a rare variation of the human median nerve direction

A Rare Bilateral Variation in the Formation of Median Nerve

The median nerve is formed by fusion of lateral (C5-C7) and medial (C8, T1) cords from the brachial plexus. Bilateral variations in the formation of median nerve are very rare. One of such variations was observed during the dissection of the upper limb of approximately a 30-35-year-old man cadaver, according to Grant s method. The median nerve was formed by the union of three roots on both side...

Variation in median nerve nutritional artery at the distal end of forearm: case report

Background: The median nerve is one of the most important branches of the brachial plexus. Due to the role of the median nerve in sensory and motor innervation of the forearm and hand in the upper limbs, its blood supply is very important. Awareness of variations in the blood supply pattern to this nerve reduces the incidence of necrosis and ischemia of the nerve during surgical and diagnostic ...

A Rare Anatomical Variation of Sciatic Nerve and its Relationship with Piriformis Muscle

Sciatic nerve is the thickest nerve of the body which is formed by ventral branches of L4, L5, S1, S2 and S3 of spinal nerves as a part of sacral plexus in pelvis. It leaves the pelvis via the greater sciatic foramen below piriformis muscle and descends between the greater trochanter and ischial tuberosity, along the back of the thigh and dividing into the tibial and common peroneal (fibular) n...

Median Nerve Lipofibrohamartoma: A Treatment Dilemma

A Rare Variation of Inferior Laryngeal Nerve: Nonrecurrent Laryngeal Nerve.

A nonrecurrent laryngeal nerve variant of the inferior laryngeal nerve is very rarely seen, and surgeons should keep it in mind during thyroid surgery. Preoperative findings, like situs invertus and dysphagia lusoria, may be suggestive of a nonrecurrent laryngeal nerve. However, these findings always have not to be together with nonrecurrent laryngeal nerve, like our case.

Variation of the median nerve course and its clinical importance.

AIMS AND METHODS In our work we present and describe the variation of the course of the median nerve found in both upper limbs of one of the cadavers in our Institute of Anatomy (Medical Faculty, Comenius University, Bratislava, Slovakia) during the students' dissection of the peripheral nerves and vessels. RESULTS AND CONCLUSION This non-standard course of the median nerve was compared with ...
