Sympathetic and Parasympathetic are opposites for homeostasis
Sympathetic is "fight or flight" and Parasympathetic is "rest and digest" Sympathy for Angie and Brad fighting, Homer rests and digests with a parachute
Sympathetic Nervous System = Adrenergic System Adrenaline system
Adrenergic receptors are Alpha 1 & 2, Beta 1 & 2 Adrenaline receptors are the fight or flight receptors of Angie and Brad
Norepinephrine squeezes blood vessels Hormones will make you squeeze things
Adrenergic receptors use norepinephrine as neurotransmitter for responses Adrenaline receptors
Parasympathetic nervous system = Cholinergic System Homer resting and digesting with a parachute, opposite of Sympathetic fight or flight with Angie and Brad
Cholinergic receptors are Nictonic and Muscarinic
Cholinergic receptors use acetylcholine (ACh) as neurotransmitter for responses
Parasympathetic receptors cause smooth muscle contraction
Two types of muscarinic receptors: direct-acting and indirect-acting
*Adrenergic, epinephrine, norepinephrine, cholinergic, alpha, beta, neurotransmitter, nicotinc, muscarinic
