I: Histology Flashcards
_____ phase: acquisition of fertilization and motility in the epididymis
Maturational
_____ phase: acrosomal vesicles migrate to one pole of the nucleus.
Cap
_____ phase: centriole extends away from the nucleus to form the flagellum, inactive centriole becomes neckpiece
Acrosomal
_____ phase: Golgi apparatus gives rise to large acrosomal vesicles
Golgi
_____ phase: spermatids undergo morphologic changes and mature into spermatozoa
Spermiogenic
_____ phase: spermatocytes reduce chromosome number by half
Meiotic
_____ phase: spermatogonia give rise to spermatocytes
Proliferative
_____: a residual body produced by degeneration of the corpus luteum if implantation does not occur
Corpus albicans
_____: granulosa and theca cells that are remodeled into a cluster of endocrine cells following ovulation
Corpus Luteum
70% of all mature sperm are stored in the _______.
Cauda epididymis
Name the four phases of spermiogenesis.
Golgi; Cap; Acrosomal; Maturational
Name the three phases of spermatogenesis.
Proliferative, Meiotic, Spermiogenic
Name the three zones of the Fallopian tubes.
Infundibulum, Ampulla, Isthmus
Primary follicles acquire layers of _____ cells that comprise the ______.
Granulosa, Corona Radiata
Primordial follicles become primary follicles when follicular cells become ______.

When do oogonia enter meiosis I?
5 months gestation
When is the first polar body released in female gametogenesis?
Hours before ovulation
Which cell type? Haploid male gametes at different stages of nuclear condensation
Spermatids
Which cell type? Large nuclei with clearly observable chromosomal components; 4C; male
Primary spermatocytes
Which cell type? Male progenitors that have committed to undergoing meiosis
Type B spermatogonia
Which cell type? Spermatocytes undergoin meiosis II; not commonly seen due to short phase
Secondary spermatoctyes
Which cell type? True male stem cells that can divide mitotically
Type A spermatogonia
Which cells in the seminiferous tubules have pale cytoplasm and small, darkly-staining nucleoli?
Sertoli
Which structure? Contributes fluid to semen via the urethra; pseudostratified columnar epithelium
Prostate Gland
Which structure? Large tortuous regions of secretory cells embedded in fibromuscular stroma
Seminal Vesicle
Which structure? Paired glands with highly irregular extensions of tissue with pseudostratified columnar epithelium
Seminal Vesicle
Which testicular structure? 20 tubules leading from the Rete testis to the epididymis
Ductili efferentes
Which testicular structure? Anastomosing channels with myoid cells that contract to propel sperm through channels
Rete testis
Which testicular structure? Form highly coiled coni vasculosi outside the testes, merging into a single epididymal duct
Ductili efferentes
Which testicular structure? Has three muscular layers innervated by sympathetic innervation, columnar epithelium with microvillar surface
Vas deferense
Which testicular structure? Pseudostratified columnar epithelium with microvilli, 2-4 layers of smooth muscle
Epididymis
