  1. Female reproductive system cells

  2. Ovary • Periotoneal (outer surface) • May also be called the germinal epithelium (does not contain germ cells) • Pseudostratifiedcuboidal to columnar mesothelium • Offers protection to the outer surface • Ovarian stromal cells (bulk of the ovary) • Spindle-shaped, arranged in a whorled texture • Secretes estrogen

  3. Ovary • Follicles – within the cortex of the ovarian stroma • Each follicle contains an oocyte surrounded by granulosa cells • Oocyte is the egg – discussed in the lecture on gamete cells • Granulosa cells – stratified cuboidal cells • Become the corona radiata around the egg • Process and release estrogen

  4. Fallopian Tubes • The elaborately folded mucosa is lined with ciliated columnar epithelium • Conducts the egg from the ovary to the uterus • Mucus cells provide lubrication for ease of movement • Muscular Layer • For structure and some peristaltic movement

  5. Uterus • Endometrium • Simple columnar epithelium • Stratum Functionalis: superficial layer sloughed off during menstruation; appears untidy (unfinished); • Stratum Basalis: replenishes the stratum functionalis after the excretory phase of menstruation • Myometrium • Multilayers of smooth muscle that are in poorly defined layers • Contracts to expel the endometrium during menses or expel a baby during parturition

  6. Uterus

  7. Cervix • Between the uterus and vagina • Transitions from simple columnar cells to nonkeratinized stratified squamous • The transition allows for considerable stretching during childbirth • Surrounded by smooth muscular fibers interwoven with elastic fibers • Offers some contractile ability during childbirth

  8. Vagina • Passage from the cervix to the outside of the body • Non-keratinized stratified squamous epithelium • These cells accumulate large amounts of glycogen • This causes the cells to appear empty upon staining • Surrounded by smooth muscular fibers interwoven with elastic fibers • Offers some contractile ability during childbirth

  9. Mammary Gland • When inactive, the mammary tissue appears to consists of ducts, which are separated by fibrous connective tissue and adipose cells. • During pregnancy, the ducts extend and the secretory glands enlarge • Each secretory unit is surrounded by myoepithelial cells • Secretory cells resemble mucous cells (except they expel milk – not mucous) • Work to excrete the milk during lactation • Bands of smooth muscle cells found in the subcutaneous tissue – especially around the nipple

  10. Mammary Gland Inactive Active
