Bulbospongiosus - Musculus bulbospongiosus


In dogs, the bulbospongiosus muscle (formerly bulbocavernosus muscle) consists mainly of transverse fibers covering the superficial surface of the bulb of the penis.

Origin: tunica albuginea lateral to the spongious body of penis, which is compressed by the muscle

Insertion: median septum



In female domestic mammals, because of the elongated vestibule, the bulbospongiosus is divided into constrictor vestibuli and constrictor vulvae.
