The system that ensure the continued exsistence of the human species is: Reproductive Functional male and female reproductive cells are called: Gametes The reproductive organs that produce reproductive cells and hormones are the: Gonads Reproductive cells are recieved and transported by a system of: Ducts Perineal structures are collectively known as: External Genitalia In adult males, the testes secrete sex hormones called: Androgens The male gonads produce males gametes called: Spermatoza Sperm, mixed with secretions of accesorry glands, create a mixture known as: Semen The female gonads are called the: Ovaries Once a month the female gonads release an immature oocyte, that, if fertilized by a sperm matures to become what? An ovum The structures within the testes responsible for sperm production are the: Seminiferous Tubules The correct sequence of travel for sperm through the males reproduction tract is: Epididymis, Vans Deferens, Ejaculatory Duct Seminal fluid exits the penis through the: Urethra A bundle of tissue that contains the vans deferens, blood, vessels, nerves, and lymphatics and serves the testes is the: Spermatic Cord Androgens are produced in: Interstitial Cells Sperm storage and maturation occurs in the: Epididymis Sperm production occurs in the: Seminiferous Tubules The 3 processes involved in spermatogenesis are: Mitosis, Meiosis, and Spermiogenesis Sperm develop from "primordial cells" called: Spermatogonia When the process of meiosis begins, developing sperm cells become: Spermatocytes At the end of meiosis, the immature sperm are called: Spermatids The process of spermiogenesis produces: Spermatozoa Once sperm cells leave the testes, the route they take on their way out of the body of the male is through the epididymis, _____________, ejaculatory duct, ___________: Vans deferens, Urethra The accessory organs in the male that secrete into the ejaculatory ducts and the urethra are the: Seminal esicles, Prostate Gland, and Bulbourethral Glands Sperm move from the epididymis to the urethra via the: Vans Deferens Seminalplasmin in the prostatic fluid is an: Antibiotic That May Help Prevent Urinary Tract Infections in Males The gland that contributes about 60% to the volume of semen and produces slightly alkaline secretion that contains fructose is the: Seminal Vesicles The gland that surrounds the urethra at the base of the urniary bladder and produces an alkaline secretion is the: Prostate Gland The small paired glands at the base of the penis that produce a lubrication sectrion are the: Bulbourethral Glands What is the male organ or copulation? Penis What is the fold of skin that covers the tip of the penis? Prepuce The erectile tissue that surrounds the urethra is the: Corpus Spongiosum The erectile tissue located on the ventral surface of the penis is the: Corpus Cavernosa The hormone that is synthesized in the hypothalmus and initiates the release of pituitary hormones is: GnRH The hormone that promotes spermatogenesis along the seminiferoud tubules is: FSH Testosterone plays a secondary role in the sperm production because: At Low Concentrations it Stimulates the Release of FSH The hormone responsible for seconadry sex charcteristics in the male is: Testosterone The pituitary hormone that stimulates the interstitial cells to secrete testosterone is: LH The production of female gametes and the secretion of female sex hormones is the function of the: Ovaries A developing embryo recieves mechanical protection and nutritional support in the: Uterus The mass of erectile tissue located at the anterior margin of the labia minora is the: Clitoris The muscular layer of the uterus is the: Myometrium The inferior portion of the uterus that projects into the vagina is the: Cervix In the mammary gland, milk production occurs in the: Lobules The central space bounded by the labia minora is the: Vestibule Fleshy folds that encircle and partially conceal the labia minora and vestibular structures are the: Labia Majora The generally dark, pigmented skin that surrounds the mammary nipple is called the: Areola The process of oogenesis produces three nonfunctional polar bodies and a: Functional Ovum Ova develop from stem cells called: Oogonia The start of meiosis in the female begins between: The third and seventh months of fetal development The second meiotic division in the female is not completed until: After Fertilization The number of ova produced by the process of oogenesis is: 1 The hormonal signal to complete meiosis occurs when the female: Reaches Puberty The proper sequence that describes the ovarian cycle involved the formation of primary follicles, secondary follicales, tertiary follicles, ovulation and: primary follicles, secondary follicles,tertiary follicles, ovulation, and formation and destruction of the corpus luteum Under normal circumstances, in a 28-day cycle, ovulation occurs on day ____, and menses begins on day___. 14; 1 During the proliferative phase of the menstual cycle: A New Functional Layer is Formed in the Uterus During the secretory phase of the menstrual cycle: Glands Enlarge and Their Rate of Secretion is Accelerated During menses: The Old Functional Layer is Sloughed Off At puberty in the male and the female levels of FSH and LH increase, secondary sex characteristics begin to appear as well as: Gametogenesis Begins The hormone that initiates oogenesis is: FSH The hormone that initiates ovulation is: LH The principal hormone secreted by the corpus luteum is: Progesterone The hormone that causes a thickening of the endometrium to prepare the body for pregnancy is: Progesterone During pregnancy, the levels of estrogen and progesterone remain quite high to inhibit the release of : FSH What cells make progesterone? Leydig Cells What is another word for sex? Coitus What is estrogen that dominates follicular phase of ovarian cycle? Estradiol What phase repairs growth of enometrium? Proliferative Phase What is the very first period called? Menarche
