Ch 23 Reproductive

The male and female reproductive sys

What is the process of cell division that halves the chromosome number in a cell to produce a gamete? meiosis
What is the male gamete called? spermatozoon or sperm cell
What is the male gonad? testis
What is the structure on the surface of the testis that stores sperm? epididymis
What glands, aside the testis, contribute secretions to semen? the seminal vesicles, prostate, and bulbourethral glands.
What glands are the main subdivisions of a spermatozoon? the head, midpiece, and tail, (flagellum)
What two pituitary hormones regulate both male and female reproduction? LH and FSH
Which cell type in the testis produces the main male sex hormone? leydig cells
What is the term for failure of the testis to descend? cryptorchidism
What does the abbreviation STI mean? sexually transmitted infection
What is the female gamete called? ovum
What is the female gonad called? ovary
In what organ does a fetus develop? uterus
In what structure does an ovum mature? ovarian follicle
What are the two hormones produced in the ovaries? estrogen and progesterone
What process releases an ovum from the ovary? ovulation
What does the follicle become after its ovum is released? the follicle becomes a corpus luteum
What is the term describing the complete cessation of menstrual cycles? menopause
What term describes the use of artificial means to prevent fertilization of an ovum? contraception
What is amenorrhea? absence of menstrual flow.
What is the common term for a myoma, a benign uterine tumor? fibroid
What is oligospermia? low sperm count.
Corpus luteum yellow body formed from ovarian follicle after ovulation.
Endometrium lining of the uterus.
Estrogen group of female sex hormones that promotes development of the uterine lining and maintains secondary sex characteristics.
Follicle-stimulating hormone (FSH) hormone produced by the anterior pituitary that stimulates development of ova in the ovary and spermatozoa in the testes.
Gamete reproductive cell/ ovum or spermatozoon.
Infertility decreased ability to reproduce.
Luteinizing hormone (LH) hormone produced by the anterior pituitary that induces ovulation and formation of the corpus luteum in females; in males it stimulates cells in the testes to produce testosterone.
Menopause time during which menstruation ceases.
Menses monthly flow of blood from the female reproductive tract.
Menstruation the period of menstrual flow.
Ovarian follicle a fluid filled sac that contains a immature egg or oocyte
Ovary female gonad/reproductive gland
Ovulation release of a mature ovum from a follicle in the ovary.
Ovum female gamete/ reproductive cell or gamete
Progesterone hormone produced by the corpus luteum and placenta; maintains the lining of the uterus for pregnancy.
Semen mixture of sperm cells and secretions from several glands of the male reproductive tract.
Spermatozoon male gamete/ reproductive cell
Testis male gonad/ reproductive gland
Testosterone male sex hormone produced in the testes; promotes the development of sperm cells and maintains secondary sex characteristics
Uterus muscular pear shaped organ in the female pelvis within which the fetus develops during pregnancy.
Gametes go through a special process of cell division called meiosis
Spermatozoa begin their development in tiny coiled seminiferous tubules
An ovum matures in a small fluid-filled cluster of cells called the follicle
Failure of the testis to descend into the scrotum results in the disorder cryptorchidism
Surgical removal of the uterus is called a hysterectomy
A hormone released by the pituitary that promotes follicular development in the ovary follicle-stimulating hormone (FSH)
A hormone released by developing follicles that promotes thickening of the endometrium estrogen
A hormone released by the pituitary that stimulates ovulation luteinizing hormone (LH)
A hormone released by the corpus luteum that peaks after ovulation progesterone
The main male sex hormone testosterone
What structure does the fetal testis travel through to descend into the scrotum? inguinal canal
Where are the enzymes that help the sperm cell penetrate the ovum located? acrosome
What is testicular inflammation called? orchitis
What structure suspend the uterus and ovaries in the pelvic cavity? broad ligaments
What is the term for the area between the vaginal opening and the anus? perineum
Where is the most common site of cancer in the female reproductive tract? endometrium
PID Pelvic inflammatory disease
STI Sexually transmitted infection
HPV Human papillomavirus
LH Luteinizing hormone
BPH Benign prostatic hyperplasia
