The splanchnic nerves are paired visceral nerves (nerves that contribute to the supply of the internal organs), carrying fibers of the autonomic nervous system (visceral efferent fibers) as well as sensory fibers from the organs (visceral afferent fibers). All splanchnic nerves carry sympathetic nerve fibers except for the pelvic splanchnic nerves, which carry parasympathetic fibers….
The suprascapular nerve is the lateral branch of the superior trunk given by the brachial plexus. It receives nerve fibers that originate in the nerve roots C5 & C6[ & sometimes C4]. The suprascapular nerve is a mixed nerve, meaning that it gives both sensory & motor supply to the suprascapular region. The main function…
Introduction The intercostal nerves originate in segments from the anterior/ventral rami of thoracic spinal nerves T1 to T11. The term ’intercostal’ mention to their course in the intercostal space, in which they run alongside intercostal vessels. The anterior rami of the most inferior thoracic spinal nerve (T12) give rise to the subcostal nerve which runs…
Introduction The genitofemoral nerve is a branch of the lumbar plexus that contain fibers from the anterior rami of spinal nerves L1 and L2. The nerve arises in the substance of the psoas major muscle and descends retroperitoneally proceeding to the inguinal ligament. The genitofemoral nerve ends by giving off two terminal branches: the femoral…
Medial pectoral nerve The medial pectoral nerve, this is also known as the medial anterior thoracic nerve, is a branch of the medial cord of the brachial plexus. alongside originating, the nerve travels together with the axillary artery & vein, being located between them.The medial pectoral nerve is lonely a motor nerve. Its main function…
Introduction Ilioinguinal nerve The ilioinguinal nerve is also one of the branches of the lumbar plexus. It is a mixed type of nerve that rises as a continuation of the inferior branch of the anterior (ventral) ramus of spinal nerve L1. The function of the ilioinguinal nerve is to give the sensory supply to the…
List of nerves – There are 12 cranial nerves, and this list is further classified into a list of spinal nerves, a list of nerves that travels into the upper limb, lower limb, trunk, and organs. What are nerves? Nerves are like cables that conduct electrical impulses between the brain & the rest of the…
Overview The saphenous nerve is a sensory nerve that presents deep within the leg. It’s part of the peripheral nervous system, which helps the brain interpret, or “feel,” stimuli from the body & the environment. The function of the saphenous nerve the saphenous nerve is a sensory nerve that carries information about what the leg…
Introduction The zygomatic nerve is the branch of the maxillary nerve, which by itself is a branch of the trigeminal nerve (CN V). It runs from the orbit & splits into the zygomaticotemporal & the zygomaticofacial nerve. It gives sensory supply to the skin over the zygomatic bone & the temporal bone. either It also…
Description Sacral plexus with Pudendal nerveThe term ‘Pudendal’ comes from the Latin pudenda, meaning “external genitals”, derived from pudendum, meaning “parts to be ashamed of”. The pudendal nerve is the main nerve of the perineum, pelvic floor muscles & external genitalia. Benjamin Alcock first described it in 1836 while researching the internal pudendal artery’s path…
