- Latin synonym: Nervus cutaneus surae lateralis
- Synonym: Lateral cutaneous nerve of calf
Definition
The lateral sural cutaneous nerve (n. cutaneus suræ lateralis; lateral cutaneous branch) supplies the skin on the posterior and lateral surfaces of the leg; one branch, the Sural communicating branch (peroneal anastomotic; n. communicans fibularis), arises near the head of the fibula, crosses the lateral head of the Gastrocnemius to the middle of the leg, and joins with the medial sural cutaneous to form the sural nerve. The peroneal anastomotic is occasionally continued down as a separate branch as far as the heel.
