Wild felids often suffer spinal and limb disorders; however, their nervous system anatomy is poorly studied. Herein, the lumbosacral plexus ( Plexus lumbosacralis ) of an adult puma and the motor and sensitive innervation of the pelvic limb is described. We found anatomical similarities to other felids, but also some differences. Branches L4‐S3 form the lumbosacral plexus ( Plexus lumbosacralis ) in the puma. The femoral nerve ( N. femoris ) arises from the union of L4‐L5, while in other felids, it is formed by L5‐L6. Unlike in the cat, the sartorius muscle receives branches from the saphenous ( N. saphenous ) and femoral nerves ( N. femoris ), and the lateral head of the gastrocnemius and superficial digital flexor muscles are innervated by a branch of the soleus muscle.
