Summary Introduction

The two basic types of cells in nervous tissue and their functional differences.

Introduction:

Humans and animals are the complex organisms made up of collection of cells to perform specific functions. These collections of cells are often called the tissues. Tissues arise from the embryonic origin that perform a specific physiological and structural role in an organ. Tissues perform specific functions, such as nerve signaling and nutrient digestion. There are four types of primary tissues namely epithelial, connective, nervous, and muscular tissues.

Excitability is a characteristic feature of all living organisms. Nervous and muscular tissues are the two excitable tissues that developed with a highest degree of all living things.
