Reproductive System - Module 17 Flashcards
Reproductive System
System responsible for producing Oocytes
Female Reproductive System
Organs of Female Reproductive System
Ovaries, Oviducts, Uterus, Cervix, Vagina, Vulva
Primary female sex organs that produces ovum and several steroid hormones
Ovaries
Layers of Ovary
Germinal Epithelium
T. albuginea
Stroma (medulla & cortex)
Large fluid-filled follicle that ruptures to release the secondary oocyte
Graafian Follicle
Process called in the releasing of Secondary Oocyte from the Graafian follicle
Ovulation
Remnant of the ruptured follicle that produces progesterone, estrogen, and relaxin
Corpus Luteum
Scar like tissue that has degenerated
Corpus Albicans
Process of forming oogonia
Oogenesis
How many oogonia does a woman produce in her lifetime
400 mature over a woman’s lifetime
Primary oocyte and single layer of follicular cells
Primordial Follicle
2 cells that forms two layers of Ovarian stroma
Theca interna (secretes hormone)
Theca externa (connective tissue)
Follicle Development
Primordial Follicle
Primary Follicle
Secondary Follicle
Graafian Follicle
Corpus Luteum
this follicle is one layer of squamous like follicles that surrounds the oocyte
Primordial Follicle
This follicle is two or more layers of cuboidal granulosa cells that encloses the oocyte
Primary Follicle
This follicle contains fluid-filled space between granulosa cells that coalesces to form a central antrum
Secondary Follicle
Secondary follicle at its most mature stage that bulges from surface of ovary
Graafian Follicle
What hormone is secreted by the corpus luteum to maintain the wall of uterus during early period of development
Progesterone
This structure receives the ovulated oocyte and provides site of fertilization
Uterine Tube
Finger-like projections of infundibulum
Fimbriae
Organ that is about the shape and size of an inverted Pear
Uterus
Segments of Uterus
Fundus (Domed upper portion)
Body (Main portion)
Cervix (Narrow lower section)
Layers of the Uterus
Endometrium
Myometrium
Perimetrium
What is the epithelia lining of Endometrium
Simple Columnar Epithelium
2 layers of Endometrium
Stratum functionalis and Stratum basalis
What layer of endometrium is shed during menstruation
S. functionalis
How many layers of smooth muscle does Myometrium have
3 layers of smooth muscle
Visceral Peritoneum of Uterus
Perimetrium
What layer of endometrium replaces the S. functionalis each month
S. basalis
Phase in endometrium where glands and blood vessels scatters throughout the functional zone
Proliferative Phase
Phase in endometrium where glands are enlarged and have branches preparing endometrium for implantation
Secretory Phase
Three coats of Vagina
Fibroelastic Adventitia
Smooth Muscle
Stratified Squamous Mucosa
What is mucosa near the vaginal orifice that forms an incomplete partition
Hymen
Organ known as the Birth Canal
Vagina
True or False, lower pH of vagina = less susceptibility to infection and less hospitable for sperm
True
Accessory Organs of female reproductive system that are modified sweat glands; lies over the pectoralis major muscles
Mammary Glands
What ligaments of mammary gland is attached to Fascia
Suspensory ligaments (of cooper)
How many lobes are there in Mammary Glands
15-20 lobes
What system is responsible for genesis of spermatocytes and steroid hormones
Male Reproductive System
What Dense Connective Tissue capsule surrounds the testes
T. vaginalis
Thickened posterior surface of testis that forms Mediastinum testis
T. albuginea
How many pyramidal compartments (Testicular Lobules) are there
Around 250 pyramidal compartments
Structure functions particularly for spermatocytogenesis
Seminiferous Tubules
How many seminiferous tubules are in each testicle
250 to 1000
Straight tubules of Seminiferous Tubules
Tubuli recti
Tubules connecting the seminiferous tubules to an anastomosing labyrinth of epithelium-lined channels
Tubuli recti
how many dutuli efferentes connects rete testis to cephalic portion of epididymis
10 - 20
Lining of Seminiferous Tubules
Germinal or Seminiferous Epithelium
Process of generating Spermatozoa
Spermatogenesis
Process of spermatozoa maturation
Spermiogenesis
Secondary spermatocyte containing half of the chromosomes
Spermatid
In the Golgi phase of sperm maturation, these are small periodic granules that accumulates in Golgi complex
Proacrosomal Granules
Are elongated pyramidal cells that partially envelop cells of the spermatogenic lineage
Sertoli Cells
Are the the collective term for Tubuli recti, Rete testis, Ductuli efferentes
Intratesticular Genital Ducts
Tubuli recti empty into the ___________
Rete testis
What are the Excretory Genital Ducts in Male reproductive System
Ductus epididymis
Ductus deferens
Urethra
Single highly coiled tube of the male reproductive system
Ductus epididymis
Long, branched, and irregular microvilli in the Vas deferens
Stereocilia
Dilated region of ductus deferens before entering the Prostate
