25
Q

the seminal vesicle…..

A

  • only their lateral, uppermost portion is covered by parietal peritoneum
26
Q

where do the secretory ducts of the seminal vesicle open

A

30
Q

blood supply of the prostate

32
Q

what is the penis composed of?

A

- corpus spongiosum (surrounds the urethra)

33
Q

penis is divided in to?

A

root and body

34
Q

origin of the root of the penis?

A

inferior pubic rammi, by the r. and l. cura of the penis

35
Q

what is the cura of the penis and what is it surrounded by?

A

the extensions of the corpus cavernosum, surrounded by the ischiocavernosus muscle

36
Q

what is the bulb of the penis?

A

thickened end of the corpus spongiosum, between the two cura’s and is covered by the bulbospongiosus muscle

37
Q

what is the fundiform ligament of the penis?

A
  • band of elastic tissue of the subcutaneous tissue that extends from the linea alba to the pubic symphisis,
  • surrounds the penis before attaching to the fascia of the penis
38
Q

what is the suspensory ligament?

A

a ligament connecting the anterior surface of the pubic spymphisis and the junction between the root and body of the penis

39
Q

what is the penis covered with?

A

thin skin with no fat and covered by:

  • subcutaneous tissue of the penis
  • prepuce of the penis/foreskin (folds of skin no fat covers the glans penis)
