    Study Notes

    Bone Types

    • Flat Bones: Characterized by a thin, flattened shape; examples include the skull bones and sternum.
    • Irregular Bones: Non-standard shapes that cannot be categorized into other bone types; includes vertebrae and facial bones.

    Skeletal Terminology

    • Foramen: Refers to a hole in a bone, such as the foramen magnum.
    • Fossa: A depression or hollow area in a bone; an example is the glenoid fossa.
    • Process: A projection or protrusion on a bone, like the mastoid process.

    Imaging Techniques

    • Computed Tomography (CT) Scans: Effective for cancer staging and guiding biopsies.
    • CT-guided Needle Biopsy: A specific technique using CT scans to direct a needle into a tumor for biopsy purposes.

    Acetabulum

    • The hip socket formed by the hip bone, crucial for hip joint stability and movement.

    Pelvic Comparison

    • The male pelvis generally has a narrower shape compared to the wider, more circular female pelvis, optimized for childbirth.

    Lower Limb Bones

    • Chondrocytes: Cells that reside in a lacunae, contributing to cartilage. These cells are surrounded by a cartilage matrix.
    • Cartilage Matrix Composition: Contains collagen fibers for structural strength and proteoglycans for resilience.
