Autonomic Nervous System Flashcards
What receptors act via the Gs coupling protein
- Beta receptors
- H2 receptors
- D1receptors
- V2 receptors
What receptors act via the Gi coupling protein
- alpha2 receptors
- somatostatin
- D2 receptors
- M2 receptors
Most are twos
Location of M2 receptor on Heart
SA node, AV node, Atria
Location of Beta receptors on heart
SA node, ventricles
Receptors for Gq coupling molecule
V1, M1, M3, H1, alpha1,
Qutie HAVe 1 M&M
angiotensin 2, serotonin and opioid receptor, oxytocin, TRH, GnRH receptors
What are the organs that have their vascular smooth muscle controlled by both pns and sns
- face
- tongue
- UGS
Ganglion blockers work on the nervous system in what manner
They block the nervous system which is predominant atm
What are the muscles in the eye
Radial and constrictor muscles
Radial muscles are?
Dilator pupil that lead to mydriasis
Controlled by SNS
Circular muscles are
Muscles that lead to Miosis and accommodation
Controlled by PNS
What Ns is dominant in eye?
PNS
Which BS is dominant in Blood vessels
SNS
What are the sns functions
Glycogenolysis Lipolysis Increase HR Increase heart contractility Ejaculation Bronchodilation Increase blood flow through skeletal muscle Decrease blood flow through visceral organs Sphincter contraction Dilated pupils
