THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The muscular components sphincter urethrae and deep transverse perinei with perineal membrane together are known as the urogenital diaphragm.

Detailed explanation-2: -The bulbospongiosus muscle (striated muscle) adheres anterolaterally to the PB. Deep transverse perineal muscle (male) adheres laterally to the PB. Compressor urethra muscle (female) adheres anteriorly to the PB. The external anal sphincter muscle adheres posterolaterally to the PB.

Detailed explanation-3: -The deep transverse perenei are muscles of the pelvic diaphragm running transversely across the pelvic floor. They are continuous with the sphincter urethrae muscle anteriorly. They originate from the medial surface of the ischiopubic ramus. They insert into a midline raphe and the perineal body.

Detailed explanation-4: -FEMALE: The Transversus perinaei profundus arises from the inferior rami of the ischium and runs across to the side of the vagina. The Sphincter urethrae membranaceae (Constrictor urethrae), like the corresponding muscle on the male, consists of external and internal fibers.

Detailed explanation-5: -Muscles. Deep transverse perineal muscles. External sphincter muscle of male urethra. External sphincter muscle of female urethra. Other. Membranous urethra in the male; proximal portion of urethra in the female. Bulbourethral gland (male).
