Two Divisions of the ANS and their alternate names meredithmattei https://padlet.com/meredithmattei/6havo3sz89hsi122/wish/2057602284 -The Sympathetic Nervous System and the Parasympathetic Nervous System are the two divisions of the Autonomic Nervous System.
-An alternate name for the Sympathetic Nervous System is the Thoracolumbar division
https://www.britannica.com/science/sympathetic-nervous-system
-An alternate name for the Parasympathetic Nervous System is the Craniosacral division.

Neurotransmitters for each Division: meredithmattei https://padlet.com/meredithmattei/6havo3sz89hsi122/wish/2057622341 For the Sympathetic Nervous System:
-Acetylcholine (ACH) - Cholinergic
-Norepinephrine (NE) - Adrenergic
-Epinephrine (EPI) - Adrenergic
-Dopamine (DA)

For the Parasympathetic Nervous System:
-Acetylcholine (ACH)

Locations where each NT is released in each division: meredithmattei https://padlet.com/meredithmattei/6havo3sz89hsi122/wish/2059198422 Sympathetic
Acetylcholine- NT released at ganglia
Norepinephrine- NT released at postganglionic nerve endings
Epinephrine- NT produced by adrenal medulla
Dopamine- Precursor to NE
Parasympathetic
-Acetylcholine- NT at ganglia and postganglionic nerve endings

Receptors of each division and their main locations meredithmattei https://padlet.com/meredithmattei/6havo3sz89hsi122/wish/2059203052 Sympathetic
1. alpha 1
-found on glands, eyes, arteries, veins and smooth muscles
2. beta 1
-located on the heart
3. beta 2
-located on smooth muscle, coronary arteries, skeletal muscle arteries, uterus, and lungs
Parasympathetic
1. muscarinic
-found on cardiac, smooth muscle, and glands
2. nicotinic 1
-found at ganglia of parasympathetic nerves and also sympathetic nerves
3. nicotinic 2
-neuromuscular junction of skeletal muscle

-Beta 1 stimulates the heart.
Therefore there's greater increase in heart rate, force of contraction, and atrioventricular conduction
-Alpha 1 stimulates the arteries and veins, and the eye
Therefore there's vasoconstriction and contraction of the pupils
-Alpha 2 stimulates the adrenergic nerve endings
Therefore there's a decrease in norepinephrine
-Beta 2 stimulates the smooth muscles on the lungs, uterus, and skeletal blood vessels
Therefore there's bronchodilation, relaxation, and vasodilation.

Cholinergics
-ACH is released
-decreased HR, miosis, bronchoconstriction, increased digestion, urinary bladder contraction, more urination and defecation
Anticholinergics
-bind to a cholinergic receptor
-they act as a blocking drug

Sympathetic NS
Adrenergic Agonists
-stimulates alpha and beta receptors, cardiac stimulant, and bronchodilator
Adrenergic Blockers
-binds to alpha 1 receptors and blocks them
