Q

What is the function of seminal fluid

A

Components that induce capacitation of sperm cells (the induction of physical changes that allows the sperm cells to penetrate and fertilize the egg), while also acting as an immunosuppressive on the female genital tract

important for semen coagulation and sperm motility

Q

Two functions of the pelvic diaphragm

A
  • Support of abdominopelvic viscera through their tonic contraction.
  • Urinary and faecal continence. The muscle fibres have a sphincter action on the rectum and urethra. They relax to allow urination and defecation.

Q

What is contained within the superficial peritoneal pouch?

A

Erectile tissues that form the penis and clitoris
and three muscles – the ischiocavernosus, bulbospongiosus and superficial transverse perineal muscles.

Bartholin’s glands are also located in the superficial perineal pouch. The pouch is bounded posteriorly to the perineal body.

Q

WHat is contained withinthe deep perineal pouch?

A

> Part of the urethra, external urethral sphincter, and the vagina in the female. In males, it also contains the bulbourethral glands and the deep transverse perineal muscles.

Q

WHat is the posterior border of hte perineal membrane attached to?

A

The perineal body

18
Q

What is the function of the external anal sphincter

A

Voluntary control of defication

19
Q

What is the function of hte superficial trasnverse perineal muscle?

A

Flexes and stabalises the perineal body

20
Q

What is the function of the deep transverse perineal muscle?

A

Forms the urogenital diaphragm and anchors the perineal body, supporting the pelvic viscera

21
Q

What is the function of the bulbospongiosus muscle in males?

A

WHen contracted stops the flow of urine

aids in fully emptying the urethra after urination.

contracts rhythmically during ejaculation, fascilitating movement of ejaculate through the urethra

22
Q

What is the function of the ischiocavernosus muscle in males?

A

Steady contraction aiding in maintenance of erection.

  • The muscle also undergoes rhythmic contraction in conjunction with bulbospongiosus during ejaculation.
  • help maintain the erection and possibly to aid in moving the ejaculate through the urethra.
23
Q

What is the function of the ischiocavernosus muscle in females?

A

Compress the corpus cavernosus muscle, restricting venous return and allowing clitoral errection in females

24
Q

What is a secondary function of the urethral sphincters?

A

Prevent retrograde ejaculation of semen into the bladder

25
Q

Function of bartholins glands

A

secrete lubricating mucus from small ducts during sexual arousal. They are located either side of the vaginal orifice.

26
Q

What fascia covers the deep transverse perineal muscle

A

Perineal membrane

27
Q

Innervation of the internal urethral sphincter

A

Autonomic, sympathetic
T10-L2 (prevents you from needing the loo)
