Reproductive System Flashcards
Starting at the site of sperm production, and ending out of the urethra label the sections of the “tube” that the sperm travels through
Testes Epididymis Duct Ductus Deferens Ejaculatory Duct Urethra
State the function of the seminal vesicle, bulbourethral glands, and prostate glands
- Seminal Vesicle: help regulate PH of the tubular contents s sperm travels to the outside, neutralizes the acidic secretion of the vagina
- Bulbourethral Gland: Secretes mucus like fluid in response to sexual stimulation, fluids lubricates the end of the penis in preparation for sexual intercourse
- Prostate Gland: secrets milky fluid, contains citriate, nutrient for sperm PSA enzyme helps liquify semen
Starting at the sperm stem cell name the cells at the different stages of sperm development
Spermatogonium Primary Spermatocyte Secondary Spermatocyte Early Spermatids Late Spermatids Sperm
Which cells have 46 chromosomes (Diploid) and which have 23 chromosomes (Haploid)
Multicelluar Diploid 2n=46 (Spermatogonium)
Haploid gamete n=23 (secondary Spermatocyte)
What are the roles of LH and FSH in the male reproductive system
LH: promotes development of interstitial cells of the testes and in turn they secrete male sex hormones
FSH: Stimulate spermatogenic cells to undergo spermatogenesis giving rise to sperm cells
Where is testosterone made and what is its major role in males
Adrenal Cortex
Stimulates enlargement of the testes and accessory organs or reproductive system as well as secondary male characteristics
What are the gonads and gametes of the male and female reproductive tract
Gonads: Testes, Ovaries
Gametes: Sperm, Ova
Starting with the stem cell, name the cells at the different stages of ova development, which ones are diploid and which ones are haploid
Oogonium Primary oocyte= diploid Secondary oocyte= haploid First Polar body=haploid Polar bodies=haploid Zygote=diploid
Name the major function of Estrogen and Progesterone in the female
Estrogen- stimulates enlargement of accessory organs, help develop female secondary characteristics
Progesterone- Promotes changes in the Uterus during the female reproductive cycle, affects mammary glands
Help regulate the secretion of the gonadotropins
Describe the development of the follicle in the ovary, include the names of the different stages of follicle development
Primary Follicle-contains immature oocyte
Growing follicle-growing follicle with a maturing oocyte
Ovulation-when the egg is mature and follicle raptures
Raptures Follicle- the rapture follicle is transformed into corpus luteum
What are the roles of LH and FSH in the Follicle Development process
LH: triggers ovulation
FSH: Stimulates development of maturing ovarian follicle, controls ovum production
Zygote
First cell of new individual
Results of fusion of DNA from sperm and egg
Begins rapid mitotic cell division
Zyoptic stage is in the utrerine tube moving towards uterus
Morula
16-cell stage
Solid Ball
Hollows out to form blastocyte
Blastocyte
Ball like circle of cells
Begins at about 100 cell stage
Secretes human chorionic gonadotropinto induce the rcopus luteum to continue producing hormones
Late Blastocytes implants in the wall of the uterus by day 14
Embroy
First undergoes division without growth
Enters the uterus at the 16-cell stage about 3 days afet ovulation
Floats freely in the uterus temporarily
Uterine secretions are used for nourishment
