Adrenergic System]]> 2020-09-23 01:12:42 UTC https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770495061 Neurotransmitters and Locations: colbygonzales https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770499456 1.) Acetylcholine (ACH)- it is released at ganglia from the presynaptic nerve.
2.) Dopamine (DA)- it is found in the CNS and is in the brain specifically. 
3.) Epinephrine (EPI)- it is released at the adrenal medulla.
4.) Norepinephrine (NE)- it is released at the post ganglia nerve endings; also released at the adrenal medulla and post synaptic neurons.]]> 2020-09-23 01:14:56 UTC https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770499456 Parasympathetic Nervous System (PSNS): colbygonzales https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770506561 -Acetylcholine (ACH) is released by the ganglia from the presynaptic nerves and the post ganglionic nerve endings.]]> 2020-09-23 01:18:12 UTC https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770506561 Receptors and Location: colbygonzales https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770510377 Sympathetic Nervous System (SNS)
-Adrenergic Receptors 
* -alpha 1 
location: glands, smooth muscles, eyes, veins, and most arteries; stimulated by EPI and NE.
* -beta 1
location: the heart; stimulated by EPI and NE.
* -beta 2
location: uterus, lungs, skeletal muscle arteries, and smooth muscle; can be stimulated by EPI only.

-Adrenal Medulla; it releases EPI.
-Arteries and vasoconstriction.
-Skeletal muscle arteries/coronary can also dilate. 
-Heart; +Chronotrope (heart rate), +Inotrope (contractility), and +Dromotrope (AV conduction).
-Eye: Mydriasis (dilation of the pupil).
-Lungs: Bronchodilation.
-GI: Secretions/Motility are both decreased.
Urinary Sphincter: Contraction of the smooth muscle.
Urinary Bladder: Relaxation of the smooth muscle.]]> 2020-09-23 01:23:53 UTC https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770518808 Drug Classifications (Drug Name, MOA, and Receptors): colbygonzales https://padlet.com/colbygonzales/ji4m2xxso2wluhb7/wish/770535842 Sympathomimetics- drugs that mimic the sympathetic system.
*Adrenergics-Agonists*
Alpha 1 Adrenergic Agonists
-increase blood pressure.
-vasoconstrictions.
-stimulates the alpha 1 receptor.
-decongest effect within the nasal passageway.
-smooth muscle contraction.
Drugs:
-ephedrine and phenylephrine (Neo-Synephrine)
Adrenergic Agonist
