By Dr. Joseph H Volker | 2018-08-30T10:54:59+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

Plantar Nerves are the nerves that go through the ankle joint to the sole of the foot. Plantar refers to anything that is related to the sole of the foot. There are 2 plantar nerves- medial and lateral. Medial Plantar Nerve The medial plantar nerve is the pre-axial nerve of the foot. Origin And Course [...]

Nerves of Foot

By Dr. Joseph H Volker | 2018-08-30T09:56:21+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

Main innervation of foot is done by the: Tibial Nerve Deep Fibular Nerve Superficial fibular Nerve Sural Nerve Saphenous Nerves Tibial Nerve The tibial nerve travels inside the foot via the tarsal tunnel, posterior towards the medial malleolus. The nerve lies lateral towards the posterior tibial artery inside the tunnel and also produces medial calcaneal [...]

Femoral Nerve

By Dr. Joseph H Volker | 2018-08-30T08:45:51+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

Femoral Nerve is the main nerve of anterior compartment of thigh. It originates from the dorsal sections of the anterior primary rami of L2, L3, L4 nerves and is the largest branch of lumbar plexus. It goes into the thigh behind the inguinal ligament and lateral to femoral sheath while descending via psoas major and [...]

Cutaneous Innervation of The Lower Limb

By Dr. Joseph H Volker | 2018-08-30T08:48:24+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

The branches of nerves of sacral and lumbar plexuses are the points of origin of cutaneous nerves that supply the lower limb , the exception being some proximal unisegmental nerves that originate from T12 or L1 spinal nerves. The lateral and posterior cutaneous nerves of thigh and cutaneous branches of the femoral nerve are responsible [...]

Segmental Innervation of The Lower Limb

By Dr. Joseph H Volker | 2018-08-30T08:50:23+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

Segmental Innervation of The Skin (Dermatomes) Dermatome is area of the skin that has supply by a single spinal nerve. The point of development of lower limb bud is on the venterolateral part of body wall that is opposite of L1-S3 sections of spine, afterwards these sections of spinal cord distribute nerves in skin of [...]

Obturator Nerve

By Dr. Joseph H Volker | 2018-08-30T09:06:20+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

Obturator Nerve belongs to the adductor compartment of the thigh. The inside of psoas major from anterior sections of the ventral rami of L2 to L4 spinal nerves. The nerve goes down in psoas major and issues from its medial border at the ala of the sacrum. It runs through the upper anterior part of [...]

Sympathetic Innervation of The Lower Limb

By Dr. Joseph H Volker | 2018-08-30T08:51:15+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

The (T10 to L2) i.e lower three Thoracic and upper two Lumbar sections of spinal cord act as the originating point of sympathetic distribution of nerves in lower limb. The point of origin of preganglionic fibres is from lateral horn cells through the ventral roots. After that they pass downwards in the sympathetic chain while [...]

Sciatic Nerve

By Dr. Joseph H Volker | 2018-08-30T09:32:33+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

Sciatic Nerve is the thickest nerve in the body. At the beginning it is 1.5 to 2 cm wide. It is composed of 2 parts tibial and common peroneal nerves and its point of origin is in pelvis of ventral rami of L4 to S3 spinal nerves. Ventral sections of anterior primary rami [...]

Cutaneous Nerves of the Front of the Thigh

By Dr. Joseph H Volker | 2018-08-30T11:14:00+00:00 August 8th, 2018|Anatomy, Lower Limb, Nerves|0 Comments

The skin of the front of the thigh is supplied by seven cutaneous nerves derived directly, or indirectly, from the lumbar plexus. In addition, the skin over the upper lateral part of the thigh is supplied by the lateral cutaneous branch of the subcostal nerve. The ilioinguinal nerve (L1) emerges at the superficial inguinal ring, [...]
