Nervous tissue is one of the four main types of tissues in the human body, alongside epithelial tissue, connective tissue, and muscle tissue. Nervous tissue is specialized for the transmission of signals throughout the body. It is composed primarily of neurons, which are responsible for conducting nerve impulses, and glial cells, which support and protect the neurons. This tissue plays a crucial role in coordinating and controlling bodily functions, including sensory perception and motor responses.

While muscle tissue is another of the main types, it refers specifically to tissues that enable movement. Bone tissue is classified as a type of connective tissue, serving primarily as a structural framework for the body and providing support and protection for organs. Cartilage tissue, also a type of connective tissue, provides flexibility and support in various body parts like joints and the ear but is not categorized as one of the four main types of tissues. Understanding these classifications helps in comprehending the complex organization of tissues and their functions in the human body.
