
Answers 2025
1. originates in the spinal cord Autonomic NS and Somatic
NS
2. targets skeletal muscle Somatic NS
3. under unconscious control Autonomic NS
4. The parasympathetic branch of the ANS... - Arises from the brainstem
and lower regions of the
spinal cord.
- Has long pre-ganglionic
fibers.
5. Which nerve has parasympathetic control of the CN X (Vagus)
heart?
6. Which tissues are only innervated by the Sympa- Liver and Kidney
thetic NS?
7. Why would the body have two different types of ACh Ditterent receptors for ACh al-
receptors? lows for ditterent actions of
ACh in ditterent tissues.
8. Poisoning of a person with mushrooms containing stimulus of target cells in-
muscarine would be expected to have what effects? nervated by post-ganglionic
parasympathetic fibers
9. a2 adrenergic receptor inhibition of insulin, stimulat-
ing the release of glucagon,
and contraction of the gas-
trointestinal tract
10. a1 adrenergic receptor smooth muscle contraction,
causes vasoconstriction

11. b1 adrenergic receptors stimulation of salivary gland
amylase secretion, increased
kidney juxtaglomerular se-
cretion of renin, lipolysis in
adipose tissue, relaxation of
the bladder detrusor muscle,
tachycardia, increased force
of heart muscle contraction,
increased automaticity of the
AV node
12. b2 adrenergic receptor smooth muscle relaxation
in uterus, decreased GI
smooth muscle motility, re-
laxation of bladder detrusor
muscle, bronchodilation, in-
creased insulin release, dila-
tion of hepatic and skeletal
muscle arteries, increased liv-
er glycogenolysis
13. b3 adrenergic receptor increased adipocyte lipolysis
increased thermogenesis, re-
laxation of bladder detrusor
muscle
14. ANS reflex Tissues can be innervated by
both branches and they usu-
ally have opposite ettects.
15. The sensory receptors of special senses are located true
within a specific area of the body.

16. Which special senses use chemoreceptors? olfaction and gustation
17. CN I olfaction
18. CN II vision
19. CN VII, IX, X gustation
20. CN VIII hearing and equilibrium
21. What happens when a person enters a brightly lit 11-cis-retinal converts to
room? 11-trans-retinal, photorecep-
tors decrease glutamate
neurotransmitter secretion,
light-on bipolar cells would
activate
22. When tip linked proteins are stretched, the hair are depolarized
cells...
23. Which of the special senses send information pri- olfaction
marily through the limbic system instead of the thal-
amus?
24. Skeletal muscle contractions with voluntary actions - movement, support, and
primary functions: positioning of our body's
skeleton
- facilitation of interperson-
al communication, including
speaking, typing, writing, fa-
cial expressions, and ges-
tures
- temp regulation
