The perineal body (or central tendon of perineum) is a pyramidal fibromuscular mass in the middle line of the perineum at the junction between the urogenital triangle and the anal triangle. In males, it is found between the bulb of the penis and the anus ; in females, it is found between the vagina and anus, and about 1.25 cm (0.49 in) in front ...
Perineal may refer to: The perineum , the region of the body between the pubic arch and the tail bone Perineal artery , an artery supplying the perineal region
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]
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 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 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 interval between the posterior commissure and the anus, from 2.5 to 3 cm in length, constitutes the perineum. [8] The anterior region of the perineum is known as the urogenital triangle, which separates it from the anal region. Between the labia majora and the inner thighs are the labiocrural folds. Between the labia majora and labia minora ...
The perineal nerve is a branch of the pudendal nerve. [1] [2] It lies below the internal pudendal artery.It accompanies the perineal artery.It passes through the pudendal canal for around 2 or 3 cm. [1] [2] Whilst still in the canal, it divides into superficial branches and a deep branch. [1]
