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.
