Sural Nerve

The Sural Nerve (/ˈsʊrəl ˈnɜːrv/), is a sensory nerve in the human body that originates from the Tibial Nerve and the Common Peroneal Nerve, both branches of the Sciatic Nerve.

Etymology

The term "sural" is derived from the Latin word "sura" meaning calf, which is the area of the leg where the nerve is located.

Function

The Sural Nerve provides sensory innervation to the skin of the lateral foot and lower lateral surface of the leg. It is often used as a graft or for biopsies due to its non-essential role in motor function.

Anatomy

The Sural Nerve is formed by the union of two cutaneous branches of the lower leg: the medial sural cutaneous nerve (branch of the Tibial Nerve) and the lateral sural cutaneous nerve (branch of the Common Peroneal Nerve). It runs down the center of the calf to the lateral side of the foot.

Related Terms

  • Nerve Graft: A surgical method of repairing a damaged nerve by using a segment of a healthy nerve from another part of the body, often the Sural Nerve.
  • Nerve Biopsy: A diagnostic procedure where a small sample of a nerve, often the Sural Nerve, is removed and examined under a microscope.
  • Peripheral Neuropathy: A condition resulting from damage to the peripheral nerves, which can include the Sural Nerve.
