ANAT 3: Anatomy of Ovaries, Uterus and Testes Flashcards
What hormone is responsible for maintaining pregnancy in females?
What Produces it?
Progesterone produced by Corpus Leuteum
What are the 3 times the cervix opens?
Ovulation, Menstruation, Birth
Inner mucous coat of uterus shed during menstruation if no conception
Endometrium
Smooth muscle of uterus
Myometrium
Serosa of Uterus
PERImetrium
Broad Ligamament of Uterus
PARAmetrium
____________ has a multilayer epithelium with glycoprotein that only allows one sperm to fertilize and egg
Secondary Follicle
Unit of Oocyte+ helper cells
Follicle
Oocytes migrate from _____________ of the ovary to _____________
Oocytes migrate from PERIPHERY of the ovary to INSIDE
Significance of uterine tubes?
site of fertilization and allows passage of oocyte
sperm reservoir=> sperm bind to the ciliated surface of uterine tubes
Can fertilize 4-5 days after intercourse
Expulsion of the mature oocyte to the abdominal cavity?
What Collects the mature Oocyte?
Ovulation
It is collected by the trumpet-shaped distal end of the uterine tube
(infundibulum) with fimbriae
What day of the menstrual cycle do women Ovulate?
Days 11-14
_____________ add secretions to male ejaculate in the __________ containing __________ to fuel sperm and ______ to maintain their shape
Prostate/Seminal Vesicles add secretions to male ejaculate via the VAS DEFERNS containing Fructose/Glucose to fuel sperm and Salt to maintain their shape
Sperm production only viable at what temp
32 C
How long deos sperm productrion take?
62-64 days
What can impact sperm quality?
Inflammation/flu any other illness in the body can impact sperm quality
So too can Stress (Cortisol)
Role of the Bulbourethral Gland?
Adds very viscous secretions => Lubricaiton
Each testis is partially surrounded by two tunics:
* Outer visceral & parietal layers (______) formed from the peritoneum
- Inner capsule (___________) formed from fibrous connective tissue
Each testis is partially surrounded by two tunics:
Outer visceral & parietal layers (tunica vaginalis) formed from the peritoneum

________ is a ligament connecting the gonad to the future scrotum
Gubernaculum is a ligament connecting the gonad to the future scrotum
Superficial ring vs. deep ring Inguinal canals?
Superficial ring: slit formed by external oblique muscle
Deep ring: slit formed by transversus abdominis muscle
Progression of Spermatogenesis?
Spermatogonia
- Spermatocytes I
- Spermatocytes II
- Round spermatids
- Elongated spermatids
- Spermatozoa
