| Question | Answer |
|---|---|
| Another name for reproductive cells is | gametes |
| The male organs of reproduction are the | testes |
| The two products of the testes are sperm and | hormones |
| Suspended below the perineum is a fleshy pouch containing the testes called the | scrotum |
| The failure of the testes to descend into the scrotum is called | cryptorchidism |
| The nerves, ducts, and blood vessels emerging from the testes together form the | spermatic cord |
| The canal through which the spermatic cord passes into the peritoneal cavity is the | inguinal canal |
| The interstitial cells of the testes are responsible for producing | sex hormones |
| The process through which sperm are produced is | sprematogenesis |
| During the process of meiosis a spermatocyte with 46 chromosomes will produce a spermatid having chromosomes that number | twenty-threee |
| The chromosomes of the sperm are packed into the region of the cell known as the | head |
| The site of sperm maturation over a period of about two weeks is a duct called the | epididymis |
| Another name for the ductus deferens is the | vas deferens |
| The tubular extension of the epididymis extending through the inguinal canal is the | ductus deferens |
| Within the abdominal cavity, the ductus deferens passes over the top and posterior surface of the | urinary bladder |
| At the ampulla, the ductus deferens joins with the duct leading from the | seminal vesicle |
| The duct passing from the urinary bladder to the tip of the penis is the | urethra |
| Older males may experience interference with urination if there is enlargement of the | prostate gland |
| The two small glands secreting mucus and alkaline substances and situated at the base of the penis are called | bulbourehtral glands |
| The root, shaft, and glans are three portions of the | penis |
| Most of the body of the penis consists of tissue that is | erectile |
| Erection of the penis takes place after the accumulation of | blood |
| The opening of the penis to the exterior is the | external urethral meatus |
| The male hormone that promotes sperm maturation and maintains the accessory organs is called | testosterone |
| The general name for male hormones that accelerate puberty and initiate sexual maturation is | androgens |
| The organs where oocytes are produced in the female reproductive tract are the | ovaries |
| Hormones produced by cells of the female reproductive tract are progesterone and | estrogen |
| The expanded funnel of the uterine tube is the | infundibulum |
| The projections that extend from the uterine tube into the pelvic cavity are | fimbriae |
| Fertilization of the oocyte by the sperm usually takes place in the | uterine tube |
| Transport of the oocyte through the uterine tube is encouraged by the movement of hairlike cell appendages of epithelial cells called | cilia |
| The hollow organ where the embryo develops in the female is the | uterus |
| The uterine tubes enter the uterus at the bulging upper surface of the body of the uterus called the | fundus |
| The neck of the uterus that projects into the vagina is called the | cervix |
| The inner tissue layer of the uterine wall partially sloughed off during menstruation is the | endometrium |
| The middle layer of the uterine wall composed of thick muscle layers is the | myometrium |
| The muscular tube extending between the uterus and the external genitalia is the | vagina |
| The fold of epithelium partially blocking the entrance to the vagina prior to sexual activity is the | hymen |
| The muscular tube where sperm cells are deposited during sexual intercourse is the | vagina |
| The vulva is an alternate term for the | external genitalia |
| The small mass of erectile tissue that enlarges during female sexual arousal is the | clitoris |
| During sexual intercourse, lubricants are produced by the glands known as the greater vestibular gland and the | paraurethral gland |
| Two elongated folds of skin that encircle and partially conceal the labia minora and structures of the vestibule are the | labia minora |
| After birth, the newborn gains nourishment from milk secreted from the | mammary glands |
| The production of milk is called | lactation |
| The pattern of physiological and structural changes in the female reproductive tract occurring in response to changes of ovarian hormones is known as the | menstrual cycle |
| The length of time for a complete menstrual cycle to occur is about | 28 days |
| A surge of estrogen and progesterone accompany the release of the oocyte from the follicle, a process known as | ovulation |
| The number of chromosomes present in the mature oocyte is | 23 |
| When an oocyte unites with a sperm, the resulting fertilized oocyte is called the | zygote |
| Within the uterus, the organ producing hormones and providing a medium for the transfer of nutrients, gases, and waste products between embryonic and maternal bloodstreams is the | placenta |
| During the first two months after implantation, the developing individual is referred to as a | embryo |
| The germ layer that develops in to the skeletal muscles, cardiac muscles, blood, bone, and other organs is the | mesoderm |
| The heartbeat begins, ossification takes place in bones, and the body systems are developing during pregnancy in month number | three |
