Study Notes
Genetic Conditions
- Genetic conditions are caused by changes in DNA
- Carcinogens are substances that cause cancer
- Sex-linked genes are located on sex chromosomes (X and Y)
- Males are more likely to express recessive X-linked traits
Puberty
- Puberty is a period of physical changes that lead to sexual maturity
- Hormones (e.g., FSH and testosterone) trigger puberty
- Gonads (testes in males, ovaries in females) are the primary reproductive organs
Male Reproduction
- Sperm production occurs in the testes
- Sperm maturation and storage occur in the epididymis and vas deferens
- Seminal fluid is created by accessory glands
- Sperm count varies per ejaculate
Female Reproduction
- Ovary produces eggs (ova)
- Hormonal changes (FSH, estrogen, progesterone) regulate egg maturation and ovulation
- Follicle stimulating hormone (FSH) and estrogen are important for regulating female reproductive health
Menstrual Cycle
- A monthly cycle of hormonal changes in the female reproductive system
- Hormones regulate follicle growth, ovulation, and uterine lining development
- Menstruation is shedding of uterine lining if no fertilization occurs
- Ovulation typically occurs mid-cycle
Fertilization
- Fusion of sperm and egg resulting in a zygote
- Fertilization usually occurs in the fallopian tubes
- The zygote develops into an embryo and implants in the uterine wall
Pregnancy
- Pregnancy involves development of a fetus in the uterus
- Amniotic sac, placenta and umbilical cord support the developing fetus
- Labor involves uterine contractions that push the fetus out of the body
