Paralytic medications exert their effect by:
A. blocking the release of epinephrine and norepinephrine from the sympathetic nervous system.
B. blocking the function of the autonomic nervous system and impeding the action of
acetylcholinesterase.
C. competitively binding to the motor neurons in the brain, thus blocking their ability to send

difficult to locate. ANSW✅✅B. the cricothyroid membrane is bordered laterally and inferiorly by
the highly vascular thyroid gland.
