Components

(generated)

Component items:

[- NE receptors of atrium muscles] (LAC.PN.SYM.SMG -> heart-symp-control): increase overall activity of heart
[- upper cardiac muscle] (LAC.PN.SYM.SCG -> heart-cardiac-upper-muscle): increase spontaneous diastonic muscle cells depolarization; increase matabolic demands of heart
[- lower cardiac muscle, middle] (LAC.PN.SYM.MCG -> heart-cardiac-lower-muscle-middle): increase heart rate (chronotropic effect) and force of cardiac contraction (inotropic effect)
[- lower cardiac muscle, stellar] (LAC.PN.SYM.STG -> heart-cardiac-lower-muscle-stellar): increase heart rate (chronotropic effect) and force of cardiac contraction (inotropic effect)
[- ACh receptors of atrium muscles] (LAC.PN.PSYM.CRG -> heart-psymp-control): decrease firing rate of SA node, slowing transmission of pacemaker impulse
Heart - baroreceptors in aorta (heart-aorta-baroreceptors -> LPC.PN.SG.NOD): increase in blood pressure signal
Heart - baroreceptors in carotid artery (heart-carotid-baroreceptors -> LPC.PN.SG.PET): increase in blood pressure signal
Heart - visceral receptors (heart-visceral -> LPC.PN.SG.UDRG): temperature and pain
