The branchial skeleton, including gill rakers, pharyngeal teeth, and branchial bones, serves as the primary site of food processing in most fish. Here we describe a protocol to dissect and flat-mount this internal skeleton in threespine sticklebacks. This method is also applicable to a variety of other fish species.

Carbon Skeletons

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side chains...

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Overview of the Axial Skeleton

The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs. The axial skeleton of the adult...

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...
FAQs
Normalization to the analyzed tissue area makes the measurement a density rather than a raw vessel-length value. This allows vessel centerline content to be compared between image regions that differ in size. In practice, the resulting value summarizes how much vascular network is represented within each defined area, while preserving a compact basis for comparing conditions.
Skeletonization converts each segmented vessel into a one-pixel-wide centerline, making the network's represented path length easier to quantify than the original vessel shapes. This reduction focuses the analysis on centerline structure, so measured skeleton pixels or length reflects the amount and arrangement of vessel network captured in the image.
When Vessel Skeleton Density changes between conditions, the result can indicate altered vascular organization or network abundance. In neuroscience, such differences may be associated with angiogenesis, vascular degeneration, perfusion-related remodeling, or broader neurovascular health. The metric therefore supports structural comparisons across tissue states, including normal and pathological contexts.
An image-based workflow begins with microscopy images from a defined tissue area. Vessels are segmented from the image, the segmented structures are reduced to one-pixel-wide skeletons, and the skeleton length or pixel count is measured relative to that area. The resulting normalized value can then be compared across regions or experimental conditions to examine vascular differences.
In cerebral tissue, Vessel Skeleton Density can characterize microvascular architecture in selected regions such as the cortex and brain lesions. Quantifying centerline structure within those regions provides a way to compare vascular patterns across tissue contexts. The measure therefore supports neuroscience studies focused on regional organization and lesion-associated vascular change.
Because the measure can be compared across conditions, it is useful in studies of development, aging, and neurological disease. A difference in density can help identify altered vascular organization or network abundance in the tissue examined. Researchers can use these comparisons to investigate angiogenesis, vascular degeneration, or perfusion-related remodeling as structural features of neurovascular health.
