Card Set Information
Holes Human Anatomy and Physiology
What are the primary organs of the male reproductive
accessory sex organs(internal and external reproductive organs)
Where are the sperm cells formed?
cell division that halves the genetic material, resulting in egg and sperm cells
How many chromosomes are in a sperm cell?
Name the structures of the sperm cell.
flattened head, cylindrical midpiece and an elongated tail
What is contained in the acrosome?
hyaluronidase, aid the sperm cell in penetrating
produce sperm cells
produce and secrete male sex hormones
promotes sperm cell maturation, stores sperm cells, conveys sperm cells to ductus deferens
conveys sperm cells to ejaculatory duct
secretes an alkaline fluid that helps neutralize the acidic components of semen and enhances sperm cell motillity
secretes an alkaline fluid containing nutrients and prostanglandins that helps neutralize the acidic components of semen
secretes fluid that lubricates end of the penis
encloses, protects, and regulates temperature of testes
conveys urine and semen to outside of body; richly supplied with sensory nerve endings associated with feelings of pleasure
What hormones are involved in the male reproductive
What hormone is the most abundant androgen?
Testosterone-secreting cell in the interstitial area, between the seminiferous tubules, in the testis.
stimulates the development of the male reproductive organs and causes the testes to decend; resposible for the development and maintenance of male seconday sex charateristics
What temperature is approximately maintained in the
testes for sperm?
What happens if the testes do not descend?
they will not produce sperm cells because of the temperature, the male is infertile
differentiation of an egg cell; beginning at puberty
when a primary oocyte divides, the cytoplasm is distributed unequally; the resulting larger cell is called _______?
when a primary oocyte divides, the cytoplasm is distributed unequally; the resulting smaller cell is called _______?
first polar body
What happens to polar bodies during fertilization?
they begin to degenerate 15 hours post fertilization
the primary oocyte enlarges, the follicular cell proliferate, and a fluid fulled cavity appears and produces a secondary follicle
What causes ovulation?
release of LH from the anterior pituitary gland
produces oocytes and female sex hormores
conveys secondary oocyte toward uterus; site of fertilization; conveys developing embryo to uterus
protects and sustains embryo during pregnancy
conveys uterine secretions to outside of body; provides open channel for offspring during child birth
enclose and protect other external reproductive organs
form margina of vestibule; protect openings of vagina and urethra
produces feelings of pleasure during sexual stimulation due to abundant sensory nerve endings in glans
space between lania minora that contains vaginal and urethral openings
secrete fluid that moistens and lubricates the vestibule
the infundibulum bears a number of irregular, branched extensions called _________?
inner mucosal layer, is covered with columnar epithelium and contains abundant tubular glands
thick, middle, muscular layer, consists largely of bundles of smooth muscle fibers in longitudinal, circular and spiral patterns and is interlaced with connective tissues
consists of an outer serosal layer, which covers the body of the uterus and part of the cervix
neck of the uterus; tubular part extends downward into the upper part of the vagina
responsible for the development and maintenance of most female secondary sex characteristics
prepares the uterus for pregnancy
What are the major events in a menstrual cycle?
regularly recurrin changes in the uterine lining culminating in menstrual flow
structure that forms from the rupturedovarian follicle and secretes female hormones
cessation of the female reproductive system
composed of 15 to 20 irregualry shaped lobes. each lobe contains glands, drained by alveolar ducts
hormone secreted by the anterior pituitary gland that stimulates the production of milk in the mammary glands
Where is milk stored in the mammary gland?
the milk is stored in the alveolies and small milk ducts
withdrawal of the penis from the vagina before ejaculation; some semen may be expelled from the penis before ejaculation
abstinence from sexual intercorse two days before andone day after ovulation
males and females can use condoms; females use diaphragms and cervical caps
spermicical film, sponges, suppositories, foams and gels
flexible ring inserted into the vagina, a plastic patch, or pill can deliver estrogen and progestin to prevent pregnancy
combined hormone contraceptives
intramuscular injection with medroxyprogesterone acetate every three months prevents pregnancy
solid object inserted into the uterine cavity
vasectomy is performed in males
tubal ligation is performed in females
Which substances are contained in oral contraceptives?
estrogen and progestin
human immunodeficiency virus
acquired immune deficiency syndrome AIDS
chlamydia trachomatis bacteria
herpes simplex 2 virus
human papilloma virus
neisseria gonorrhoeae bacteria
treponema pallidum bacteria
