Final answer:
The innervation of the levator ani muscle is provided by the pudendal nerve.
Step-by-step explanation:
The innervation of the levator ani muscle is provided by the pudendal nerve. The levator ani is an important muscle of the pelvic floor that supports the pelvic viscera and creates skeletal muscle sphincters at the urethra and anus. The pudendal nerve arises from the sacral micturition center and is responsible for controlling urination and maintaining continence during filling of the bladder.
