What is a sphincter structures?
a ring of muscle that controls the release of an organs products. EXAMPLE: Pyloric Sphincter controls release of chyme. Cardiac Sphincter controls deposition of food into the stomach from the esophagus. External Urethral Sphincter controls release of urine. External Anal Sphincter controls release of defecation.

Dorsal muscle of the head and trunk?
Dorsal muscles of the head and trunk include the serratus posterior, the serratus posterior superior, the splenius capitis, the spinalis, the latissimus dorsi, the multifidus, and the sphincter ani internus. They also include the transversus perinea profundus, the urethral sphincter, the external urethral sphincter, and the urethrovaginal muscles.
Which nerve supplies the pelvic floor?
The pudendal nerve (part of the somatic nervous system, voluntary control) innervates the pelvic floor. It also innervates the external urethral sphincter; the internal urethral sphincter is innervated by the pelvic nerve (part of the parasympathetic nervous system, involuntary control).
