17
Q

Tunica vaginalis

A

Peritoneal layer of the testis

18
Q

Seminal glands

A

Produce 60-65% of seminal fluid which is high in fructose

19
Q

Spermatic cord

A

Consists of layers of fascia, tough connective tissue, and muscle enclosing the blood vessels, nerves, and lymphatics

20
Q

Dartos muscle

A

Found in the dermis of the scrotum; causes the characteristic wrinkling of the scrotal surface

21
Q

Epididymis

A

Consists of a tubule almost 7 m long, coiled and twisted, lumen is lined by a distinctive pseudostratified ciliated columnar epithelium
It reverses direction

22
Q

Ductus deferens

A

Consists of a tubule 40-45 cm long; it’s wall contains a thick layer of smooth muscle

23
Q

Seminal vesicles

A

Tubular gland around 15 cm long, with a pseudostratified, columnar or cuboidal epithelial lining

24
Q

Ovary

A

Typically a flattened oval that measures approximately 5cm long, 2.5 cm wide and 8mm thick and has a modular consistency

25
Q

Uterine tube

A

A hollow muscular tube measuring roughly 13cm long, whose epithelial lining has both ciliated and nonciliated simple columnar cells

26
Q

Uterus

A

A small pear shaped organ about 7.5 cm long with a maximum diameter of 5cm; its wall consists of an inner glandular mucosa an outer muscular layer and an incomplete aerosol layer

27
Q

Vagina

A

An elastic, muscular tube, highly distensible and variable length and width

28
Q

Infundibulum

A

Expanded funnel-shaped portion of the female reproductive tract; ciliated cells line its lumen

29
Q

What is the blood testis barrier composed of?

A

Tight junctions between extensions of Sertoli cells which function to isolate the luminal portion of the seminiferous tubule from the surrounding interstitial fluids

30
Q

As ovulation approaches the follicular cells surrounding the oocyte are known as?

A

The corona radiata

31
Q

Tunica Albuginea

A

Dense fibrous layer of seminiferous tubules rich in collagen fibers that surrounds the testis
Extends into testis as septa

32
Q

Straight arteries

A

Deliver blood to the basilar layer of the endometrium

33
Q

Follicular phase and corpus luteum

A

Where the ovarian cycle begins at ovulation and ends with the involution.

34
Q

What muscles insert along the sides of the penis and their contractions primarily serve to stiffen the organ

A

Ischiocavernosus muscles

35
Q

Hymen

A

Elastic epithelial fold that separates the vagina and vestibule and which may partially or completely block the entrance to the vagina

36
Q

Gubernaculum testis

A

During development it is a cord of connective tissue and muscle fibers that extends from the inferior part of each testis to the posterior wall of a small, inferior pocket of peritoneum

37
Q

Cardinal ligaments

A

Prevent the inferior movement of the uterus, extends from the base of the uterus and vagina to the lateral walls of the pelvis.

38
Q

Spermatic fascial layers

A

Internal, cremaster muscle and external spermatic facias

Layers of spermatic cord and extends from abdomen

39
Q

Ovarian cycle

A 
Superficial germinal epithelium (cuboidal cells)Primordial follicle
Primary follicle
Developing follicles
Mature (Graafian)
Ruptured follicle (corpus hemorrhagicum)
Ovulation- discharged ovum
Corpus luteum- luteal cells, blood clot, fibrin and mature corpus luteum)
Corpus albicans
40
Q

Dartos

A

Layer of smooth muscle deep to the dermis of the scrotum

41
Q

Inguinal canal

A

Opening in the abdominal wall for spermatic cordial
