Testis
Testis the seminiferous tubules ("c") and the tunica albuginea ("a").
Testis the rete testis. The arrow points into the lumen of the tubule
Testis epithelium of the rete testis
Testis the lumen of the efferent ductules
Seminiferous Tubule the seminiferous tubules ("ST"). Note the tunic of fibrous connective tissue, and stratified epithelium ("SE"). Maturing sperm cells can be seen in the lumen of the tubules, showing their aggregated tails ("Ta").
Seminiferous Tubule
Seminiferous Tubule Epithelium spermatogonia ("Sg") spermatocytes ("Sc") spermatids ("Sd") which then differentiate into spermatozoa ("Ta"). The nurturing Sertoli cells ("Se")
Seminiferous Tubule Epithelium spermatogonia cell at the tip of the pointer The tubule wall is labeled "a". Primary spermatocytes are labeled "b". Secondary spermatocytes are located in zone "c". Mature spermatozoa form in area "d".
Seminiferous Tubule Epithelium Sertoli cells
Seminiferous Tubule Epithelium interstitial cells
Spermatozoa head region ("HR" in slide 1) and a tail region. The tail region is further divided into a neck, middle piece ("MP"), principal piece ("PP"), and end piece ("EP")
Spermatozoa mass of spermatozoa (labeled "a") is shown to the right of the epithelium. The epithelium of the ductus epididymis is a ciliated columnar type ("b" identifies the cilia of this epithelium). Finally, "c", the darker red area to the left, is a connective tissue supporting layer for the epithelium
Ductus Epididymis two lumen ("Lu"). Dense aggregations of spermatozoa ("Sp") connective tissue ("CT")
Ductus Epididymis the tubular aspect of epididymis
Epididymis Epithelium pseudostratified epithelium ("Ep") long microvilli ("Mv") a tail ("Ta") Residual cytoplasm ("RC") cell borders ("CB") smooth muscle ("SM") underlying the epithelium.
Epididymis Epithelium the stereocilia of the epithelium
Ductus Deferens three layers of smooth muscle ("SM") adventitia ("Ad") blood vessels ("BV"), columnar epithelium ("Ep") supported by an underlying lamina propria ("LP") The lumen ("Lu")
Ductus Deferens arrow pointing to the lumen
Seminal Vesicle outpocketings ("Ou") highly folded ("Fo")
Seminal Vesicle
Seminal Vesicle
Seminal Vesicle
Seminal Vesicle
Seminal Vesicle columnar epithelium
Prostate Gland
Prostate Gland the arrow pointing to a prostatic accretion
Prostate Gland the secretory epithelium in the prostate, which is typically columnar
Penis
Penis the vascular spaces found in the erectile tissue and also shows the urethra ("a") imbedded in the corpus spongiosum
Penis an infection on the surface
Female Reproductive System
Vulva
Vulva labia majora are being retracted to reveal a cancer of the vulva.
Vagina It has a thick inner mucosal layer ("ML" in slide 1 surrounding the inner cavity, the lumen "Lu"), stratified squamous epithelium and an underlying lamina propria, containing blood vessels ("BV")
Vagina the inner epithelium of a vagina with the arrow pointing to a nucleus in one of the cells near the surface
Vagina
Uterus The endometrium ("En") lumen ("Lu") and consists of an epithelium of simple columnar cells. myometrium ("My") blood vessels ("BV") serosal layer ("Se")
Uterus intrauterine device (I.U.D.) implanted in the lumen of the uterus for contraception
Uterus severely prolapsed uterus that is protruding out of the vaginal opening
Endometrium
Endometrium the endometrial lining of a uterus
Endometrium arrow points to a coiled secretory gland of the endometrium
Endometrium the arrow points at glycogen secretion droplets which will serve as food for the implanting embryo
Fallopian Tube inner mucosa ("ML"), an intermediate muscularis layer consisting of circularly and longitudinally arranged smooth muscle ("SM") and an outer serosal layer ("Se") composed of connective tissue. The highly folded inner mucosa layer consists of an epithelial layer ("Ep") that covers a thin connective tissue lamina propria ("LP"). The numerous mucosal folds ("MF")
Fallopian Tube uterine portion of the fallopian tube (at the arrow).
Oviduct Epithelium shows the epithelium of the oviduct consists of columnar cells, many of which have cilia (Ci) on their free surfaces. The non-ciliated or secretory cells ("SC")
Oviduct Epithelium cilia which are indicated by the arrow
ovary central medulla ("Me") and outer cortex ("Co"). blood vessels ("BV"), mesovarium ("Mo"). secondary follicles ("SF"). Also visible are corpus lutea ("CL"),
ovary developing follicles ("b"), stromal blood vessels ("c"), and ("a") a developing corpus luteum
Follicles tissue stroma ("St") in the cortex of the ovary contains primordial and primary follicles ("PF") as well as larger secondary follicles ("SF")
Follicles follicles ("b") which have been generated by the germinal epithelium ("a")
Graafian Follicle/Corpus Luteum zona pellucida ("ZP") membrana granulosa ("MG"). discus proligerus ("DP"), the corona radiata ("CR").
Graafian Follicle/Corpus Luteum zona pellucida (at the arrow), the coronal radiata ("a"), the follicle cells of the membrana granulosa layer ("b"), and an outer theca layer ("c")
Graafian Follicle/Corpus Luteum a ruptured bloodied follicle called the corpus hemorrhagicum
Graafian Follicle/Corpus Luteum post-ovulatory follicle
Graafian Follicle/Corpus Luteum transformation of the corpus hemorrhagicum into a corpus luteum. The clot is being absorbed by the remaining follicular cells and there is enlargement to form the corpus luteum (labeled as "a").
