PLEXUS CORONARIUS POSTERIOR Meaning and
Definition
-
The term "plexus coronarius posterior" refers to the posterior coronary plexus, which is a complex network of nerves found in the heart. It is specifically associated with the myocardium, the muscular wall of the heart. The plexus coronarius posterior is responsible for innervating and supplying the posterior part of the myocardium with nerves and blood vessels.
This plexus is formed by a collection of nerves arising mainly from the autonomic nervous system, specifically the parasympathetic and sympathetic divisions. The parasympathetic fibers originate from the vagus nerve, while the sympathetic fibers arise from the sympathetic trunk. These nerves intermingle and form a network, creating the plexus coronarius posterior.
The primary function of the plexus coronarius posterior is to regulate the cardiac activity by controlling the rate and force of the heart's contractions. The parasympathetic fibers within this plexus primarily act to slow down the heart rate, while the sympathetic fibers have the opposite effect, causing an increase in heart rate and force of contraction.
In addition to regulating cardiac activity, the plexus coronarius posterior also plays a role in transmitting pain signals. Nerves within this plexus can relay pain sensation from the posterior part of the myocardium to the brain, allowing individuals to perceive sensations such as angina or cardiac-related discomfort.
Overall, the plexus coronarius posterior is a crucial component of the heart's innervation and plays a significant role in regulating cardiac activity and transmitting pain signals.
