The Cutaneous Innervation of the Lower Limb.
11 wrz 2023 · Muscles: anterior, medial and posterior groups. Arteries: femoral artery and its branches. Veins: femoral vein, circumflex vein, long saphenous vein, and deep vein of the thigh. Nerves: femoral and sciatic nerves, branches from the lumbar and sacral plexuses, respectively. Knee. Bones: tibia, fibula, patella.
6 dni temu · The nerves of the leg and foot arise from spinal nerves connected to the spinal cord in the lower back and pelvis. As these nerves descend toward the thighs, they form two networks of crossed nerves known as the lumbar plexus and sacral plexus.
10 paź 2023 · Now it’s time to look at the nerves of the lower limb, which stem from the lumbosacral plexus. The significant ones of the hip and thigh are the following: femoral, saphenous, femoral cutaneous (lateral and posterior), sciatic, obturator, gluteal (superior and inferior), and cluneal (superior, medial, and inferior) nerves.
30 paź 2023 · The lower cervical and first thoracic anterior rami form the brachial plexus (supplies upper limb). The lower lumbar and upper sacral anterior rami form the lumbosacral plexus (supplies lower limb). The thoracic anterior rami remain segmental becoming the intercostal nerves in the intercostal spaces.
Sacral plexus; Lumbosacral plexus. ventral rami of S1-4; joined with lower lumbar nerves via lumbosacral trunk Sciatic N (L4-S3) Superior gluteal N (L4-S1): gluteus med and min (greater trochanter; abduction of hip joint) Inferior gluteal N (L5-S2): gluteus max (gluteal tuberosity; extension, lateral rotation of hip joint) Pudendal N (S2-4 ...
