cardiac nerves造句

• These cardiac nerves go on to form cardiac and pulmonary plexuses around the heart and lungs.
• Immunohistochemistry localized the iGluRs to cardiac nerve terminals, ganglia, conducting fibers, and some myocardiocytes.
• Another nerve that comes off the vagus nerves approximately at the level of entering the thorax are the cardiac nerves.
• They innervate the heart via sympathetic cardiac nerves that increase cardiac activity and vagus ( parasympathetic ) nerves that slow cardiac activity.
• Sympathetic stimulation causes the release of the neurotransmitter norepinephrine ( also known as noradrenaline ) at the neuromuscular junction of the cardiac nerves.
• The external laryngeal nerve gives branches to pharyngeal plexus and the superior portion of the inferior pharyngeal constrictor, and communicates with the superior cardiac nerve behind the common carotid artery.
• Some few filaments from it are continued into the trunk of the vagus below the ganglion, to be distributed with the recurrent nerve and probably also with the cardiac nerves.
• On the left side, the middle cardiac nerve enters the chest between the left carotid and subclavian arteries, and joins the left half of the deep part of the cardiac plexus.
• The cardioaccelerator center also sends additional fibers, forming the cardiac nerves via sympathetic ganglia ( the cervical ganglia plus superior thoracic ganglia T1 T4 ) to both the SA and AV nodes, plus additional fibers to the atria and ventricles.
• The only cardiac nerves which do not enter into the formation of the deep part of the cardiac plexus are the superior cardiac nerve of the left sympathetic trunk, and the lower of the two superior cervical cardiac branches from the left vagus nerve, which pass to the superficial part of the plexus.
• The only cardiac nerves which do not enter into the formation of the deep part of the cardiac plexus are the superior cardiac nerve of the left sympathetic trunk, and the lower of the two superior cervical cardiac branches from the left vagus nerve, which pass to the superficial part of the plexus.
• Since resting rates are considerably less than this, it becomes evident that parasympathetic stimulation normally slows HR . The cardioaccelerator center also sends additional fibers, forming the cardiac nerves via sympathetic ganglia ( the cervical ganglia plus superior thoracic ganglia T1 T4 ) to both the SA and AV nodes, plus additional fibers to the atria and ventricles.
• Building on that concept, in 1967, the first dorsal column stimulator for pain control was demonstrated by Dr . Norm Shealy at Western Reserve Medical School, using a design adapted by Tom Mortimer, a graduate student at Case Institute of Technology, from cardiac nerve stimulators by Medtronic, Inc ., where he had a professional acquaintance who shared the circuit diagram.
