    Insights

    Finger and palm print patterns, known as dermatoglyphs, form early in pregnancy. These patterns are valuable for diagnosing and studying skeletal dysplasias, including syndactyly and symphalangism.

    Area of Science:

    • Developmental biology
    • Genetics
    • Orthopedics

    Background:

    • Finger and palm print patterns (dermatoglyphs) emerge during early fetal development, coinciding with limb morphogenesis.
    • Their formation is influenced by the developing surface contours of the palms and soles.

    Purpose of the Study:

    • To explore the utility of dermatoglyphs in the context of skeletal dysplasias.
    • To highlight their role in identifying and analyzing conditions like syndactyly and symphalangism.

    Main Methods:

    • Observational analysis of dermatoglyphic patterns.
    • Correlation of dermatoglyphic findings with skeletal dysplasia diagnoses.

    Main Results:

    • Dermatoglyphs aid in detecting and studying syndactyly and symphalangism.
    • These patterns can help determine the onset and progression of skeletal dysplasias.
    • Asymmetry in dermatoglyphs can be demonstrated and dated, offering diagnostic insights.

    Conclusions:

    • Dermatoglyphs serve as a valuable tool in the diagnosis and understanding of skeletal dysplasias.
    • Specific dermatoglyphic features can provide key diagnostic information for certain genetic and developmental conditions.

    Cytoskeletal Linker Proteins - Plakins01:09

    Cytoskeletal Linker Proteins - Plakins

    Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...
    Desmosomes01:05

    Desmosomes

    The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...
    Bone Markings01:26

    Bone Markings

    Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
    Articulating Projections
    Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
    Bone Formation by Intramembranous Ossification01:29

    Bone Formation by Intramembranous Ossification

    Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
    The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
    Sutures of the Skull01:22

    Sutures of the Skull

    The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
    Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
    Changes in the Appendicular Skeleton with Age01:09

    Changes in the Appendicular Skeleton with Age

    The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
    Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
