Transcript The Autonomic Nervous System

Review the structure of a reflex arc.
The Autonomic Nervous System
Basic Structure of a Visceral Reflex
What is the
advantage of a 2nd
processing center?
Compare this anatomy to that of a somatic reflex arc.
Anatomy of the Motor Output in
Sympathetic and Parasympathetic nerves
Describe the following
comparisons:
•location of pre-ganglionic
neuron cell body
•location of ganglia
•neurotransmitter released
at effectors
What neurotransmitter is
released at all Autonomic
ganglia?
Motor Neuron Pathways of the ANS
Why do Parasympathetic and Sympathetic stimulation
have opposite effects on effectors? (p. 175 in packet)
Extrinsic Influences on the Heart: an
example of ANS Dual Innervation
ANS Innervation of
visceral organs
What is the origin of
Parasympathetic nerves? …
Sympathetic nerves?
Name the neurotransmitter
released at autonomic ganglia.
Name the neurotransmitter
released from Parasympathetic
nerves at effectors.…from
Sympathetic nerves at effectors.
Does the adrenal medulla
receive dual innervation?
Explain.
Integration of the Nervous &
Endocrine Systems during Stress
Describe the actions of the hormones listed in this figure.
