Anatomical terms of muscle |
The bulbospongiosus muscles (in older texts bulbocavernosus and, for female muscle, constrictor cunni) are a subgroup of the superficial muscles of the perineum.[1] They have a slightly different origin, insertion and function in males and females. In males, these muscles cover the bulb of the penis, while in females, they cover the vestibular bulbs.
In both sexes, they are innervated by the deep or muscular branch of the perineal nerve, which is a branch of the pudendal nerve.
