The superficial perineal pouch is an open compartment, due to the fact that anteriorly, the space communicates freely with the potential space lying between the superficial fascia of the anterior abdominal wall and the anterior abdominal muscles:
The fascia of perineum (deep perineal fascia, superficial investing fascia of perineum or Gallaudet fascia) is the fascia which covers the muscles of the superficial perineal pouch. The muscles surrounded by the deep perineal fascia are the bulbospongiosus , ischiocavernosus , and superficial transverse perineal .
Colles' fascia emerges from the perineal membrane, which divides the base of the penis from the prostate. Colles' fascia emerges from the inferior side of the perineal membrane and continues along the ventral (inferior) penis without covering the scrotum. It separates the skin and subcutaneous fat from the superficial perineal pouch.
The subcutaneous tissue of perineum (or superficial perineal fascia) is a layer of subcutaneous tissue surrounding the region of the perineal body. The superficial fascia of this region consists of two layers, superficial and deep. The superficial layer is thick, loose, areolar in texture, and contains in its meshes much adipose tissue, the ...
The following areas are thus classified as parts of the perineal region: perineal pouches: superficial and deep (see above for details) ischioanal fossa – a fat-filled space at the lateral sides of anal canal, bounded laterally by the obturator internus muscle, and medially by the pelvic diaphragm and anal canal; its base is the skin anal canal
The perineal membrane is an anatomical term for a fibrous membrane in the perineum. The term "inferior fascia of urogenital diaphragm", used in older texts, is considered equivalent to the perineal membrane. It is the superior border of the superficial perineal pouch, and the inferior border of the deep perineal pouch.
The deep perineal pouch is bordered inferiorly by the perineal membrane, also known as the inferior fascia of the urogenital diaphragm. It is bordered superiorly by the superior fascia of the urogenital diaphragm. [1] The deep pouch is now described as the region between the perineal membrane and the pelvic diaphragm. [2]
However, while Bartholin's glands are located in the superficial perineal pouch in females, bulbourethral glands are located in the deep perineal pouch in males. Their duct length is 1.5 to 2.0 cm and they open into navicular fossa. [2] The ducts are paired and they open on the surface of the vulva. [3]
