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 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".
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
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")
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")
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").
