The autonomic nervous system (ANS) is independent of our will.
It regulates fundamental states and life processes such as heart rate, BP, and body temperature
true
false
A motor nervous system that controls glands, cardiac muscle, and smooth muscle
Autonomic Nervous System
Enteric Nervous System
Somatic Nervous System
Autonomic Nervous system is also called the
Visceral motor system
glandular motor system
genitofemoral motor system
What are the primary organs of the Autonomic nervous system?
Viscera of thoracic and abdominal cavities
Some structures of body wall: cutaneous blood vessels, sweat glands, and arrector muscles
____ divisions often innervate the same target organ in the autonomic nervous system and they may have cooperative or contrasting effects.
two
one
three
What are the two divisions of the autonomic nervous system?
Fight
Flight
Sympathetic
Parasympathetic
This division of the autonomic nervous system:
•Prepares body for physical activity: exercise, trauma, arousal, competition, anger, or fear; “fight-or-flight
•Increases heart rate, BP, airflow, blood glucose levels, etc.; reduces blood flow to the skin and digestive tract
Parasympathetic
Sympathetic
This division of the autonomic nervous system:
•Calms many body functions reducing energy expenditure and assists in bodily maintenance; “resting and digesting” state
•Digestion and waste elimination
Parasympathetic
Sympathetic
Look at the image and pay attention that in the somatic motor innervation, there is a myelinated nerve fiber ending at skeletal muscles where it releases Acetylcholine.
In the Sympathetic division, there is a short myelinated preganglionic fiber, then a sympathetic ganglion and then an unmyelinated long postganglionic fiber before reaching target organ and where Noreepinephrine is released.
In the Parasympathetic division, it is one long myelinated preganglionic fiber that synapses at an unmyelinated postganglionic nerve fiber and Acetylcholine is released.
Here, baroreceptors on the internal carotid artery signal the glossopharyngeal to transmit signals to medulla. In the integrating center, a signal is sent via vagusnerve with inhibitory signals for cardiac pacemaker to lower heart rate and bp
