Autonomic Nervous System Flashcards
1
Q
What 3 Visceral functions does the Autonomic Nervous System control?
A
- Circulation
- Digestion
- Excretion
2
Q
What Do the Autonomic Nervous System nerves control?
A
- Smooth muscle
- Cardiac Muscle
- Secretory Glands
3
Q
What Secretory Glands do ANS neves control? (APSS)
A
- Adrenal Medulla
- Pancreatic Islets
- Salivary Glands
- Sweat
4
Q
How do ANS Nerves control Cardiac Muscle?
A
- Controls Heart rate
- Controls Contractile force
5
Q
What are the 3 Divisions of the ANS?
A
- Sympathetic (SNS)
- Parasympathetic (PNS)
- Homeostasis - When SNS and PNS are Dynamically balanced
6
Q
Where is the Adrenal Gland located?
A
On top of the kidneys
7
Q
What are Receptors?
A
Protein structures that receive and transduce signals
8
Q
What are 2 examples of receptors?
A
- Ligand-gated ion channel-linked (ionotropic) receptors
- G protein-linked (metabotropic ) receptors
9
Q
What are Ionotropic Receptors?
A
- Binding site and cell combined
- No second messenger
- Rapid response
10
Q
What are Metabotropic Receptors?
A
- Binding site not combined with a channel
- Has 2nd messenger
- Slower response
11
Q
Give 1 example of an Organ that has input from both PNS and SNS
A
- Bronchial Smooth Muscle
12
Q
List 9 Patadympathetic indications.
A
- pupil contstriction
- Decreased Heart rate
- Bronchoconstriction
- increased salivation
- Increased digestion
- Increased urination
- Increased defecation
- Stimulation of insulin secretion
- usually dominant
13
Q
List 11 Sympathetic indications.
A
- Pupil dilation
- Increased Heart rate
- Bronchodilation
- Decreased salivation
- Decreased digestion
- Decreased urination
- Decreased defecation
- Vasoconstriction near non-essential organs
- Vasodilation near muscles
- Inhibition of insulin secretion
- Glycogenolysis
14
Q
Is Fight or Flight response Sympathetic or Parasympathetic
A
Sympathetic
15
Q
Is Rest and Digest response Sympathetic or Parasympathetic
A
