18. What is cremaster? What happens to the penis when it contracts?
Definition
creamster is when sexual arrousal on temperature change occurs, it contracts to pull the testes toward the body (to maintain the temperature of the sperm)

Dense connective layer that projects inside the testes to form septate.

20. What is spermiogenesis?
Definition
  • Speratid matures and becomes a spermatozoon (sperm)
  • Spermatocytes and spermatids are surround by cytoplasm of sustentacular cell
  • takes 9 weeks from spermatocyte to complete spermiation.

22. if a person starts taking injection testoterone daily for 3-4 weeks, what changes of his:

  1. Sex Drive
  2. GnRH
  3. FSH

Do you expect???

Definition
Term
23. Where is sperm production located?
Definition
Term
24.  Put in the correct order the structures of the male reproductive tract?
Definition
Term
25. Functions of epididymis.
Definition

1. it monitors and adjusts the composition of the fluid produced by the seminiferous tubules.

2. it acts as a recycling center for damaged spermatozoa.

3. it stores and protects spermatozoa and facilitates their functional maturation.

Term
26. function of the prostate gland.
Definition

= produce prostatic fluid- a slightly acidic solution that contributes 20-30% of the volume of semen.

Term
27. Role of parasympathetic nerves in the vessels of the penis and the testes.
Definition
Term
28. What do the secretions of the prostate gland include?
Definition

-seminalplasmin = an antibiotic that may help prevent urinary tract infections in males.

Term

29. What does semen contain?

Definition

- the fluid ejaculate that contains spermatozoa and the secretions of accessory glands of the male reproduction tract.

Term
30. What do preputial glands secrete?
Definition
= secrete a waxy material known as smegma.
Term
31. What is the difference between corpus spongiosum and corpus cavernosum?
Definition

corpus spongiosum (1corpura spongium) = sorrounds the penile urethra, extend from the superficial fascia of the urogenital diaphram to the tip of the penis, contains more elastic fiber and contains a pair of small arteries.

corpus cavernosum ( 2 copura cavernosa) =

separated by a thin septum and encircled by a dense collagenous sheath, sorround a central artery.

Term
32. functions of testosterone?
Definition

1. stimulating spermatogenesis

2. increases libido

3. promote anabolism

4. maintains 2nd sexual characteristics

5. 70% bound to GBG

6. 30% bound to GBA

7. 1st production at 7th wk, max at 6th month to suppress Mullerian ducts

Term
33. What pituitary hormone controls testosterone?
Definition

LH

Term
34.) What is the broad ligament?
Definition
An extensive mesentery that encloses the ovaries, uterine tubes and uterus.
Term
35.) What is the uterine tube?
Definition
(aka Fallopian tube/oviduct) a hollow muscular tube measuring roughly 13 cm (5.2inches) in length. 3 segments: Infundibulum Ampulla Isthmus
Term
36.) What is the infundibulum?
Definition
Segment of the uterine tube. The end closest to the ovary forms an expanded funnel. The inner serfcaes are lined with Cilia that beat toward the middle segment of the uterine tube called the ampula.
Term
37.) Ovulation : What hormone triggers ovulation?
Definition
LH - Leutinizing Hormone
Term
38.) What happens during the secretory and proliferative phases of the menstrual cycle?
Definition
SECRETORY: - Progesterone and estrogen from corpus luteum stimulate gland enlargement and increase secretion.
Term
39.) What are menses?
Definition
- Degeneration of functional zone by constriction of spiral arteries. - Blood pours to connective tissues and enters to the uterine cavity and vagina. - Basilar zone supplied by straight arteries that remains unconstricted - The degeneration occurs gradually last 2-7 days (35-50cc blood lost)
Term
39.) What are menses?
Definition
- Degeneration of functional zone by constriction of spiral arteries. - Blood pours to connective tissues and enters to the uterine cavity and vagina. - Basilar zone supplied by straight arteries that remains unconstricted - The degeneration occurs gradually last 2-7 days (35-50cc blood lost)
Term
40.) What causes menses?
Definition
- Degeneration of functional zone by constriction of spiral arteries.
Term
41.) Functions of the vagina?
Definition
- Passageway for mense discharge - Receiving penis and hold sperm - Birth Canal for delivery
Term
42.) Factors needed for both erection and ejaculation occur?
Definition
ERECTION: When the smooth muscles in the arterial walls relax when NO (nitric oxcide) is released, at which time the vessels dialate, blood flow increases, the vascular channels become engorged with blood. EJACULATION: - Occurs as powerful, rhythmic contractions appear in the ischiocavernosus and bulbospongiosus muscles, two superficial skeletal muscles of the pelvic floor.
Term
43.) What is the difference between emmission and ejaculation?
Definition

ejaculation = the ejection of semen from the penis as the result of muscular contractions of the bulbospongiosus and ischiocavernosus muscles.

emission = occurs under symphatetic stimulation.the process begins when the peristaltic contractions of the ampulla push fluid and spermatozoa into the prostatic urethra.

Term
44.) What hormone does the corpus luteum secrete?
Definition
oestrogens and progesterone, which are steroid hormones (responsible for the thickening of the endometrium and its development and maintenance, respectively.)
Term
45.) Symptoms of menopause
Definition
- Number of follicles decrease, sso estrogen decreases, ovulation stops (at 50 YO, no follicles left) - The decrease of estrogen lead to the reduction of size of breast and uterus - osteosporosis, hot flashes, anxiety, depression due to LH
Term
46.) Causes of amenorrhea.
Definition
Primary - deformity of uterus, non-functional ovaries, hormonal disorders Sencondary - pregnancy, illness, stress, starvation (lack of lipid)
Term
47.) What is capacitation?
Definition
process the spermatozoa needs to go through to become motile. 2 Steps: 1.) When spermatazoa are mixed with secretions of the seminal vesicles. 2.) they become capable of successful fertilization when exposed to conditions in the female reproductive tract.
Term
48.) What is polyspermy?
Definition
fertilization by more than one sperm.
Term
49.) What is Amphimixis?
Definition
When the male and female pronuclei fuse (step 4 in fertilization). The cell is now a zygote that contains the normal complement of 46 chromosomes and fertilization is complete. (Moment of conception)
Term
50.) What is smegma?
Definition
a waxy material produced by the preputial glands (located in the skin of the neck, the inner surface of the prepuce).
Term
51.) What is the "Broad ligament" of the uterus?
Definition
the wide fold of peritoneum that connects the sides of the uterus to the walls and floor of the pelvis.
