Neural Tissue
- Origin. Neural tissue develops from the ectoderm of the embryo. Except for microglia which develop from mesoderm.
- Special properties. The special properties of the cells of the neural tissues are excitability and conductivity. The cells of neural tissue are specialized for receiving stimuli and transmitting messages. Neural tissue consists of neurons and neuroglia.
Neural Tissue
All living organisms are made of cells. A unicellular organism has a single cell in its body, i.e., a single cell performs all basic life activities. However, in multicellular organisms, there are millions of cells. Most of these cells are specialized to carry out only a few functions efficiently. These functions are taken up by a distinct group of cells. Thus, it can be said that there is a division of labor in multicellular organisms.
A tissue is a group of cells that are similar in structure, origin, and function. The term ’tissue’ was given by Bichat. The branch of science dealing with the tissues is called ‘histology’. Mayer introduced the term histology. Malpighi is considered the “founder of histology. Broadly animal tissues are classified into four types: epithelial, connective, muscular, and neural.
