Reproductive Systems Flashcards
(17 cards)
Primary sex organ for men
Testes.
Primary sex organ for women
Ovaries.
Testes
In the scrotum, Sperm production and secretion of hormones, Divided into lobules containing seminiferous tubules, the site of spermatogenesis .
Epididymis
Sperm maturation and storage, Comma-shaped, consists of a head, body, and tail .
Ductus Deferens
Transport of sperm during ejaculation, Part of the spermatic cord, joining with the seminal vesicle to form the ejaculatory duct.
Accessory Glands
Nourishment of sperm, Secretes a fluid that enhances sperm motility.
Penis
Copulatory organ, delivering sperm into the female reproductive tract, Includes the root, body, glans, spongy urethra, and erectile tissues (corpus spongiosum and corpora cavernosa)
Spermatogenesis
Seminiferous tubules of the testes, Sperm cells undergo meiotic division and maturation. Sertoli cells nourish developing sperm, while interstitial cells secrete testosterone.
Sperm Pathway
1.Released into the lumen of seminiferous tubules
2.Transported through rete testis to the epididymis where flagella activate
3.Stored in the epididymis until ejaculation .
Ovaries
Lateral sides of the uterus, Production of ova and secretion of hormones, Supported by the mesovarium, broad ligament, suspensory ligament, and ovarian ligament.
Uterine Tubes (Fallopian Tubes)
Site of fertilization, transport of ova, Isthmus, ampulla (site of fertilization), infundibulum, and fimbriae.
Uterus
Receives, retains, and nourishes fertilized eggs, Divided into the fundus, body, and cervix. Composed of three layers: perimetrium (outer), myometrium (middle), and endometrium (inner).
Vagina
Passage for delivery of infants, receives penis and semen during intercourse
Oogenesis
In the ovaries, Production of ova involves the division and maturation of oogonia. Unlike males, females have a finite number of germ cells that do not replenish after birth.
Menstrual Cycle
Shedding (menstruation), proliferative (pre-ovulation), and secretory (post-ovulation), Preparation of the female body for potential pregnancy and shedding of the endometrium if fertilization does not occur.
Follicle-Stimulating Hormone (FSH)
In Females: Stimulates growth of ovarian follicles
In Males: Supports spermatogenesis
Luteinizing Hormone (LH)
In Females: Triggers ovulation and development of the corpus luteum
In Males: Stimulates testosterone production by interstitial cells
