E2 Reproductive Female

Question 1

Anatomy of the Female reproductive systems includes

Answer 1

Anatomy:

1. Ovary
2. Fallopian tube
3. Uterus
4. Cervix/vagina
5. Breast

Question 2

Ovary:

Describe structure & function

Answer 2

Function:

• Oogenesis: Production of Haploid female gametes (ova)
• Sex hormones synthesis: Estrogen & Progesterone

Structure:

1. Cortex

• Epithelium
• Tunica albuginea (CT)
• Developing follicles: Primordial follicles (oocyte) surrounded by a single layer of flat granulosa cells

2. Medulla
   * Blood vessels

Question 3

Ovary Cortex

Describe the state of the ovary cortex at birth

Answer 3

Outer cortex:

•Primordial follicles (Oocytes)

• •Fixed number(~400,000)
• •Quiescent: (arrested in development)
• Surrounded by a single layer of flat follicular cells
• Stroma: spindle-shaped fibroblasts

Question 4

Describe the process of follicle selection

Answer 4

FSH triggers a subset of follicles to develop further

• Dominant follicle selection (one w/ highest quantity of FSH receptors) & ovulate
• Rest die (undergo atresia)
