Branches of Sacral Plexus 3D

  • Sciatic Nerve
    • * Formed from the anterior rami of L4 to S3 spinal nerves.
    • * Courses through the posterior thigh and divides into the tibial and common fibular (peroneal) nerves.
    • * Innervates the posterior thigh and lower leg muscles.                                                                                                                                                             
  • Pudendal Nerve
    • * Arises from sacral spinal nerves S2 to S4.
    • * Exits the pelvis through the greater sciatic foramen, then re-enters through the lesser sciatic foramen.
    • * Provides sensory and motor innervation to the perineum, external genitalia, and anal sphincters.

 

  • Superior Gluteal Nerve
    • * Arises from L4 to S1 spinal nerves.
    • * Exits the pelvis through the greater sciatic foramen.
    • * Innervates the gluteus medius, gluteus minimus, and tensor fasciae latae muscles.

 

  • Inferior Gluteal Nerve
    • * Arises from L5 to S2 spinal nerves.
    • * Exits the pelvis through the greater sciatic foramen.
    • * Innervates the gluteus maximus muscle.

 

  • Nerve to Piriformis​​​​​​​
    • * Arises from spinal nerves S1 and S2.
    • * Innervates the piriformis muscle.

 

  • Posterior Cutaneous Nerve of the Thigh​​​​​​​
    • * Arises from spinal nerves S1 to S3.
    • * Provides sensory innervation to the posterior thigh and leg.

 

  • Nerve to Quadratus Femoris and Gemellus Inferior​​​​​​​
    • * Arises from spinal nerves L4 to S1.
    • * Innervates the quadratus femoris and gemellus inferior muscles.

 

  • Nerve to Obturator Internus and Gemellus Superior​​​​​​​
    • * Arises from spinal nerves L5 to S2.
    • * Innervates the obturator internus and gemellus superior muscles.

 

  • Nerve to Levator Ani and Coccygeus​​​​​​​
    • * Arises from spinal nerves S3 and S4.
    • * Innervates the levator ani and coccygeus muscles.
