A mugger steals your wallet causing all of the following to happen EXCEPT ________.
A) increased rate and force of heartbeat
B) inability to read close-up print
C) increased glucose uptake to the liver from blood
D) increased metabolic rate - CORRECT ANSWER>>>>increased glucose uptake to
the liver from blood
Which of the following is mismatched?
A) gallbladder contracts to expel bile; parasympathetic
B) bronchiole dilation in lungs; sympathetic
C) penis ejaculation; sympathetic
D) promotes urination; sympathetic - CORRECT ANSWER>>>>promotes urination;
sympathetic
Which type of drug would be useful in dilating the pupils for an examination of the
retina?
A) beta-3 receptor mimic
B) muscarinic receptor inhibitor

Which target organ receives dual innervation?
A) kidney
B) sweat glands
, C) small intestine
D) coronary blood vessels - CORRECT ANSWER>>>>small intestine
Which of the following is mismatched?
A) sympathetic preganglionic fibers; release ACh
B) parasympathetic preganglionic fibers; release ACh
C) sympathetic postganglionic fibers; release NE
D) parasympathetic postganglionic fibers; release NE - CORRECT
ANSWER>>>>parasympathetic postganglionic fibers; release NE
Explain the concept of dual innervation in the autonomic nervous system. Provide two
examples. - CORRECT ANSWER>>>>Dual innervation comes from both divisions
of the autonomic nervous system innervating the same effectors and causing an
opposite response on them.
ex:
-parasympathetic innervation causes the heart to slow its heartrate, while
sympathetic innervation causes the heart to speed up heart rate.
-smooth muscles that control the pupil- sympathetic division causes the
contraction of the radial muscles causing dilation; while, the parasympathetic
division causes the contraction of the circular muscles which causes the pupil to
constrict
What studies have suggested that the ANS can also be subject to voluntary controls? -
CORRECT ANSWER>>>>-Experimentation involving meditation and biofeedback
have indicated that this is possible.
-Meditating yogis have indicated major physiological states, while biofeedback
training suggests that we can alter certain processes such as heart rate, blood
pressure, and muscle tone
Most newborns ________.
A) are myopic
B) often use only one eye at a time
C) see in tones of red and green only
D) cry with copious tears - CORRECT ANSWER>>>>often use only one eye at a time
The blind spot of the eye is caused by ________. - CORRECT ANSWER>>>>there are
no photoreceptors where the optic nerve leaves the eye
The first vestiges of eyes in the embryo are called ________. - CORRECT
ANSWER>>>>optic vesicles
Which pairing of terms is incorrectly related?
A) frequency of sound waves: loudness of the sound
B) quality of a sound : frequency of the sound
C) amplitude of a sound: intensity of the sound
