The Two Main Neurotransmitters Of The Autonomic Nervous System Are
Question: acetylcholine (ACH)
Answer: Primary transmitter of the ANS. (one of 2)
-Primary location: Synapses throughout the CNS; preganglionic neurons ending in the ganglia in both the symathetic and parasympathetic nercous systems (nicotonic); postganglionic neurons ending in neuroeffector target tissues in the parasympathetic nervous system (muscarinic) (p.140-142)
Question: acetylcholinesterase (AchE)
Answer: Enzyme that resides in the synaptic cleft and catalyzes the destruction of Ach. [**The suffix “erase” can be thought of as “wiping out” the Ach]
(p.143-143)
Question: Adrenergic
Answer: Receptors at the ends of postganglionic sympathetic neurons.
(p.144)
Question: autonomic nervous system (ANS)
Answer: Part of the motor division of the peripheral nervous system that provides for the involuntary control of vital functions of the cardiovascular, digestive, respiratory, and genitourinary systems
Question: THREE MAIN ACTIVITIES OF THE ANS
Answer: 1.) contraction of smooth muscle of the bronchi, blood vessels, GI tract, eye, and genitourinary tract
2.) contraction of cardiac muscle
3.) secretion of salivary, sweat, gastric, and bronchial glands
