Which term refers to the ridge of cartilage at the top of the head in some lop-eared breeds?

The term "crown" refers to the ridge of cartilage at the top of the head in certain lop-eared breeds of rabbits. This feature is significant as it contributes to the distinct appearance of these breeds, often influencing their aesthetic appeal in competitions and exhibitions. The crown can affect the overall balance and conformity of the rabbit's head structure, which is important for breeders and judges when evaluating the animal's adherence to breed standards. Understanding the anatomy of rabbits, including the role of features like the crown, is essential for those involved in breeding and showing rabbits.

Other terms such as "cull" relate to the selective breeding process where animals are discarded from breeding stock for various reasons; "crossbreed" denotes a rabbit born from two different breeds; and "cobble" typically describes a specific body type. These options provide context regarding breeding practices or physical characteristics but do not pertain to the specific anatomical feature described in the question.
