The deep branch of the perineal nerve (or muscular branches) is a nerve of the perineum. It is a branch of the perineal nerve, from the pudendal nerve. It supplies the superficial transverse perineal muscle, bulbospongiosus muscle, ischiocavernosus muscle, the bulb of penis, levator ani, and the external anal sphincter.
The deep perineal pouch contains: muscles Deep transverse perineal muscles; External sphincter muscle of male urethra; External sphincter muscle of female urethra; Compressor urethrae muscle in the female is sometimes included [3] Urethrovaginal sphincter in the female is sometimes included [3] other
The deep transverse perineal muscle is innervated by the pudendal nerve. The function of the muscle is fixation of the perineal body (central tendon of perineum), support of the pelvic floor, expulsion of semen in males and last drops of urine in both sexes. [2] The deep transverse perineal muscle lies in the same plane as the urethral ...
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 ...
Female pelvic muscles Male pelvic muscles. The pelvic floor or pelvic diaphragm is an anatomical location in the human body, [1] which has an important role in urinary and anal continence, sexual function and support of the pelvic organs. [2] The pelvic floor includes muscles, both skeletal and smooth, ligaments and fascia.
The perineal membrane has two distinct portions that span the opening of the anterior pelvic outlet. [2]The ventral (anterior) portion is associated with the compressor urethra and urethrovaginal sphincter muscles (previously called deep transverse perineal muscles), and is continuous with the insertion of the arcus tendineus fascia pelvis. [3]
When either of these muscles contracts, the urethra is sealed shut. The external urethral sphincter originates at the ischiopubic ramus and inserts into the intermeshing muscle fibers from the other side. It is controlled by the deep perineal branch of the pudendal nerve. Activity in the nerve fibers constricts the urethra.
