And some examples of connective tissue include bones, blood, tendons, cartilage as well as adipose tissue. And the final type of tissue in the human body is the nervous tissue. So the individual cells of the nervous tissue are known as nerve cells or simply neurons. And these nerve cells are responsible for generating action potential, our electrical signals that basically allow the cells to communicate with one another and will focus more on what an action potential is when we'll discuss the nervous system of the human body. Now, these are the four different types of tissues and a tissue is basically individual cells that are organized to carry a specific type to carry out a specific type of function. Now the question is, what exactly is found in between these cells in our tissue?
