1

The ______ divides the pelvic cavity into a false and true pelvis.

Pelvic brim

NOTE: The boundaries of the pelvic brim are the pubic symphysis (anteriorly) and the sacral promotory (posteriorly). 

Additional note: The pelvic brim is more round in females than in males.

2

Primary sex organs

  • Testes and ovary
    • Produce the sex cell or gametes
    • Secrete sex hormones

3

Accessory sex organs

  • Glands
  • Ducts
  • The external genitalia

6

Ductus deferens gets wider behind the bladder called the ___________.

Ampulla of ductus deferens

7

The external positioning keeps the testes _________ degrees celcius lower than core body temperature. 

3

NOTE: This is reuired for sperm production

8

The _____________is the pouch of serous membrane that covers the testes.

tunica vaginalis 

NOTE: It is derived from the vaginal process of the peritoneum, which in the fetus precedes the descent of the testes from the abdomen into the scrotum. Facilitates testicular movement

10

What two muscles keep intrascrotal temp steady?

Dartos

  • Smooth muscle that wrinkles scrotal skin

Cremaster

  • Bands of skeletal muscle that elevate the testes

NOTE: Both muscles are innervated by the genitofemoral nerve

11

Function of testes

12

What are the two layers of the tunica vaginalis?

  • Lamina parietalis
  • Lamina vaginalis

*Below the lamina vaginalis is the tunica albuginea

13

14

How long does sperm stay in the head of the epididymis?

20 days

*During this time, the sperm matures. It then travels to the tail and then to the vas deferens.

15

In the adult, the testis is surrounded by a serous membrane, the production of too much serous fluid results in a _________.

Simple hydrocele

NOTE: Normally, the process vaginalis is pushed through the anterior abdominal wall. The layers are obliterated and liquid cannot go up and down.

16

Criptorchidism

Undescended testis

NOTE: The testes develop in the upper abdominal posterior wall and descend into the developing scrotum, as a result of the gubernaculum getting shorter and shorter. 

17

Testes and ovaries descend to the scrotum and pelvic cavity, respectively, through the _________.

18

Where does the round ligament of the uterus terminate?

Labia majora

*Synonymous with scrotum

19

What are the contents of the spermatic cord?

  • Vas deferens
  • Testicular artery
  • Pampiniform plexus of veins
  • Genitofemoral nerve
  • Cremaster muscle

20

Varicocele

Varicose veins in the scrotum

*A varicocele is made up of veins that contain inadequate valves.

21

What is the course of the vas deferens?

  • Scrotum
  • Tranverses inguinal canal
  • Enters pelvis
  • Terminates posterior to the bladder and medial to the seminal vesicle

22

The ejaculatory duct is formed by the union of the ducts of the _____________ and ___________.

Vas deferens; seminal vesicle

23

What are the contents of the seminal vesicle?

  • 60% of the volume of semen that contains fructose and other nutrients that nourish the sperm
  • Fluid with yellow pigment that fluoresces under UV light

24

The ____________ secretes a milky white fluid that mekes up 40% of semen.

Prostate

NOTE: Prostatis is the most common reason for males to visit the urologist

25

In the adult, only the ________ (female/male) urethra persists as a duct common to both the urinary and reproductive systems. 

Male

26

Label

27

The ejaculatory duct runs in the prostate to end in the _________.

Prostatic urethra

28

Which structures are supplied by the inferior vesical artery?

  • Lower part of the urinary bladder
  • Prostate/vagina

NOTE: The inferior vesical artery may arise from the middle rectal artery or the inferior vesical artery will anastomose with the middle rectal artery. 

29

Function of the bulbourethral glands

  • Produce a mucus which neutralizes traces of acidic urine in urethra and lubricates the urethra to smooth the passage of semen during ejaculation. 

30

Bulbourethal glands are located in the ___________.

Urogenital diaphragm
