WebThe study, led by Dr. Zixi Jack Cheng, a neuro-cardiovascular scientist, was published in the Scientific Reports journal.. A team of UCF College of Medicine researchers has created a digital topographical map of the cardiac sympathetic neural network, the region that controls the body’s heart rate and its “fight-or-flight” response. These are similar to the ascending preganglionic, but in contrast, they descend to ganglia located at a more inferior level. This pathway usually involves fibers from T5-L2(3). The ascending and descending preganglionic fibers gives the sympathetic trunk the appearance of a chain with connections between the … See more Within the sympathetic trunk, preganglionic fibers usually from T1-5 spinal cord levels can ascend to other vertebral levels and synapse inside ganglia located at a more superior level. The ganglia might … See more After synapsing inside the ganglion, postganglionic fibers leave through a gray ramus communicans (grey due to absence of myelin) and re-enters the same anterior ramus, which it initially travelled through. The fibers are … See more Preganglionic fibers can also pass through the sympathetic trunk without synapsing. These fibers are usually derived from the spinal cord levels T5 … See more
