PHYSIOLOGY REPRODUCTION
Growth and Aging • Puberty ( GnRH) • in girls = menarche • Average 12 y • In boys, later (harder to pinpoint a time) • Menopause • Irregular menstrual periods and cessation • Andropause • Similar drop in androgens
Spermatogenesis • Seminiferous tubules • Sertoli cells: androgen binding protein blood testes barrier etc. • Leydig cells testosterone vs. DHT
The ampulla, fimbriae, and infundibulum are anatomical features of the • Uterus • Cervix • Vagina • Fallopian tubes
The epithelium cells that produce sperm cells are located in the testes within the • Seminiferous tubules • Vas deferens • Corpus spongiosum • Ampulla • Prostate Gland
The chromosomes of a sperm cell are contained • Within the flagellum • Packed in the head of the cell • Within the acrosome of the cell • In the neck of the sperm cell
Secretions of the seminal vesicle • Are alkaline • Pass into the testes • Are acidic • Contain sperm cells
On average the process of ovulation occurs every • 2-3 days • 14-15 days • 28-30 days • 8-9 months
Development of the embryo takes place in the tissue layer of the uterus known as the • Perimetrium • Endometrium • Myometrium • Neurometrium
