Flashcards in Chapter 17 Terms Male Deck (30):
1

A membranous sac on the head of a sperm cell that contains enzymes that facilitate sperm penetration in to the egg during fertilization.

Acrosome

2

Synthetic hormones that mimic testosterone and stimulate the body to build muscle and increase strength. Abusing this can have many dangerous side effects.

Anabolic Steroids

3

x

Anterior Pituitary

4

Male accessory reproductive glands that release a clear slippery liquid immediately before ejaculation.

Bulbourethral Glands

5

x

Ejaculation

6

A gland that lacks ducts and releases its products (hormones) into the fluid just outside the cell.

Endocrine Glands

7

x

Epididymis

8

x

Erectile Tissue

9

x

Erection

10

x

FSH

11

Reproductive cells (sperm and egg) that contains only one copy of each chromosome. A sperm and egg fuse at fertilization, producing a zygote.

Gametes

12

An ovary in a female or a testis in a male. The gonads produce gametes (sperm and egg) and sex hormones.

Gonads

13

x

Hernia

14

Chemical messengers released by cells of the endocrine system that travels through the circulatory system to affect receptive target cells.

Hormones

15

A passage through the abdominal wall through which the testes pass in their descent to the scrotum.

Inguinal Canal

16

Cells located between the seminiferous tubules in the testes that produce the steroid sex hormones, collectively called androgens.

Interstitial cells

17

A hormone secreted by the anterior pituitary gland that in females stimulates ovulation and the formation of the corpus luteum (which produces estrogen and progesterone)and prepares the mammary glands for milk.

LH (luteinizing hormone)

18

An accessory reproductive gland in males that surround the urethra as it passes from the bladder. Its secretions contribute to semen and serve to activate the sperm and to counteract the acidity of the female reproductive tract.

Prostate Gland

19

A loose fleshy sac containing the testes.

Scrotum

20

x

Secondary sex characteristics

21

The fluid expelled from the penis during a male orgasm. Consists of sperm and the secretions of the accessory glands.

Semen

22

A pair of male accessory reproductive glands located posterior to the urinary bladder. Their secretions contribute to semen and serve to nourish the sperm cells, reduce acidity in the vagina, and coagulate sperm.

Seminal Vesicles

23

x

Seminiferous Tubules

24

The series of events within the seminiferous tubules that gives rise to physically mature sperm from germ cells. It involves meiosis and maturation.

Spermatogenesis

25

The male gonads. The male reproductive organs that produce sperm and the hormone testosterone.

Testes

26

A sex hormone needed for sperm production and the maintenance of male reproductive structures. Produced primarily by the interstitial cells of the testes.

Testosterone

27

A hormone that influences another endocrine gland.

Tropic Hormones

28

x

Undescended Testicles

29

The muscular tube that transports urine from the floor of the urinary bladder to the outside of the body. In males, it also conducts sperm from the vas deferens out of the body through the penis.

Urethra

30

A tubule that conducts sperm from the epididymis to the urethra.

Vas Deferens
