Spermatogenesis And Oogenesis 0.0 / 5 ? MedicineGrowth and Development UniversityNone Created by: HedleyBaulfCreated on: 19-05-16 12:03 38642517 Across 1. Provide nutrients to the growing sperm cells and help remove unwanted cytoplasm. (7, 5) 7. Process by which female gametes are produced in the ovaries. Unlike in males, all the primary oocytes are produced during foetal development. (9) Down 2. Precursor stem cells. During foetal development, they differentiate into primary oocytes. (8) 3. Once sperm cells are produced in the seminiferous tubules they move into a region of highly convoluted tubules called the epididymus, where sperm cells mature and are stored until release. (5, 5) 4. Spermatogonium -> Primary Spermatocyte -> Secondary Spermatocyte -> Spermatids -> Sperm Cells (7, 7) 5. Found on interstitrum; release testosterone which stimulates the stem cell to differentiate into the diploid primary spermatocyte. (6, 5) 6. Occurs within seminiferous tubules of the testes. Inside the walls of these tubules are precursor stem cells (Spermatogonium: Diploid -> Give rise to future sperm cells) (15) 8. Oogonium (2n) -> Primary Oocyte (2n) -> Secondary Oocyte (n) -> Ovum (n) (7, 7)
