Baroreceptor afferents synapse at nucleus of tractus solitarius. From this nucleus vagal baroreflex (baroreflex_v) and adrenergic baroreflex (baroreflex_a) loops diverge. Baroreflex_v pathways synapse at nucleus of tractus solitarius and send efferents to sinoatrial node (SA). Baroreflex_a is mediated by connections to rostroventrolateral nucleus of medulla (RVLM) with preceding connection at caudal VLM. Sympathetic efferents from RVLM travel to intermediolateral column and thence synapse at autonomic ganglia then innervate the heart and arterioles and venules.
