- t/f Testosterone is secreted in a fetus until birth, and then not again until puberty, after which it is continuously secreted.
- t/f The medulla of the ovaries is made up of connective tissue, blood vessels, lymphatic vessels, and nerves. The outer context contains follies and is covered by cuboidal epithelium.
- In males the ___________ releases gonadotropin-releasing hormone (GnRH) which triggers the production of the gonadotropins luteinizing hormone (LH), and follicle-stimulation hormone (FSH) from the _______ ____________.
- t/f Sperm cells cannot fertilize an egg until they undergo capacitation within the female reproductive tract.
- The ______ is a pouch of skin ad subcutaneous tissue that houses the testes suspended from the lower abdomen, posterior to the penis.
- In the male embryo, the spermatogenic cells are undifferentiated and are called _________ that each contain 46 chromosomes.
- The ______ _______ are small structures located inferior to the prostrate that secrete _______ to lubricate the tip of the penis during sexual arousal.
- The _______ is a cylindrical organ made up of specialized erectile tissue( corpora cavernosa and corpus spongiosum - enlarges at the distal end to form the glans penis) and is designed to convey both urine and semen to the outside.
- The _____ _______ is a muscular tube 45 centimeters in length leading from the epididymis up into the body cavity to the ejaculatory duct, where it unites and empties its contents into the urethra..
- The _______ ______ is a chestnut-shaped structure surrounding the urethra at the base of the urinary bladder. It secretes a thin, milky _____ ____ that both enhance the mobility of sperm cells and neutralizes the acidity of the by-products produced during spermatogenesis and the acidity of the female reproductive tract.
- The _______ ________ is a saclike structure attached to the vas deferens near the base of the urinary bladder.
- During emission, seminal vesicles secrete an alkaline fluid containing _______ to nourish sperm and prostaglandins to cause muscular contractions int he female tract to help propel sperm to the egg cell.
- ______________ is the production of sperm cells in which the spermatogonia enlarge and become primary spermatocytes that undergo meiosis to form haploid secondary spermatocytes with 23 chromosomes.
- _______ is the combination of sperms cells and the secretions of the seminal vesicles, prostrate gland, and bulbourethral glands.
- Each _________ is a tightly coiled tube lying adjacent to the testis and leading from the testis to the vas deferent. They are the site of sperm maturation.
- t/f Secondary spermatocytes divide again after meiosis to form spermatids, each of which mature into a sperm cell to finish the process of spermatogenesis.
- How long does it take for a sperm to mature?
- ____________ organs of the reproductive system make sex cells whereas __________ organs transport the egg or sperm cells to the site of fertilization.
- t/f A cystitis is a bladder infection which is more common in females due to a short length of the urethra.
- Parts of a sperm cell:________: front piece containing the haploid nucleus ________: middle that contains mitochondria ________: flagellum piece
