Autonomic plexuses can contain both sympathetic and parasympathetic neurons. The cardiac plexus is located near the aortic arch and the carina of the trachea. The pulmonary plexus supplies innervation to the bronchial tree. The celiac, or solar plexus, is located around the celiac trunk and contains the celiac ganglia. The solar plexus is the ...
The plexus is the characteristic form of nervous system in the coelenterates and persists with modifications in the flatworms.The nerves of the radially symmetric echinoderms also take this form, where a plexus underlies the ectoderm of these animals and deeper in the body other nerve cells form plexuses of limited extent.

Layers of the Alimentary Canal.The wall of the alimentary canal has four basic tissue layers: the mucosa, submucosa, muscularis, and serosa. The enteric nervous system in humans consists of some 500 million neurons [11] (including the various types of Dogiel cells), [1] [12] 0.5% of the number of neurons in the brain, five times as many as the one hundred million neurons in the human spinal ...
Choroid plexus epithelial cells actively transport sodium ions into the ventricles and water follows the resulting osmotic gradient. [9] The choroid plexus consists of many capillaries, separated from the ventricles by choroid epithelial cells. Fluid filters through these cells from blood to become cerebrospinal fluid.

The sympathetic trunk is a fundamental part of the sympathetic nervous system, and part of the autonomic nervous system.It allows nerve fibres to travel to spinal nerves that are superior and inferior to the one in which they originated.
But in the early 1990s, that’s exactly what one enterprising young doctor did. Helen O’Connell, an Australian urologist, took note of the many machines and mechanisms hooked up to men during medical procedures like prostate surgery — devices meant to keep surgeons as far away from nerve endings in the male sexual anatomy as possible.
