Lesson 1: Gametogenesis Flashcards
is the production of sperm from the primordial germ cell.
Spermatogenesis
3 STAGES OF SPERMATOGENESIS
- Spermatocytogenesis
- Meiosis
- Spermiogenesis
is the development of spermatogonia into primary spermatocytes.
Spermatogonia -> Spermatocyte
Spermatocytogenesis
the two successive cell division that the primary spermatocyte and their daughter cells respectively undergo to give rise to haploid cells called spermatids.
Primary -> Secondary
Spermatocyte -> Spermatids
Meiosis
Spermiogenesis
transformation of spermatids into spermatozoa.
Spermatids -> Spermatozoa
3 STAGES OF SPERM CAPACITATION
- Epididymal
- Ejaculation
- Capacitated
sperm matures in the epididymis and gains surface molecules.
Epididymal
he sperm with seminal plasma, which coats the sperm with protein.
Ejaculation
when exposed to the female tract,
Capacitated
are cells found outside the seminiferous tubules that generate testosterone.
Leydig Cells
provides nutrients to the developing sperm cell.
Sertoli Cells
is a condition where a male ejaculates a higher-than-normal volume of semen, typically greater than 5 milliliters.
Hyperspermia
is the process of formation of female gametes
Oogenesis
prevents next menstrual cycle since the egg cells are already out.
Corpus Luteum
signal to stop menstruation.
Progesterone
secretes androstenedione (precursor to testosterone).
Thecal Internal Cell
Granulosa Cell (aromatase)
converts testosterone into estrogen.
is a complex hormonal disorder that affects people with ovaries.
Polycystic Ovary Syndrome (PCOS)
