TEAS REPRODUCTION

Bulbourethral gland

Gland just inferior to the prostate gland that secretes mucous in response to sexual stimulation.

corpus luteum

• promotes and maintains implantation of t

  

  he embryo

Epididymis

• A highly convoluted duct located behind the testis

• sperm matured are transported to the vas deferens.

• Sperm move through the in about 10-15 days

penis

The male genital organ carrying the duct for the transfer of sperm during copulation; consists largely of erectile tissue and serves also for the elimination of urine

scrotum

The sac that holds testes away from the body to maintain lower temperature during sperm production.

Seminiferous tubules

• Reside in testes and produce sperm

• allow sperm to move into the epididymis

testes

• Primary reproductive organ in men

• testes are tubular glands located in a pouch-like structure called the scrotum

vas deferens

Thick-walled tube in the male reproductive system that transports sperm cells from the epididymis, where the sperm are stored prior to ejaculation.

sperm cells

reside on the perimeter of the tubules and mature as they enter the hollow portion or lumen

vas deferens

lined with smooth muscle which can perform rhythmic contractions during ejaculation which help to move the sperm to the prostatic duct.

prostate gland

gland located inferior to the bladder

seminal vesicle

vesicle located just posterior to the prostate gland

seminal vesicle

produces fluids which help to nourish the sperm

prostate gland

produces an alkaline fluid to help move the sperm along.

prostatic, membranous, and penile urethras.

what are the sections of urethra in males?

urethra

Sperm pass though the prostatic duct to the

corpora cavernosa

• The penis contains 2 columns of tissue called

• deep arteries in each that transport blood during an erection which is under parasympathetic control.

corpora spongiosum

• the penis contains 1 column called

• contains the urethra.

spermatogenesis

• Sperm cells develop by way of

• Here a spermatogonium matures under the influence of hormones and becomes a primary spermatocyte.

diploid cell

what is the primary spermatocyte that contains the full 46 chromosomes called?

matures into a secondary spermatocyte

what happens to the primary spermatocyte during meiosis?

23

how many chromosomes does each secondary spermatocyte?

haploid cell

what is a secondary spermatocyte that contains only 23 chromosomes called?

testosterone

what is the primary male reproductive hormone?

testosterone

moderates the development of the male reproductive system during fetal development and then again during puberty where it completes maturation of the male

hypothalamus and anterior pituitary

testosterone is secreted in response to hormones from the

Gonadotropin

• hormone secreted by the hypothalamus

• promotes the secretion of follicle stimulating and luteinizing hormones from the anterior pituitary gland.

testosterone

• feeds back to the hypothalamus to inhibit the secretion of gonadotropin releasing hormone.

• helps to regulate testosterone levels

cervix

• connects the body of the uterus to the vagina.

• at the tip of the uterus

• Part of the lining contains glands that make and release mucus that stops sperm from entering the uterus during pregnancy and period.

Fallopian tubes

• The female structures that transport the ova from the ovary to the uterus each month.

• In the presence of sperm and fertilization, the uterine tubes transport the fertilized egg to the uterus for implantation.

Ovarian follicles (Graafian follicles)

• Are rounded enclosures for the developing ova in the cortex near the surface of the ovary, providing for the maturation and release of a fertilizable oocyte (ovum),

• forms the corpus luteum, which promotes and maintains implantation of the embryo.

ovaries

• The primary female reproductive organs, or gonads,

• 2

uterus

• also known as the womb,

• female reproductive organ that is responsible for many functions in the processes of implantation, gestation, menstruation, and labor.

vagina

has 3 main functions:

• provides a passageway for blood and mucosal tissue from the uterus during a woman’s monthly period.

• receives the penis during sexual intercourse and holds the sperm until they pass into the uterus.

• provides a passageway for childbirth.

ovaries

• primary reproductive system organs in the female

• contain the oocytes which mature during the ovarian cycle.

oogenesis

oocytes within the ovaries develop by way of a process called?

diploid

what is the primary oocyte in female called?

46

how many chromosomes does oocytes contain?

23

how many chromosomes does a haploid secondary oocyte have?

fimbrae

The fallopian tube connects to the ovary by way of finger like projections called?

outer perimetrium, middle smooth muscle myometrium layer and inner endometrium

what are the layers of the uterus?

inner endometrium

the layer of the uterus that is eliminated during menstruation.

Graafian Follicle

A mature follicle in women

estrogen and progesterone

what hormones does follicles secrete as it matures?

estrogen and progesterone

hormones that Both work to enlarge the endometrium and supply it with blood vessels to make it ready for potential implantation of a fertilized oocyte.

female menstrual cycle

luteinizing hormone

causes ovulation whereby the follicle releases the oocyte from the ovary.

estrogen

the primary female hormone and works to first develop the female reproductive system in utero and then finishes maturation of the female during puberty.

testosterone

• The role of is to promote muscle development,

• bone growth,

• the development of secondary sex characteristics,

• maintaining libido (sex drive) in both males and females.

zygote

a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.

blastocyst

• A fertilized oocyte or zygote (single cell) will develop into a …… (group of cells) that travels through the fallopian tube to the uterus for implantation. 

• (50–75 percent) fail to implant

• shed with the endometrium

outer layer of the blastocyst or trophoblast

secretes human chorionic gonadotrophin (hCG) hormone which directs the corpus luteum to survive, enlarge, and continue producing progesterone and estrogen to suppress menses.
