Autonomic Nervous System Flashcards
(43 cards)
What are 2 anatomical components of the PNS?
ganglia and nerves
What are the 2 divisions of the afferent part of the PNS?
- Somatosensory
- Special sensory
Which division of the motor aspect of the PNS regulates blood vessels, glands and organs?
Autonomic or visceral?
Sympathetic is _______________(catabolic/anabolic)
Catabolic (increases contraction)
Where are the cell bodies located in the spinal cord?
Intermediolateral grey column
The anabolic ANS is described as ____________.
Parasympathetic
Which flow is in the sympathetic ANS?
Thoracolumbar flow
The craniosacral flow involves which cranial and sacral nerves?
Cranial: X (vagus)
Sacral: pelvic
Which neurotransmitter is in the parasympathetic ANS?
ACh
NE/E is part of which ANS division?
Sympathethic
What is the relay station outside of CNS?
A ganglion
Which axons are longer in the sympathetic ANS? (Pre/Post)
Post-ganglionic
Which axons release ACh in the sympathetic ANS?
Pre-ganglionic
What are the catecholamines?
Epinephrine and Norepinephrine
List the neurotransmitter released by pre and the post ganglionic axons in the parasympathetic NS
Both release ACh
Define the limits of the vagosympathetic trunk
C1-C4
What CN are involved in the craniosacral flow of the vagosympathetic trunk?
CN 3, 7, 9, 10
What CN are involved in the craniosacral flow of the vagosympathetic trunk?
CN 3, 7, 9, 10
List the 3 structures involved in the sympathetic NS ?
- vertebral n
- hypogastric n
- pelvic plexus
What is the type of response that ACh is related to?
Cholinergenic
What is the enzyme that breaks down ACh and where does it do it?
Acetylcholinesterase (AChE) at the synaptic cleft
List the 2 receptors that bind ACh
- Nicotinic
- Muscarinic
Describe the Nicotinic receptor (type, locations)
- somatic and ionotropic
- muscles in the NMJ
Which ACh receptor is autonomic, metabotropic and innervates glands?
Muscarinic
