Reproductive System: Exam 6 pt.1

Female reproductive organ housing the embryo.

Uterus

Hormone-releasing structure post-ovulation.

Corpus Luteum

Release of a mature egg from the ovary.

Ovulation

Union of sperm and egg, typically in fallopian tube.

Fertilization

Fertilized egg attaches to uterine lining.

Implantation

Shedding of uterine lining through vagina.

Menstruation

End of menstrual cycles, occurs around age 50.

Menopause

Immature egg surrounded by granulosa cells and theca cells.

Follicle

Cells providing nutrients to developing oocyte.

Granulosa Cells

Cells surrounding follicles, producing androgens.

Theca Cells

Spike in LH triggering ovulation around day 14.

LH Surge

Hormone stimulating follicle growth in ovaries.

FSH

Hormone promoting endometrial repair and follicle growth.

Estrogen

Hormone stabilizing uterine lining during luteal phase.

Progesterone

Phase that happens in the uterus where endometrial lining is maintained(stratum functionale).

Secretory Phase

Phase that happens in the ovaries post-ovulation, creates corpus luteum that secretes hormones.

Luteal Phase

Hormone maintaining corpus luteum during pregnancy(3-6 months).

hCG

What maintains progesterone and estrogen levels high during pregnancy after corpus luteum dies at 6 months?

Placenta

Site for sperm maturation in males.

Epididymis

Testicular cells producing testosterone.

Leydig Cells

Support and nourish developing sperm.

Sertoli Cells

Primary male sex hormone, regulates spermatogenesis.

Testosterone

Converts testosterone into estrogen.

Aromatase

Site of sperm production in testes.

Seminiferous Tubules

Tube transporting sperm from epididymis.

Ductus Deferens

Gland contributing to seminal fluid production.

Prostate Gland

Pouch regulating temperature of testes.

Scrotum

Finger-like projections aiding egg transport to uterus.

Fimbriae

immature eggs found inside follicles

oocyte

Layer of the myometrium that lines the uterine wall

Stratum Basale

Cells found lining the uterus that grow when stimulated by estrogen and progesterone.(this layer is shed during the menstrual phase)

Stratum Functionale

During what day of the cycle do all women ovulate?

Day 14

Survival period for an ovum that does not get fertilized or implanted to the lining?

48-72 hours

FSH affects which cells in the Follicle and what do they do?

Granulosa cells and they stimulate the follicles growth

LH affects which cells in the follicle and what do they do?

Theca cells and they cause the ruption of the follicle
