chondrocranium

9.9

Part of the skull made of cartilage that supports the brain in embryos and some animals

noun
/ˌkɒndrəˈkreɪniəm/

Specialized

: condrocráneo

The chondrocranium supports the brain in developing embryos, forming the initial structure of the skull.

Examples

The chondrocranium provided a supportive platform; additional support was provided by the splanchnocranium (yellow), particularly the epipterygoid bone.

Academic text (2003)
Branchial arches gave rise to the quadrate and articular bones, while the dermatocranium (pink) sheathed most of the chondrocranium (blue).

Academic text (2003)
In the autostylic architecture, the palatoquadrate is essentially fused to the chondrocranium.

Academic text (2003)
At this point in the evolutionary process, the palatoquadrate was completely fused with the chondrocranium to form a true autostylic jaw suspension, and it was covered almost entirely by dermal bone.

Academic text (2003)
Developed in the dermis and capable of beating rooted teeth, dermal bone was laid down over the entire original chondrocranium on the undersurface of the palatoquadrate and the anterior portion of Meckel's cartilage.

Academic text (2003)
In some fish, the chondrocranium is primarily cartilaginous, providing crucial support as they mature.
Studying the chondrocranium helps scientists understand how different species evolve their skull structures.

chondrocranium singular

chondrocrania plural

Morphology

chondrocranium = chondro- + cranium (opaque) = chondro + cranium

Although analyzable as 'chondro-' (cartilage) + 'cranium' (skull), the combining form 'chondro-' is technical and not familiar to average B1 learners, so the compound is not readily interpretable by them.

Etymology

Chondrocranium comes from the parts chondro- meaning 'cartilage' and cranium meaning 'skull'. So a chondrocranium is a 'cartilage skull' that forms in embryos or in some animals, like many fish, to support the brain.
