Aferen\u0163ele specifice transmit centrilor cardiovasonotori informa\u0163ii asupra varia\u0163iilor parametrilor hemodinamici controla\u0163i ( presiune sanguin\u0103, presiuni par\u0163iale ale gazelor respiratorii, reac\u0163ia s\u00e2ngelui, osmolaritate) care se transmit ascendent pe c\u0103i vegetative parasimpatice \u015fi simpatice.<\/span><\/div>\n

Fibrele care transmit aceste in forma\u0163ii au pericarionii \u00een ganglioni senzitivi ai vagului (jugular \u015fi plexiform). Prelungirile centrale ale acestor neuroni pseudounipolari fac sinaps\u0103 cu neuronii din ariile bulbopontine cardionhibitoare \u015fi vasodilatatoare. Prelungirile periferice coboar\u0103 prin trunchiul vagului spre inim\u0103 \u015fi vase stabilind conexiuni cu baroreceptorii \u015fi chemoreceptorii aortici \u015fi sinocarotidieni.<\/span><\/div>\n
 Aferen\u0163ele de la nivelul baro- \u015fi chemoreceptorilor sunt transmise prin nervul sinocarotidian (sau sinusal descris de Hering) ariei cardioinhibitoare \u015fi vasodilatatoare din forma\u0163iunea reticulat\u0103 bulbopontin\u0103 iar prelungirile periferice ajung la bifurca\u0163ia carotidei termin\u00e2ndu-se la nivelul glomusului carotidian a II-a zon\u0103 reflexogen\u0103 principal\u0103 arterial\u0103 implicat\u0103 \u00een reglarea activit\u0103\u0163ii cardiace.<\/span><\/div>\n
Aferen\u0163a simpatic\u0103 particip\u0103 la realizarea reflexelor cardiace cardioacceleratoare \u015fi vasopresoare \u015fi de asemenea la sensibilitatea cardiac\u0103 con\u015ftient\u0103.  Fibrele au originea \u00een neuronii din ganglionii paravertebrali cervicodorsali.<\/span><\/div>\n
