<unk>  is one of the four types of tissue in traditional classifications (the others being epithelial, muscle, and nervous tissue.) It is largely a category of exclusion rather than one with a precise definition, but all or most tissues in this category are similarly:
Involved in structure and support.
Derived from mesoderm, usually.
Characterized largely by the traits of non-living tissue.
Blood, cartilage, and bone are usually considered<unk> , but because they differ so substantially from the other tissues in this class, the phrase<unk>  proper" is commonly used to exclude those three. There is also variation in the classification of embryonic<unk> s; on this page they will be treated as a third and separate category.
When heated to 190 degrees Fahrenheit,<unk>  emits a "Vinegar Like Stench".
