The deep part of the cardiac plexus is situated in front of the bifurcation of the trachea (known as the carina), above the point of division of the pulmonary artery, and behind the aortic arch. It is formed by the cardiac nerves derived from the cervical ganglia of the sympathetic trunk, and the cardiac branches of the vagus and recurrent ...
Postperfusion syndrome, also known as "pumphead", is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery. Symptoms of postperfusion syndrome are subtle and include defects associated with attention, concentration, short-term memory, fine motor function, and speed of mental and motor ...
The anterior pulmonary plexus is close in proximity to the pulmonary artery. [1] The posterior pulmonary plexus is bounded by the superior edge of the pulmonary artery and the lower edge of the pulmonary vein. [1] Both lungs are innervated primarily by the posterior pulmonary plexus; it accounts for 74–77% of the total innervation. [1]
Cardiopulmonary nerves are splanchnic nerves that are postsynaptic and sympathetic. [1] They originate in cervical and upper thoracic ganglia [1] and innervate the thoracic cavity. [1] All major sympathetic cardiopulmonary nerves arise from the stellate ganglia and the caudal halves of the cervical sympathetic trunks below the level of the ...
Pectoralis minor syndrome (PMS) is a condition related to thoracic outlet syndrome (TOS) that results from the pectoralis minor muscle being too tight. [1] PMS results from the brachial plexus being compressed under the pectoralis minor [2] while TOS involves compression of the bundle above the clavicle. In most patients, the nerves are ...
The internal carotid plexus is a nerve plexus situated upon the lateral side of the internal carotid artery. It is composed of post-ganglionic sympathetic fibres which have synapsed at (i.e. have their nerve cell bodies at) the superior cervical ganglion. The plexus gives rise to the deep petrosal nerve.

The Bezold–Jarisch reflex (also called the Bezold reflex, the Jarisch-Bezold reflex or Von Bezold–Jarisch reflex [1]) involves a variety of cardiovascular and neurological processes which cause hypopnea (excessively shallow breathing or an abnormally low respiratory rate), hypotension (abnormally low blood pressure) and bradycardia (abnormally low resting heart rate) in response to noxious ...
Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance (such as from pulmonic stenosis) or high blood pressure in the lungs.
