Study Notes
Female Reproductive System
- Consists of: ovaries, uterine tubes (oviducts/fallopian tubes), uterus, cervix, vagina, external genitalia, and associated glands
- Ovaries:
- Surface covered by a single layer of cells called the germinal epithelium
- Divided into outer cortex and inner medulla
- Cortex contains connective tissue stroma that houses ovarian follicles in various stages of development
- Medulla contains loose connective tissue and blood vessels
- Ovarian follicles:
- Primordial follicle: most primitive, composed of a single layer of squamous follicular cells (granulosa cells) surrounding the primary oocyte
- Primary follicle: follicular cells become cuboidal in shape, with 2 types (unilaminar and multilaminar) depending on the number of layers of follicular cells surrounding the primary oocyte
- Secondary (antral) follicle: similar to primary follicles, but with accumulations of liquor folliculi, forming a fluid-filled antrum
- Graafian (mature) follicle: undergoes ovulation, releasing the secondary oocyte from the graafian follicle
- Follicular atresia: degenerative process in which follicular cells and oocytes undergo apoptosis and removal by phagocytic cells
- Corpus hemorrhagicum and corpus luteum:
- Corpus hemorrhagicum: formed from the remnants of the graafian follicle, characterized by the presence of blood in its antrum
- Corpus luteum: a temporary endocrine gland secreting hormones (progesterone, estrogen, and relaxin)
- Oviducts (Fallopian Tubes):
- Lined by simple columnar epithelium with secretory and ciliated cells
- Act as a conduit for spermatozoa to reach the primary oocyte and to convey the fertilized egg to the uterus
- Regions: infundibulum, ampulla, isthmus, and intramural region
- Uterus:
- A muscular organ consisting of a fundus, body, and cervix
- Histologic structure: endometrium, myometrium, and perimetrium
Male Reproductive System
- Consists of: testes, intratesticular and extratesticular genital ducts, accessory glands, and penis
- Testes:
- Located in the scrotum
- Surrounded by an irregular DWFCT: tunica albuginea
- Divided into testicular lobules containing sparse CT with endocrine interstitial cells (Leydig cells) and seminiferous tubules
- Seminiferous tubules:
- Where sperm production occurs
- Sertoli (sustentacular) cells provide support, protection, and nutrition to developing spermatogenic cells, and produce and release androgen-binding protein (ABP) and the hormone inhibin
- Spermatogenesis:
- Process of producing haploid male gametes
- 3 phases: spermatocytogenesis, meiosis, and spermiogenesis
- Epididymis:
- Lined by pseudostratified columnar epithelium with stereocilia
- Regions: head, body, and tail
- Ductus (vas) deferens:
- Lined by pseudostratified columnar epithelium with stereocilia
- Delivers spermatozoa from tail of epididymis to ejaculatory duct
- Ejaculatory duct:
- Lined by simple columnar epithelium
- Delivers spermatozoa and seminal fluid to prostatic urethra
- Male accessory glands:
- Seminal vesicle: produces a viscous, yellow fructose-rich seminal fluid
- Prostate gland:
- Largest male accessory sex gland
- Consists of a varying number of individual tubuloalveolar glands
- 2 topographical parts: body (corpus prostatae) and disseminate part (pars disseminata prostatae)
- Bulbourethral gland (Cowper's gland): secretes a thick, slippery fluid containing galactose and sialic acid, coating and lubricating the urethra
Penis
- Composed of three columns of erectile tissue: dorsally (2 columns of corpora cavernosa) and ventrally (corpus spongiosum)
- 2 types: vascular and fibrous
