  • 7. FIGURE 3–2 Physiologic changes leading to onset of puberty. A, In females, and B, in males. Solid lines illustrate stimulation of hormone production, and broken lines illustrate inhibition. Through a neurotransmitter the central nervous system stimulates the hypothalamus, which in turn produces a gonadotropin-releasing factor that causes the anterior pituitary to produce gonadotropins (FSH or LH). These hormones stimulate specific structures in the gonads to secrete steroid hormones (estrogen, progesterone, or testosterone). The rise in pituitary hormone increases hypothalamus activity. Elevated steroid hormone levels stimulate the central nervous system and pituitary gland to inhibit hormone production.

    Summarize the significant changes in growth and development of the fetus in utero at 4, 6, 12, 16, 20, 24, 28, 36, and 40 weeks’ gestation.
  • 46. Mitosis
    Process of cellular division
    Results in daughter cells that are exact copies of the original cell
    Identical to parent cell and to each other
    Contain a full set of chromosomes or genetic material
    Refered to as diploid cells
    Somatic cells continue to reproduce and replace each other
  • 47. Mitosis
    The cell undergoes several changes ending in cell division
    At the last phase of cell division, a furrow develops in the cell cytoplasm
    The parent cell divides into two daughter cells
    Each daughter cell has its own nucleus
    They are identical to the parent cell
    They have the same diploid number of chromosomes (46) and same genetic makeup as the cell from which they came
  • 48. Meiosis
    Type of cell division that produces reproductive cells called gametes (sperm and ova) - each cell contains half genetic material of parent cell (haploid)
  • 49. Meiosis (cont’d)
    Meiosis consists of two successive cell divisions
    First division: Chromosomes replicate
    Second division: Chromatids of each chromosome separate and move to opposite poles of each of the daughter cells
    Cellular division results in formation of four cells
    Each cell contains haploid number of chromosomes
    Daughter cells contain only half the DNA of normal somatic cell
  • 50. Comparison of Meiosis and Mitosis
  • 51. FIGURE 7–1 Gametogenesis involves meiosis within the ovary and testis. A, During meiosis, eachoogonium produces a single haploid ovum once some cytoplasm moves into the polar bodies.B, Each spermatogonium produces four haploid spermatozoa.
  • 52. Oogenesis
    Process that produces the female gamete, called an ovum (egg), that begins to develop early in the fetal life of the female
    Ovaries begin to develop early in the fetal life of the female
    All ova that female will produce in her lifetime are present at birth - ovary gives rise to oogonial cells, which develop into oocytes
    During puberty: Mature primary oocyte continues through first meiotic division in ovary
    Haploid cells released at ovulalion
  • 53. Oogenesis
    The first meiotic division
    Two cells of unequal size produced with same number of chromosomes
    One cell is secondary oocyte, other is minute polar body
    Secondary oocyte and polar body each contain 22 double-structured autosomal chromosomes and one double-structured sex chromosome (X)
    During puberty: Mature primary oocyte continues through first meiotic division in ovary
  • 54. Spermatogenesis
    Production of the male gamete, or sperm, during puberty
    The spermatogonium (primordial germ cell)
    Begins with complete set of genetic material - diploid number of chromosomes
    Cell replicates before it enters first meiotic division
    Cell is now primary spermatocyte
    During second meiotic division, divide to form four spemiatids, each with haploid number of chromosomes
  • 55. Spermatogenesis (cont’d)
    During the first meiotic division
    Spermatogonium forms two cells called secondary spermatocytes
    Each contains 22 double-structured autosomal chromosomes and either double-structured X sex chromosome or double-structured Y sex chromosome
  • 56. Preparation for Fertilization
    Preparation is the first component of fertilization
    Ovum released into fallopian tube - viable for 24 hours
    Sperm deposited into vagina - viable for 48 to 72 hours (highly fertile for 24 hours)
    Sperm must undergo capacitation and acrosomal reaction
    Sperm penetration causes a chemical reaction that blocks more sperm penetration
  • 57. Moment of Fertilization
    Sperm penetration causes chemical reaction that blocks more sperm penetration
    Sperm enters ovum, chemical signal prompts secondary oocyte to complete second meiotic division
    True moment of fertilization occurs as nuclei unite
    Chromosomes pair up to produce diploid zygote
    Each nucleus contains haploid number of chromosomes (23)
  • 58. Moment of Fertilization (cont’d)
    Union restores diploid number (46)
    Zygote contains new combination of genetic material
    Sex of zygote determined at moment of fertilization
    Two chromosomes of twenty-third pair (sex chromosomes) - either XX or XY - determine sex of individual
    Females have two X chromosomes, males have an X and a Y chromosome

The erosion of the endometrium by the syncytiotrophoblast is ongoing. B, Implantation is completed by day 9, and extraembryonic mesoderm is beginning to from a discrete layer beneath the cytotrophoblast. C, By day 16 the embryo shows all three germ layers, a yolk sac, and an allantois (an out pouching of the yolk sac that forms the structural basis of the body stalk, or umbilical cord). The cytotrophoblast and associated mesoderm have become the chorion, and chorionic villi are developing.

Fetal blood flows through the umbilical arteries into the villous capillaries of the placenta and returns through the umbilical vein to the fetal circulation.
  • 76. FIGURE 7–11 Fetal circulation. Blood leaves the placenta and enters the fetus through the umbilicalvein. After circulating through the fetus, the blood returns to the placenta through the umbilical arteries. The ductus venosus, the foramen ovale, and the ductus arteriosus allow the blood to bypass the fetal liver and lungs.

    Single placenta
  • 80. Identical Twins
    Number of amnions and chorions present - depends on timing of division
    Division within 3 days of fertilization; two embryos, two amnions, and two chorions will develop
    Division about 5 days after fertilization
    Two embryos develop with separate amniotic sacs
    Sacs will eventually be covered by a common chorion
    Monochorionic-diamniotic placenta
