|
||||
| Luteal Phase | Phase of ovarian cycle that occurs after ovulation; estrogen levels decline; previous LH surge also transforms the ruptured follicle into the corpus luteum and causes it to begin to secrete hormones.
🗑
|
||||
| Menstruation | Shedding of endometrium caused by falling progesterone levels.
🗑
|
||||
| Myometrium | Layer of the uterus which contains smooth muscle cells
🗑
|
||||
| Nitric Oxide | Produced in response to parasympathetic reflex; causes arterioles of the penis to dilate in an erection
🗑
|
||||
| Ovary | Primary sex organ in the female.
🗑
|
||||
| Ovulation | When estrogen levels get really high, the anterior pituitary is stimulated to release a burst of LH around day 14 and this occurs.
🗑
|
||||
| Perimetrium | Outermost layer of uterus; also part of the visceral peritoneum
🗑
|
||||
| Primary follicle | A developing oocyte with multiple surrounding granulosa cells
🗑
|
||||
| Primordial follicle | A developing oocyte with a single layer of surrounding cells
🗑
|
||||
| Prostaglandins | Component of semen; decreases viscosity of cervical mucus; stimulates reverse peristalsis of the uterus
🗑
|
||||
| Prostate gland | Produces an acidic fluid which contains citrate (nutrient) and several enzymes which activate the sperm
🗑
|
||||
| Scrotum | Contains testes
🗑
|
||||
| Seminal Vesicles | Produce an alkaline fluid containing fructose, coagulating enzymes, ascorbic acid, and prostaglandins
🗑
|
||||
| Seminiferous tubules | Sperm are produced here
🗑
|
||||
| Testes | Primary sex organ in the male.
🗑
|
||||
| Testosterone | Stimulates the male secondary sex characteristics; causes sperm formation; responsible for sex drive in both sexes
🗑
|
||||
| Uterine tube | Most common place for fertilization to take place.
🗑
|
||||
| Uterus | Functions to receive, retain, and nourish a fertilized ovum
🗑
|
||||
| Vesicular Follicle | The oocyte bulges from the surface of the ovary just prior to ovulation
🗑
|
||||
| Zygote | Fertilized egg; first cell of the new individual
🗑
|
||||
| Three components of Ejaculation | 1. Reproductive ducts and accessory glands contract and empty contents into the urethra,
2. Bladder sphincter muscle constricts preventing urine expulsion or reflux of semen, and 3. Smooth muscles of penis contract
🗑
|
||||
| Secretion of FSH and LH | These stimulate follicle growth and maturation and estrogen secretion. As estrogen rises it shuts down the release of FSH and LH from the pituitary but FSH and LH are still being produced and stored.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
