Q

Male Pelvic Region: describe

  • immature sperm will enter _____, upon stimulation it will enter _______

bulbourethral glands emit ______ upon stimulation

A

Testis are outside the body, immature sperm will enter the epididymis–> upon stimulation it will enter vas deferens–> and ampulla of the ductus deferens merges with the seminal vesicles and the ejaculatory duct in the prostate– ejaculatory duct merges with the urethra in the prostate–> as the urethra leaves the prostate–> enters urogenital diaphragm= membranous urethra.

Bulbourethral glands– emit an alkaline mucous into the spongy urethra upon stimulation and this allows for control of pH and bacteria so the sperm successfully leave the body

Q

Development of sperm in the seminiferous tube:

summary

A

Spermatogonium is located right on the outside of the smooth muscle layer on the outside of the seminiferous tubule. The smooth m will contract and enhance the movement of cells as they differentiate-– down towards the seminiferous tube
Spermatogonium–> goes through mitosis (creates 2 separate primary spermatocytes which have 46 pairs of chromosomes–> surrounded by susentacular cells (=Sertoli cells) they tightly fuse on the developing spermatocyte to create a tight junction–> Meiosis 1 (split down to secondary spermatocyte (with 23 pairs)–> also increase cytosol of spermatocyte–> Go through meiosis 2 and produce 4 spermatids (23 singles)–> these spermatids are pushed through the tight junction into the lumen–> this process= spermatogenesis!

Pay attention to= blood testis barrier–> not exactly a structural formation its more created by susentacular cells (aka Sertoli cell barrier) which helps to est. different chemical environments
–it blocks lymphocytes, it blocks complement, it can be problematic cuz lymphocytes may attack spermatids AND WE DON’T WANT THIS. We need to produce sperm

(my summary: Testisincluding the seminiferous tubules–> rate testis epididymis ductus deferens–> ampulla of seminal vesicle seminal vesicle comes together w ejaculatory duct to deliver seminal fluid ampulla at the seminal vesicle deposits sperm coming up through ductus deferens you are now in the ejaculatory duct at the beginning of the prostate now inside the prostate gland where prostatic fluid is deposited int the prostatic urethra now in the urogenital diaphragm–> membranous urethra  bulbourethral gland deposits bulbourethral secretion into the urethra–> spongy urethra goes for bulb of penis into outside world )

Q

Hormonal Regulation Spermatogenesis/Androgen Production:

-starting with the Hypothalamus releasing GnRH, describe the steps that lead to production of testosterone

A
  1. GnRH released from hypothalamus–> stimulates anterior pituitary
  2. Anterior pituitary releases FSH and LH
  3. FSH stimulates sustentacular cells in the seminiferous tubule (for sperm production)
  4. Sustentacular cells produce ABP
  5. ABP is stimulatory for
    Testosterone (and this stimulates MORE spermatogenesis)
  6. While LH will stimulate interstitial cells (interstitial cells are MAIN testosterone producers)–> stimulates testosterone production
  7. Testosterone levels will be the main negative feedback, with testosterone negatively feeding back on the Hypothalamus AND the anterior pituitary. Hypothal will reduce GnRH production and Ant pituitary will decrease FSH and LH
  8. Sustentacular cells also produce inhibin–> Inhibin will also inhibit anterior pituitary from releasing FSH and LH
69
Q

_____ stimulates the interstitial cells of the testes to secrete____

  2. Stimulation of Genital region, especially glans
  3. Internal pudendal nerve–> spinal cord (sacral area) –> pelvic nerve (= efferent parasympathetic signals)
  4. -Deep artery of penis dilates; erectile tissues engorge w blood; penis becomes erect.

    - And the Bulbourethral gland secretes bulbourethral fluid
72
Q

describe

A
  1. Ejaculation:
    – Spinal Cord (L1-L2)–> **Efferent sympathetic signals-> leads to emission stage (=orgasm)
    -ductus deferens exhibits peristalsis; sperm are moved into ampulla; ampulla contracts; sperm are moved into urethra
    -prostate secretes components of the seminal fluid
    -seminal vesicles secrete components of the seminal fluid —>
    LEADS to: semen in urethra-> Expulsion stage (orgasm): –> Afferent signals–> Spinal cord (L1-L4):
  • First phase: Efferent sympathetic signals–>
  • Prostate releases additional secretion
  • seminal vesicles release additional secretion
  • internal urethral sphincter contracts; urine is retained in the bladder

-2nd phase: Efferent somatic signals: Bulbocavernosus muscle contracts, & rthymically compresses bulb and root of penis; semen is EXPELLED (=ejaculation occurs)

73
Q

Third Phase: Resolution/Refractory (list steps)

A

Spinal cord (L1/L2)–> sends efferent sympathetic signals–> Resolution:

  • Internal pudendal artery constricts; reduces blood flow into penis
  • Trabecular muscles contract; squeeze blood from erectile tissues
  • Penis becomes flaccid (detumescent)

127
Q

Hormonal Interactions in the Ovarian Cycle:

-Describe the steps in the follicular phase and Late follicular, ovulation, and Luteal Phase

A

Most of Follicular phase:
1. Hypothalamus secretes GnRH, which stimulates anterior pituitary.
2. At Ant. Pituitary: FSH and LH stimulate follicular development
3. Maturing ovarian follicles secrete inhibin (which inhibits FSH production) and low levels of estrogen (which initially inhibit both the hypothalamus and anterior pituitary).
4. Estrogen also assists w the development of the mature follicle (LOW estrogen levels at this time)
Late Follicular, ovulation and Luteal phase
5. Mature follicle produces a large threshold amount of estrogen, which stimulates thehypothalamus and anterior pituitary.
Estrogen is at HIGH levels now
6. An LH surge from the anterior pituitary induces ovulation.
7. LH The corpus luteum forms under the influence of LH
8. LH surge induces ovulation*** The corpus luteum secretes large amounts of progesterone, estrogen, and inhibin, which inhibit the hypothalamus and anterior pituitary.
9. Negative Feedback: Progesterone, estrogen and inhibin negatively feedback on ant pituitary and hypothalamus

128
