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.
The following is a list of nerves in the human body: Location ... The great plexuses of the sympathetic system; Alphabetical list. Abdominal aortic plexus;
The celiac plexus, also known as the solar plexus because of its radiating nerve fibers, [1] is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta.
The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
For the rest of the body, spinal nerves are responsible for somatosensory information. These arise from the spinal cord. Usually these arise as a web ("plexus") of interconnected nerves roots that arrange to form single nerves. These nerves control the functions of the rest of the body.
The lumbar plexus is a web of nerves (a nerve plexus) in the lumbar region of the body which forms part of the larger lumbosacral plexus.It is formed by the divisions of the first four lumbar nerves (L1-L4) and from contributions of the subcostal nerve (T12), which is the last thoracic nerve.
Efferents branches form secondary plexuses that accompany the internal iliac artery along its course. [2] They gives rise to the middle and inferior rectal plexuses , vesical plexus , deferential plexus, and prostatic plexus (in males) or uterovaginal plexus (in females).
