Autonomics of Heart
Brown/Ward 11/27
Question | Answer |
---|---|
Visceromotor system activities | Sympathetic and parasympathetic system activities |
Viscerosensory system activities | Information regarding "state of organs", non-pain and visceral pain |
Sympathetic pathway to somatic target | IML-anterior root-spinal nerve-white rami communicans-paravertebral ganglia-gray ramus-A/P rami-somatic targer (Sweat glands, arrector pili, precap.sphicter) |
Sympathetic pathway to thoracic viscera | IML-anterior root-spinal nerve-white rami communicans-paravertebral ganglia-cardiopulmonary splanchic nerve-cardiopulmonary plexus-heart by coronary arteries |
Painful stimuli pathway from heart to CNS travels along? | Sympathetics |
Painful stimuli pathway from heart to CNS | Cardiopulm plexus-cardiolpuml splanchic nerves-thoracic/cervical paravertebral ganglia-white ramus-spinal nerve-posterior root-posterior horn-synapses,decussates and travels on anterolateral system |
Non-painful stimuli pathway from heart to CNS travels along? | Parasympathetics |
Non-painful stimuli pathway from heart to CNS | Vagus nerve-caudal region of solitary nucleus |
Sympathetic action on heart and airflow | increase Heart rate and strength, increase airflow |
Parasympathetic action on heart and airflow | decrease Heart rate, decrease airflow |
Parasympathetic neurotransmitter and receptors at ganglia | Acetylcholine/Nicotinic receptor |
Parasympathetic neurotransmitter and receptors at heart | Acetylchline/Muscarinic receptor |
Sympathetic neurotransmitter and receptors at heart | Norepinephrine/ Adrenergic receptor |
Sympathetic neurotransmitter and receptors at ganglia | Acetylcholine/ Nicotinic receptor |
