What iS the purpose of tissue in the nervous system?
The word tissue is derived from a Latin word meaning to "weave." Cells that make up tissues are sometimes "woven" together with extracellular fibers. Nervous tissue is the main component of the nervous system as it can be found in the brain, the spinal cord, and the nerves which regulate and control bodily functions. It is composed of nerve cells, and neuroglial cells, both of which contribute to nerve impulses within the body and contain nutrients used by the various cells.
Nervous tissue is made of nerve cells that come in many varieties, all of which are distinctly different.

What are the different types of tissues in the nervous system?
skeletal muscle tissue
Since the nervous system is connected to virtually every tissue within the body, due to the fact that it is responsible for how the brain understands bodily movements, it does not contain specific tissue matter. However, there are several main tissues within the body that are connected to the nervous system.
Muscle tissue is the most abundant of all of the tissues in living creatures. It is made up of "excitable" cells that are capable of contraction and relaxation.
There are three major types of muscle tissue:
Cardiac Muscle: This type of muscle is found in the heart. Muscle contraction allows the heart to beat.
Skeletal Muscle: It is attached to the bones and tendons and is associated with the body's voluntary movements. For example, if one were to flex their bicep, they would be contracting a skeletal muscle.
Visceral Muscle (or smooth muscle): Is found in various parts of the body such as the arteries, the bladder, the digestive tract and many other organs. It is a slower moving muscle, which means muscle contractions can be sustained for a longer period of time.

The nervous system also contains other important tissues, including connective tissue and epithelial tissue.
Connective Tissue: As the name implies, connective tissue supports and binds (eg. connects) other tissues together.

Epithelial Tissue: It is a membranous tissue covering internal organs and other internal surfaces of the body.

Nerve Tissue:
Tissue composed of neurons. Nervous tissue allows organisms to sense stimuli in both the internal and external environment.
