Study Notes
Male Reproductive System
- The urethra is a tube that passes through the penis, carrying urine and sperm.
- The penis is the external sexual organ that delivers sperm to the female reproductive system. It has erectile tissue that stiffens during ejaculation.
- Testes produce sperm cells.
- Sperm are stored in the coiled epididymis.
- The vas deferens carries sperm from the epididymis to the urethra.
- The scrotum houses and protects the testes, keeping the temperature slightly lower for sperm survival.
- Seminal vesicles secrete a fluid to nourish sperm.
- Ejaculatory ducts contract during ejaculation to expel semen.
Sperm and Semen
- Sperm are produced in the testes and stored in the epididymis.
- Sperm mix with fluids from glands (prostate and seminal vesicles) to form semen.
- Semen is transported through the urethra and expelled during ejaculation.
Female Reproductive System
- Ovaries are almond-shaped organs that produce hormones (estrogen and progesterone) and egg cells.
- Ovulation occurs approximately every 28 days.
- Fallopian tubes receive the egg and are where fertilization may occur.
- The uterus is a muscular organ where a fertilized egg develops.
- The cervix connects the uterus to the vagina.
- The vagina is a hollow tube connecting the cervix to the external body.
- The vulva is the external female genitalia including the mons veneris, labia majora, labia minora, and clitoris.
Hormonal Regulation in Reproductive Systems
- Hormones regulate the reproductive systems, impacting puberty, ovulation, pregnancy, and development.
- Testes produce testosterone, influencing male sex organs, secondary sexual characteristics, and sex drive.
- Ovaries produce estrogen and progesterone, influencing female secondary sexual characteristics, sex drive, and the menstrual cycle.
- The pituitary gland releases follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin.
Menstrual Cycle
- The menstrual cycle is the monthly shedding of the uterine lining.
- The cycle begins with the maturation of an egg in the ovary.
- If fertilization doesn't occur, the uterine lining sheds (menstruation).
Development of Life
- Gametogenesis is the formation of sperm and egg cells.
- Fertilization occurs when the sperm joins the egg.
- The fertilized egg divides and forms a blastocyst.
- Gastrulation is where three germ layers form, developing into organs.
- Organs acquire their structure and function.
Endocrine and Nervous Systems Overview
- The endocrine system uses glands that secrete hormones directly into the bloodstream.
- Hormones regulate the body's activities, development, and internal balance.
- The hypothalamus, pituitary, adrenal, and thyroid glands are examples.
Early Human Development
- Fertilization unites sperm and egg to form a zygote, which travels through the fallopian tube.
- Within a week a blastocyst and then a morula are formed, and these settle in the uterus.
- The umbilical cord and placenta support the developing embryo from the uterine wall.
Positive Feedback Mechanisms
- Positive feedback amplifies processes to achieve a goal.
- Blood clotting and uterine contractions during childbirth are examples.
Homeostasis and Feedback Mechanisms
- Homeostasis maintains the body's internal stability.
- Negative feedback mechanisms reduce changes to restore balance.
- Pancreas releases insulin to lower blood sugar, and glucagon to raise it.
Heritable Mutations in Sex Cells
- Mutations are changes in genetic material.
- Mutagens are physical or chemical factors that disrupt DNA.
- Somatic mutations occur in non-reproductive cells, not passed to offspring.
- Germinal mutations occur in sex cells, potentially passed to offspring.
- Chromosome mutations involve changes in chromosome structure or numbers.
Human Genetic Syndromes
- Genetic syndromes result from chromosomal abnormalities leading to physical and mental defects.
- Examples: Cri du chat, Williams syndrome, Down syndrome, Edward syndrome, Patau's syndrome, Klinefelter's syndrome, and Turner's syndrome.
Impact of Mutations
- Germ cell mutations are inherited, whereas somatic mutations are not.
- Some mutations can be beneficial to a species, while others are harmful.
- Common causes of mutations include smoking, old age, chemotherapy, and radiation or hazardous chemicals.
