Autonomic Nervous System

Sympathetic Nervous System

Activates fight or flight response S=STRESS

What does the Sympathetic Nervous System do?

• ⬆HR

• ⬆BP

• ⬆alertness

• opens airways

• decreases digestion

Neurotransmitters Involved with Sympathetic Nervous System

• epinephrine

• norepinephrine

• dopamine

Sympathetic = what kind of receptors?

adrenergic receptors

Parasympathetic Nervous System

Rest and Digest P=PEACE

Parasympathetic Nervous System promotes

• digestion

• urination

• secretion

• slowing hr

Main neurotransmitter Involved with Parasympathetic Nervous System?

Acetylcholine ACh

Parasympathetic + what kind of receptors?

cholinergic receptors

Agonist do what?

Agonists activate or stimulate aGOnist=GO

Adrenergic Agonist stimulate what?

fight or flight

Results of Adrenergic agonists:

• ⬆BP

• ⬆HR

• bronchodialation

Adrenergic Agonists are used for:

• asthma

• shock

• nasal congestion

• cardiac emergencies

Cholinergic Agonist stimulate what?

rest and digest

Cholinergic Agonists result in:

• more saliva

• more urination

• more GI movement

• pupil constriction

Adrenergic Blocker blocks what?

fight or flight

Adrenergic Blockers result in:

• decreased HR

• decreased BP

• vasodialation

Examples of Adrenergic Blockers

• beta blockers

• alpha blockers

Anticholinergic Blockers block what?

Rest and digest

Anticholinergic Blockers Result in:

“dry, hot, blind, full”

• decreased sweating

• blurred vision/ dilated pupil

• urinary retention

• constipation

Anticholinergic Blockers cause 3D effect including:

• dilation (bronchi and pupil)

• decreased GI and urinary tract

• distention (abdomen and bladder)

Alpha 1 Receptor (stimulate, used for, block)

• Alpha = arteries

• stimulates vasoconstriction, increases BP

• Used for: nasal decogestions

• block: vasodilation decrease BP

Beta 1 Receptors (stimulates and blocks)

• B1 = 1 heart

• stimulates: increased HR, increased force of constriction, increased cardiac output

• blocks: decreases HR, decreases BP, Decreases O2 demand

Beta 2 Receptors (stimulate and used for)

• B2 = two lungs, breathing

• stimulate: bronchodialation

• used for asthma

Beta 3 receptors (stimulate and used for)

B3= bladder, three = pee

• stimulate: bladder relaxation

• used for overactive bladder
