Autonomic Nervous System Flashcards
What Does The Nervous System Divide Into?
Central Nervous System and Peripheral Nervous System
What Does the Peripheral Nervous System Divide Into?
Autonomic and Somtatic
What is Autonomic System Divide Into?
Sympathetic and Parasympathetic Nervous System
What system is considered to be as “Flight or Fight” response?
Sympathetic Nervous System
What system is considered to be as “Rest and Digest” response?
Parasympathetic Nervous System
List examples of Sympathetic stimulation
- Increased Heart Rate
- Dilated Pupils
- Bronchiolar Dilation
- Increased Blood Pressure
- Constriction of Blood Vessels
- Increased Glucose Levels
List examples of Parasympathetic stimulation
- Reduced Heart Rate
- Constricted Pupils
- Salivation
- Increased Gastric Motility
- Bronchoconstriction
What is known as the “Chemical Messengers” of the body?
Neurotransmitters
Where are the neurotransmitters released?
Synaptic Cleft / Synapse
How do nerve impulses occur?
Axon
Synaptic Cleft
Dendrite
One nerve cell to the other
What NEUROTRANSMITTER and RECEPTOR is from the PARASYMPATHETIC division?

What acts as an inhibitory for the sympathetic system?
Beta
Where are Beta 1 Receptors Located?
in the Heart
cause an increased force of contraction
Where are Beta 2 Receptors Located?
in the Vascular and Non Vascular smooth muscle
cause relaxation
