The suprarenal plexus is formed by branches from the celiac plexus, from the celiac ganglion, and from the phrenic and greater splanchnic nerves, a ganglion being formed at the point of junction with the latter nerve.
The celiac ganglia or coeliac ganglia are two large irregularly shaped masses of nerve tissue in the upper abdomen.Part of the sympathetic subdivision of the autonomic nervous system (ANS), the two celiac ganglia are the largest ganglia in the ANS, and they innervate most of the digestive tract.
The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar splanchnic nerve and aortic plexus. [1] The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them.
The adrenal medulla (Latin: medulla glandulae suprarenalis) is the inner part of the adrenal gland. [1] It is located at the center of the gland, being surrounded by the adrenal cortex. [1]
This produces methemoglobin whose paramagnetic effect results in hematomas appearing hyperintense on T1- and T2-weighted images. [14] In the chronic stage, the periphery of adrenal hematoma gradually becomes hyperintense, leaving a hypointense rim on T1- and T2-weighted images due to the hemosiderin deposition and development of a fibrous ...
A blunt injury to the celiac plexus normally resolves with rest and deep breathing. A celiac plexus block by means of fluoroscopically guided injection is sometimes used to treat intractable pain from cancers [2] such as pancreatic cancer. Such a block may be performed by pain management specialists and radiologists, with CT scans for guidance.
Venous blood is drained from the glands by the suprarenal veins, usually one for each gland: [8] The right suprarenal vein drains into the inferior vena cava. The left suprarenal vein drains into the left renal vein or the left inferior phrenic vein. The central adrenomedullary vein, in the adrenal medulla, is an unusual type of blood vessel.
The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
