SURAL NERVES Meaning and
Definition
-
The sural nerves, in anatomical terms, are peripheral nerves that branch off from the sciatic nerve in the posterior, or back, region of the lower leg. Specifically, they arise near the knee joint and descend along the calf muscle and outer side of the foot. The sural nerves play a crucial role in providing sensory information to certain parts of the lower limb, primarily the skin on the outer side of the foot and the lateral aspect of the lower leg.
These nerves are responsible for transmitting sensory signals, such as touch, temperature, and pain, from the aforementioned areas to the central nervous system. They contain afferent nerve fibers, which carry sensory information from the periphery to the brain and spinal cord for processing and interpretation.
As the sural nerves pass close to the Achilles tendon and other structures in the lower leg, they are susceptible to injury or damage, which can result in symptoms like numbness, tingling, or pain in the outer foot and calf region.
Given their role in sensory perception, the sural nerves are significant in various medical fields. They are crucial in neurological examinations and assessments, as testing the sural nerve response can assist in diagnosing certain nerve disorders or peripheral neuropathies. Additionally, knowledge of the sural nerves is important in surgical procedures, where the surgeon must take precautions to avoid damage to these sensitive nerves.

Etymology of SURAL NERVES
The word "sural" is derived from the Latin word "sura" which means "calf of the leg". The "sural nerves" are a set of nerves that branch off from the sciatic nerve in the popliteal fossa (back of the knee) and innervate the skin of the posterior calf and lateral foot. The term "sural nerves" thus refers to these nerves' location and distribution within the leg, specifically the calf region.
