Female/Male Reproduction (Chapter 27/28)
Terms in this set (37)
Seminiferous tubuals, sperm production, interstitial cells (testosterone)
Stores,concentrates and transports sperm. Sperm maturation.
Ductus (vas) Deferens
The tube connecting the testes with the urethra. The vas deferens is a coiled duct that conveys sperm from the epididymis to the ejaculatory duct and the urethra. Cut during vasectomy.
Merging of Vas Deferens and Seminal Vesicle
A gland in males that secretes a fluid component of semen that lubricates and nourishes sperm. Produces 60% of seminal fluid.
Sperm activation, a male gland that lies under the urinary bladder and surrounds the urethra
glands located beneath the prostate that secrete a clear, sticky, alkaline fluid that protects sperm by neutralizing the acidic enviroment of the vagina
process by which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell
the first phase of meiosis where homolygous chromsomes are separated, and the cells split in half
The second division of a two-stage process of cell division in sexually reproducing organisms that results in cells with half the number of chromosome sets as the original cell.
produce eggs, estrogen, progesterone. Follicles contain oocytes.
release of oocyte, the expulsion of an ovum from the ovary (usually midway in the menstrual cycle)
endocrine tissue which produces hormones, estrogen, and progesterone which prepares the uterine lining for receiving an embryo (remants)
tubes which carry eggs from the ovaries to the uterus and which provides the place where fertilization occurs
main area of fetal development. Has 3 layers-Endometrium (stratum functionalis), Myometrium, and Serosa
end of uterus
a canal that leads from the uterus to the outside of the body. Birth canal.
external female genitalia; includes the labia, hymen, clitoris, and the vaginal orifice
a mound of fatty tissue covering the pubic area in women
the two outer folds (lips) of the vulva
the two inner folds of the vulva
female erectile tissue between the labia
Paired glands near the posterior side of the vaginal that secrete an alkaline mucus upon sexual arousal. The mucus helps to reduce the acidity of the vagina (which could be harmful to sperm) and lubricates the vagina to facilitate penetration.
two glands in the female breasts that are capable of producing milk
the production, growth, and maturation of an egg, or ovum
Baby girls are born with about 2 million primordial follicles, each containing an oocyte in arrested early meiosis. The vast majority of primordial follicles never develop to the point of ovulation.
immature egg cells in the ovary arrested in prophase of meiosis I at birth.
3 phases: menstral, proliferative, and secretory
Day 1-5, Stratum functionalis sheds
Day 6-14, functionalis is remade, Ovulation occurs on day 14
Day 15-28, Preperation for implantation
Zygote (merged sperm and egg nucleus) - Blastomere - Monula - Blastocytes - Implantation -Cytotrophoblast - Syncytotrophoblasts (forms placenta)
3 germ layers: ectoderm, mesoderm, endoderm (outside in)
The outermost embryonic germ layer that gives rise to the epidermis and the nervous system
The middle germ layer in animal embryos that develops into muscle and bone and cartilage and blood and connective tissue
The innermost germ layer in animal embryos; gives rise to the liver, pancreas, lungs, and the lining of the digestive tract. (Mucosa)
