    Study Notes

    Human Reproductive Development and Lifecycle

    • Oogenesis and ovulation are controlled by FSH and LH, leading to cyclic changes in the ovaries during the ovarian cycle, which includes follicle development, ovulation, and corpus luteum formation.
    • Oocytogenetic cycle involves several steps from the migration of primordial germ cells to the start of puberty, where selected primary oocytes continue meiotic division.
    • Folliculogenesis, the development of follicles, consists of three phases: follicular, ovulatory, and luteal.
    • Spermatogenesis is the process by which spermatogonia are transformed into mature spermatozoa through stages of spermatocytogenesis, spermatidogenesis, and spermiogenesis.
    • Embryology involves the development of an embryo from fertilization to the fetal stage and is the study of the process and events in embryo development.
    • Oocyte and spermatozoon are the female and male gametes, respectively, involved in fertilization, which is the union of the male and female gametes.
    • The zygote is formed from the union of an oocyte and sperm and marks the beginning of a new human being.
    • Cleavage, morula, compaction, blastulation, blastocytes, and hatching are stages in the early development of the zygote.
    • Implantation refers to the attachment of the zygote to the uterine wall, and organogenesis is the process by which the ectoderm, endoderm, and mesoderm develop into the internal organs of the organism.
    • After the embryonic period, the developing human is referred to as a fetus, and infancy is the earliest period of extrauterine life.
    • Childhood is the period from about 13 months until puberty, and adolescence is characterized by rapid physical and sexual maturity.
    • Adulthood is generally reached between the ages of 18 and 21 years, and conception is the moment when a man's sperm successfully fertilizes a woman's egg, marking the start of pregnancy.

    Fungal Morphology and Classification

    • Septate hyaline hyphae and dark pigmented hyphae are observed in infected nails under a microscope
    • Mold reproductive spores, such as conidia and sporangiospores, are resistant to unfavorable conditions and easily disseminated in nature and laboratory settings
    • Asexual spores divide into four major groups: chlamydospores, arthroconidia, microconidia, and macroconidia, and are useful in identifying the mold genus and species
    • Mold spores, such as conidia and sporangiospores, are important for human health and can lead to rare fungal infections
    • Yeasts, also known as blastospores or blastoconidia, are large, unicellular cells that reproduce by budding and may form pseudohyphae
    • Some yeasts produce additional specific structures, such as germ tube formation, which is an initial step for true hyphae production
    • Yeasts grow best at 30-37°C and produce colonies on solid media, and their asexual forms are known as blastosores or buds
    • Yeasts can also produce sexual spores, such as basidiospores and ascospores, which are important for their reproduction
    • Fungi can grow in mold or yeast form according to environmental conditions, a phenomenon known as dimorphism
    • Fungi have subcellular structures including a cell wall, cell membrane, and cytoplasmic content, and produce slime/biofilm and capsules
    • The fungal cell membrane contains phospholipids, proteins, and sterols, mainly in the form of ergosterol, which is a target for antifungal drugs
    • Fungi are classified into groups based on sexual spore types and morphology of hyphae, such as Oomycota, Zygomycota, Ascomycota, and Basidiomycota, each with distinct characteristics and associations
