Which of the following is NOT a type of connective tissue?

Neural tissue is not classified as a type of connective tissue. Instead, it is one of the four main types of biological tissue, along with epithelial tissue, muscle tissue, and connective tissue. Neural tissue is primarily responsible for transmitting electrical signals throughout the body and is primarily composed of neurons and glial cells.

In contrast, adipose tissue, bone, and cartilage are all types of connective tissue. Adipose tissue serves primarily as a fat storage site and helps insulate and protect organs. Bone is a rigid connective tissue that provides structure and support to the body while also enabling movement in conjunction with the muscular system. Cartilage is a flexible connective tissue that provides support and cushioning in various parts of the body, such as joints and the rib cage. Each of these tissues has distinct functions that fall under the umbrella of connective tissue types.
