Autonomic Nervous System Intro Flashcards
1
Q
What system is the ANS part of?
A
Peripheral Nervous System
-Peripheral (outside CNS)
2
Q
Name the X3 sub-divisions of ANS
A
- Sympathetic
- Parasympathetic
- Enteric-Controls GI behaviour
3
Q
What X2 neurons are required in ANS?
A
- Sensory- Visceral Efferent
- Motor- Visceral Efferent
4
Q
How would a patient describe pain associated with an organ?
A
- Dull
- NOT localised
5
Q
What is the function of Sympathetic NS?
A
- Releases Noradrenaline
- Inc. HR (> vasodilation) and Breathing Rate
- Dec. Digestive Processes
- Pupil dilation
6
Q
What is Sympathetic Outflow?
A
- In Sympathetic NS
- Exit of neurons down the spinal cord
- Then travels > Ventral Roots> Sympathetic Ganglion (Pre and Post)
7
Q
What segments have Lateral Horns?
A
-T1 and T2 parts of Intervertebral Column
8
Q
What type of innervation does both Sympathetic and Parasympathetic have?
A
-Motor Innervation (Movement)
9
Q
What is the function of the Parasympathetic System?
A
- Releases Acetylcholine
- Dec HR and Breathing Rate
- Inc. Digestive Processes
10
Q
What type of Outflow does the Parasympathetic Outflow have?
A
- Craniosacral Outflow
- Neurons begin at cranial nerves
- -Then travels > Ventral Roots> Sympathetic Ganglion (Pre and Post)
11
Q
What do Sacro Spinal and Vagus Nerves do?
A
Sacro spinal- supply lower body organs
Vagus nerves- supply upper body organs
