Principles
   Autonomic nervous system (ANS) and parts of endocrine system jointly
control routine, unconscious functions and the fight-or-flight
response. Another name for the former is 1X__________ mechanisms. ANS
controls 2X__________ muscles and most 3X__________. Know the main
components and nerve pathways involved in the reflexes of the ANS:
4X__________. Most organs are innervated by both divisions of ANS, one
division 5X__________ and the other division 6__________. The
7X__________ division governs resting functions. The 8__________
division governs flight or fight. Be able to describe how a given
tissue/organ reacts to one division or another: 9__________. Know why
fight or flight responses occur: pupils dilate 10X__________; heart
rate increases 11__________, bronchioles dilate 12__________,
intestinal and salivary secretions decrease 13__________. The
sympathetic division of the ANS arises from 14X__________ segments of
the spinal column. The sympathetic 15__________ are located on both
sides of the spinal cord. 16__________ ganglia are second ganglia
found in certain parts of the sympathetic division. They lie against
the 17__________ near the organs they serve. Parasympathetic nerves
include four 18X__________ and one set of 19X__________ nerves. The
five major nerves in the parasympathetic division are 20X__________.
Of these the 21X__________ comprises 75%. Acetylcholine lasts a
22__________ and is destroyed by 23__________; norepinephrine lasts
24__________ and is 25__________ the synaptic knob. The
cardioregulator center is located in the 26X__________. It consists of
the 27X__________ centers. The 28X__________ nerve controls the
slowing of the heart. The 29X__________ nerve controls the speeding of
the heart. Pressoreceptors for the cardio-inhibitory center are
located in blood vessels 30X__________ the heart. Pressoreceptors for
the cardioaccelerator center are located in blood vessels 31X__________
the heart.
