5.5 Histology of the Female Reproductive System Flashcards
Surface epithelium of ovaries
Simple cuboidal epithelium aka germinal epithelium
Responsible for whitish color of the ovary
Tunica albuginea
Tunica albuginea is composed of _______ connective tissue
Dense connective tissue
Ovarian parenchyma has two layers namely
Cortex and medulla
Part of the ovarian parenchyma that contains highly cellular CT and ovarian follicles
Cortex
Part of the ovarian parenchyma that contains loose CT and blood vessels
Medulla
Correct order of follicular growth and development phases
Primordial - unilaminar primary - multi laminar primary - secondary / antral - mature/ graafian - ovulation
In the beginning of puberty, pituitary gland releases which hormone
FSH
The primordial follicle contains chromosomes in which meiosis stage
First meiotic prophase
Follicular Stage which form simple cuboidal epithelium around the primary oocyte
Unilaminar primary follicle
Follicular stage where granulosa cells are first formed
Multilaminar primary follicle
Epithelium of multilaminar primary follicle
Stratified cuboidal
Follicular stage characterized by complete zona pellucida
Multilaminar primary follicle
ZP1-ZP4 functions to
Binding proteins on sperm surface to induce acrosomal activation
Follicular stage characterized by accumulation of follicular fluid or liquor folliculi
Antral follicle
Vascularized endocrine tissue that secretes androstenedione
Theca interna
Cells that aromatize the steroid into estradiol
Theca cells
Thecal layer with smooth muscle and fibroblasts
Theca externa
Most developed stage of follicular growth
Graafian
Part of graafian follicle that protrudes into the antrum
Corpus oophorus
Accompanies the oocyte when it leaves the ovary
Corpus radiata
Phase where in Antrum increases in size and accumulates follicular fluid rapidly
Graafian
Graafian follicle develops from a primordial follicle in over a period of ____ days
90 days
Graafian follicle has ______ granulosa layer and _____ thecal layer
Thinner granulosa layer, thick thecal layers
How many chromosomes are there in a primary oocyte?
46 or 23 pairs, diploid cell
How many chromosomes are there in a secondary oocyte?
23, haploid
Primary follicles that do not mature undergo what process
Atresia - degeneration of ovarian follicles that do not ovulate during menstrual cycle
Primary oocytes are arrested at what stage
Prophase I
Secondary oocytes are arrested at what stage
Metaphase II
Final viable product of oogenesis
Ovum (haploid)
Before birth primordial germ cells differentiate into
Oogonium
Lining ep. of fallopian tube
Simple columnar ciliated ep
Most common site of ectopic pregnancy in fallopian tubes
Ampulla
Most common site of RUPTURED ectopic pregnancy in fallopian tubes
Isthmus
Addt’l innermost longitudinal layer of muscularis of fallopian tubes
Intramural
Mucosa of fallopian tubes is most prominent in which part
Ampulla
