Study Notes
Pelvic Floor Muscles
- The Iliococcygeus muscle helps to support pelvic organs.
Muscles of the Pelvic Floor
- The Bulbospongiosus muscle originates from the perineal body in males.
- The Bulbospongiosus muscle originates from the clitoris in females.
Ischiocavernosus Muscle Function
- In females, the Ischiocavernosus muscle helps to compress the clitoris and pump blood into the erectile tissue.
Fecal Continence
- The Iliococcygeus muscle assists in fecal continence.
Superficial Transverse Perineal Muscle
- The Superficial Transverse Perineal Muscle inserts into the perineal body.
- The Superficial Transverse Perineal Muscle originates from the ischiopubic ramus.
- The Superficial Transverse Perineal Muscle helps to compress the urethra and assist in urinary continence.
Ischiocavernosus Muscle
- In males, the Ischiocavernosus muscle helps to compress the crus of the penis and pump blood into the erectile tissue.
- The Ischiocavernosus muscle inserts into the crus of the penis in males.
Innervation
- The Superficial Pelvic Floor Muscles are innervated by the pudendal nerve (S2-S4).
- The Coccygeus (Ischiococcygeus) muscle is innervated by the pudendal nerve (S2-S4) and the coccygeal nerve (S4-S5).
Coccygeus Muscle
- The Coccygeus (Ischiococcygeus) muscle inserts into the coccyx and sacrum.
