Lecture 34: Reproductive Flashcards
Be able to identify histological features of the testis from slides presented in class
Tunica albuginea: CT capsule surrounding testis. Mediastinum testis creates partitions.
Seminiferous tubules: highly convuluted,30-70 mm long-site spermatogenesis.
Intratesticular ducts:convey sperm to surface of testis. Tubuli recti: Simple columnar. Rete testis: simple cuboidal.
Extratesticular ducts: sperm to outside body
Glands: seminal vesicles, prostate, bulbourethral gland.
List the structures in order for sperm transport and describe the histology of the reproductive tract in males.
- Tubuli recti
- Rete testis
- Efferent ductules: simple columnar. Only mobile cilia in the entire duct system.
- Epididymis:tortuous and surrounded by CT. Pseudostratified columnar epithelium w/ basal and tall columnar cells w/ maybe stereociia.
- Vas deferens: lamina propria w/ elastic fibers. Passes into the prostate gland.
- ejaculatory duct: opens into the urethra on a thickened part of the urethral mucosa called the colliculus seminalis.
Be able to identify histological features of the testis and ducts from slides presented in class
K
Describe the changes that occur during the development of a mature ovarian follicle and relate timing w/ changes that occcur in the uterine lining during the menstrual cycle.
Puberty:diploid primary oocyte; secondary follicle w/ multiple layers of follicle cells and beginning of Antrim formation. 2 chromatids/chromosome. Haploid secondary oocyte + haploid polar body->tertiary follicle.
Ovulation: haploid secondary oocyte w/ corona radiata and thecal cells + haploid polar body. -meiosis resumes and is arrested at metaphase II
Describe the normal histology of the female reproductive tract and identify on slides presented in class
.k
Describe the changes that occur in the endometrium during the menstrual cycle
Day 5-14: uterine lining is rebuilding itself.
Day 14: ovulation
Day 14-27: secretory phase
w/o fert= ischemic-> menstrual phase
