Cutaneous innervation of the lower limbs
(Redirected from Cutaneous innervation of the lower limb)
Cutaneous Innervation of the Lower Limbs refers to the supply of nerves to the skin of the lower limbs. This innervation is responsible for the sensation of touch, temperature, pain, and other stimuli in the skin of the lower limbs. The nerves that provide cutaneous innervation to the lower limbs originate from the lumbar plexus and the sacral plexus, which are networks of nerves in the lower part of the spine.
Anatomy[edit | edit source]
The cutaneous innervation of the lower limbs is divided into several areas, each supplied by different nerves:
- The anterior and medial aspects of the thigh are innervated by the Anterior cutaneous branches of the femoral nerve.
- The lateral aspect of the thigh is innervated by the Lateral cutaneous nerve of thigh.
- The posterior aspect of the thigh and the upper part of the back of the leg are innervated by the Posterior cutaneous nerve of thigh.
- The front of the leg and the dorsum of the foot are innervated by the Superficial fibular nerve.
- The lateral aspect of the leg and the little toe are innervated by the Sural nerve.
- The sole of the foot is innervated by the Medial plantar nerve and the Lateral plantar nerve.
Clinical Significance[edit | edit source]
Damage to the nerves supplying the skin of the lower limbs can result in a loss of sensation, known as Peripheral neuropathy. This can be caused by a variety of conditions, including diabetes, Vitamin B12 deficiency, and Leprosy. In addition, certain surgical procedures, such as hip replacements or knee replacements, can potentially damage these nerves and lead to changes in sensation.
