What is the function of the bulbocavernosus muscle?
Bulbocavernosus Muscle Function It aids in the emptying of the greater vestibular glands in females by constricting the vaginal orifice. The anterior fibres compress the deep dorsal vein of the clitoris, facilitating clitoris erection.
Where is bulbocavernosus muscle located?
bulbocavernosus muscle, also called Bulbospongiosus, a muscle of the perineum, the area between the anus and the genitals. In the male, it surrounds the bulb (the enlarged inner end of the structure that surrounds the urethra) of the penis and can be contracted to expel the last drops of urine or semen.
What is a bulbocavernosus reflex test?
The test involves monitoring internal/external anal sphincter contraction in response to squeezing the glans penis or clitoris, or tugging on an indwelling Foley catheter. This reflex can also be tested electrophysiologically, by stimulating the penis or vulva and recording from the anal sphincter.
How do you test Bulbocavernosus?
Procedure. The test involves monitoring internal/external anal sphincter contraction in response to squeezing the glans penis or clitoris, or tugging on an indwelling Foley catheter. This reflex can also be tested electrophysiologically, by stimulating the penis or vulva and recording from the anal sphincter.
Who discovered bulbocavernosus reflex?
Bulbocavernosus reflex (BCR) Bors and Blinn first described the BCR in 1959 , which is also known as clitoroanal , penilo-cavernosus , and Osinski reflex .
What is bulbospongiosus muscle?
Bulbospongiosus muscle. The bulbospongiosus is a muscle found in the superficial perineal pouch which covers the bulb of the penis in males and the bulb of the vestibule in females.
Is bulbospongiosus dimorphic?
Bulbospongiosus muscle (Musculus bulbospongiosus) Bulbospongiosus is a paired muscle of the pelvic floor. It is found in the superficial perineal space (pouch), together with the ischiocavernosus and superficial transverse perineal muscles. Bulbospongiosus is a sexually dimorphic muscle, meaning that it is different among sexes.
What is the blood supply to the bulbospongiosus?
Blood supply to bulbospongiosus comes from the internal pudendal artery, via its branch; the perineal artery. In males, the function of bulbospongiosus is to aid in emptying the penile urethra during urination and ejaculation.
How are the attachments of bulbospongiosus different among males and females?
The attachments of bulbospongiosus are different among males and females. In males, the muscle consists of two parts that are fused at the median fibrous raphe of penis. In addition, the fibers originate from several surrounding structures; perineal body, superficial transverse perineal muscle and external anal sphincter.
