It is called a joint. Joints are also called articulations, they are strong connections that join the bones, teeth, and cartilage of the body to one another. Each joint is specialized in its shape and structural components to control the range of motion between the parts that it connects. Joint is usually formed of fibrous connective tissue and cartilage, they may be grouped according to the type of motion: ball and socket joint, hinge joint, condyloid joint, which permits all forms of angular movement except axial rotation, pivot joint, gliding joint, or saddle joint.
The two organisms that are most closely related according to Linnaean taxonomy are <em>Felis catus</em> and <em>Panthera pardalis</em>, because they belong to the same family
<h3>What is taxonomic classification?</h3>
Linnaean system of classification consists of a hierarchy of groupings called taxon. Each taxon is arranged in a hierarchical order.
The hierarchical arrangement of the taxon are as follows:
- Kingdom
- Phylum/Division
- Class
- Order
- Family
- Genus
- Species
These taxa are arranged from the most inclusive to the most exclusive i.e. members of the same species are the most closely related in that order.
This suggests that <em>Felis catus</em> and <em>Panthera pardalis</em> are the most closely related because they belong to the same family.
