Muscle associated with pelvic
urethra and the penis • Urethralis muscle: striated muscle, suround pelvid
urethra in circular manner, thick, powerfull muscle responsible for movement of semianl plasma and spermatozoa into penile urethra
• Bulbospongiosus muscle: overlap the root of the penis and extends down the caudal and ventral surfaces, also covers bulbourethral glands, to empty the extrapelvic part of the urethra
• Ischiocavernosus muscle: paired, associated with pelvic urethra and the penis, connect the penis to ischial arch
