Reproductive system Flashcards
Identify bulbourethral gland, corpus spongiosum, and spongy urethra.
Identify urinary bladder, prostate gland, and ureter.
Identify urinary bladder, prostatic urethra, corpus spongiosum, penile urethra, corpus cavernosum, and glans penis
Identify cremaster muscle, spermatic cord, epididymis, testis, and scrotum.
Identify cremaster muslce, epididymis, prepuce, and glans penis.
Identify broad ligament, ovary, fimbriae of uterine tube, and fundus of uterus.
Identify uterus, cervix, vaginal orifice, clitoris, labia majora, urethral orifice, labia minora
Primary Oocyte: looks like a water balloon with the knot facing you. Notice primordial follicle: primary oocyte is surrounded by a single, flat layer of cells.
Primary follicle: cell layer increases in size in primary oocyte and so a primary follicle is a primary oocyte surrounded by >1 layer of cells. Look for space between oocyte and cells (zona pellucida).
Secondary follicle: adds fluid filled vescles (look a bit disorganized) inside and thecal cells outside entire structure; zona pllucida still surrounds the oocyte.
Mature/Graafian follicle: one clean vesicle. Larger, note the oocyte gravitates toward one side. Last stage before ovulation.
Identify the corpus luteum. What does it do?
Identify the corpus albicans.
Secretes progesterone and some estrogen; If pregnancy occurs, it enlarges, otherwise it degenerates after 10-12 days. It is the next step of the follicle after ovulation. Corpus albicans is the last follicular stage before next cycle.
What are the stages of follicular maturation?
- Primary oocyte
- Primary follicle
- Secondary follicle
- Mature follicle (Graafian follicle)
- Ovulation
- Corpus luteum
- Corpus albicans
Identify the mentrual phase, proliferative phase, and secretory phase. When does ovulation occur?
Ovulation occurs between the proliferative and secretory phases.
During which phase does the endometrium layer slough off due to decreased progesterone secretion?
Menstrual phase
