TermDefinition
Ampulla Middle portion of the fallopian tube
Cervix Inferior end of the uterus
Corpus albicans Inactive scar tissue that results when the corpus luteum degenerates
Corpus luteum Remnants of the ovarian follicle after ovulation that secretes large amounts of progesterone and small amounts of estrogen
Endometrium Vascular mucous membrane lining the uterus; thickens each cycle in anticipation of receiving a fertilized egg
Epididymis Convoluted tube resting on the side of the testes in which sperm mature
Estrogen Hormone secreted by the ovaries that is responsible for stimulating development of female secondary sex characteristics; it also plays a role in triggering ovulation
Fallopian tubes Tubes extending from near the ovary to the uterus
Gametes Sex cells, which include the speerm in males and the eggs in females
Gonads Primary sex organs; includes the testes in males and the ovaries in females
Graafian follicle A mature follicle of the ovary
Infundibulum Funnel-shaped distal end of the fallopian tube
Isthmus Portion of the fallopian tube closest to the uterus
Meiosis Process of ccell division producing cells (eggs or sperm) that contain half the number of chromosomes found in somatic cells
Menopause The period that marks the permanent cessation of menstruation
Menstruation Cyclical shedding of the uterine endometrium
Myometrium Smooth muscle layer of the uterus; contracts during delivery
Oocyte Immature egg
Oogenesis Process whereby a mature ovum is formed
Ovarian follicle Oocyte and surrounding follicular cells
Perimetrium Outer serous layer of uterine wall
Prostate gland Gland that surrounds the neck of the bladder and urethra in males; secretes alkaline fluid that forms part of semen
Scrotum Sac of tissue surrounding the testes
Semen Whitish fluid containing sperm emitted during ejaculation
Seminiferous tubules Tiny ducts in the testes in which sperm are produced
Spermatogenesis Sperm formation that takes place in the seminiferous tbules of the testicles
Testes Male organs that manufacture sperm and produce the male hormone testosterone
Testosterone Primary male sex hormone secreted by the testes
Uterus Muscular chamber that houses and nurtures a growing embryo and fetus
Vas deferens Tube that carries sperm out of the epididymis to the prostatic urethra
Spermatic cord Strand of connective tissue extending from the abdomen to each testicle
Median septum Divides the scrotum, isolating each testicle
Cremaster muscle Surrounding the spermatic cord, it contracts in cold weather to draw the testes closer to the body for warmth
Rete testis Network of vessels leading away from the seminiferous tubules; provide a location in which sperm partially mature
Efferent ductules Conduct immature sperm away from the testis to the epididymis
Seminal vesicle Located at the base of the bladder; secretes a thick, yellowish fluid into the ejaculatory duct that comprises about 60% of semen
Bulbourethral glands Secretes a clear fluid during sexual arousal; serves as a lubricant and neutralizes the acidity of residual urine in the urethra; Cowper's glands
Glans penis Slightly bulging head of the penis
Prepuce (male) Loose skin covering the penis; foreskin
Gonadotropn-releasing hormone (GnRH) Hormone secreted by the hypothalamus that marks the onset of puberty
Spermatogonia Primitive sex cells with 46 chromosomes located in the walls of the seminiferous tubules
Acrosome Cap topping the head of the sperm containing enzymes that help the sperm penetrate the egg during fertilization
Fimbriae Finger-like projections of the fallopian tube that fan over the ovary
Hymen Fold of mucous membrane that partially covers the entrance to the vagina
Vestibule Area inside the labia containing the urethral and vaginal openings
Prepuce (female) Hood of tissue over the clitoris
Greater vestibular glands On either side of the vaginal opening; secretions help keep the vulva moist and provide lubrication during intercourse; Bartholin's glands
Lesser vestibular glands Open into the vestibule near the urinary meatus, prviding lubrication; Skene's glands
Acini Secrete milk during lactation
Menarche First menstrual period
Contraception Birth control
