Study Notes
Reproductive System Symbols
- The female symbol resembles a mirror, representing femininity rooted in ancient Greek and Roman mythology.
- The male symbol depicts armor and a spear, emphasizing strength and protection.
Female Reproductive System
- Right ovary plays a key role in egg production.
- Fimbriae of the fallopian tube help guide the egg into the tube.
- The fallopian tube is vital for fertilization; the widest area (ampulla) is where male and female gametes unite.
- The uterus is essential for pregnancy, with separate layers:
- Endometrium: inner lining, thickens for implantation.
- Myometrium: muscular layer aiding in contractions.
- Perimetrium: outer protective layer.
- Ovarian ligament connects ovaries to the uterus, supporting their position.
- Broad ligament provides additional support to reproductive organs.
- Cervix serves as a passage between the vagina and uterus, with two meanings (neck-like structure).
- Vaginal canal features a zigzag shape to increase surface area and accommodate childbirth.
Male Reproductive System
- Mnemonic "7UP" helps remember key structures:
- S: Seminiferous tubules.
- E: Epididymis.
- V: Vas deferens.
- E: Ejaculatory duct.
- U: Urethra.
- P: Penis.
- Scrotum houses the testicles, regulating temperature for sperm production.
- Seminiferous tubules produce sperm within the testicle.
- Epididymis stores mature sperm.
- Vas deferens serves as the duct transporting sperm to the ejaculatory duct.
- Urethra carries urine and sperm, differentiated into prostatic and penile sections.
- Penile structure includes the glans penis, which is sensitive and crucial for copulation.
Gametes and Gonads
- Gonads: ovaries (female) and testicles (male); produce gametes.
- Gametes: ovum (female) and sperm (male).
- Mitosis results in two identical daughter cells; meiosis results in four non-identical haploid cells.
Meiosis Overview
- Meiosis consists of two rounds of division leading to genetic diversity through crossover in prophase I.
- Begins with diploid cells (2n) and ends with haploid cells (n).
Spermatogenesis
- Process starts with spermatogonium, leading to primary spermatocyte, then two secondary spermatocytes, each producing two sperm.
- End result: four genetically diverse sperms, with half carrying X and half carrying Y chromosomes.
Oogenesis
- Oogenesis produces one ovum from one oogonium, with polar bodies resulting from meiotic divisions.
- The ovum retains most cytoplasm to nourish the future zygote, while sperm provides only nuclear material.
Fertilization
- Fertilization occurs when sperm meets the secondary oocyte, which is arrested at metaphase II, signaling the readiness for potential fertilization.
