Chapter 4, Problem 1MC

Use the key to classify each of the following described tissue types into one of the four major tissue categories.

Key: (a) connective tissue (c) muscle

(b) epithelium (d) nervous tissue

_____(1) Tissue type composed largely of nonliving extracellular matrix; important in protection and support

_____(2) The tissue immediately responsible for body movement

_____(3) The tissue that enables us to be aware of the external environment and to react to it

_____(4) The tissue that lines body cavities and covers surfaces

Summary Introduction

To review:

The classification of four major type of tissues on the basis of their specific characters, into different categories.

Solution:

The classification of tissue types into major categories of the tissue:

Tissue type	Category
(1) Tissue type is composed largely of a nonliving extracellular matrix; important in protection as well as support.	(a) Connective Tissue
(2) The tissue immediately responsible for the body movement.	(c) Muscles
(3) The tissue enables us to be aware of the external environment as well as to react to it.	(d) Nervous tissue
(4.) The tissue that lines the body cavity and covers surfaces.	(b) Epithelium

Explanation of Solution

1. The connective tissues are important in providing protection and support to the body. They are composed largely of the nonliving extracellular matrix.

2. The body movements occur due to the relaxation or contraction of the muscle fibers in the human body.

3. The nervous tissues are the tissues that are mainly responsible for receiving the stimulus from various sources and react according to them. Hence, they make the body of the individual aware of the external environment.

4. The epithelial cells are the cells that line up the body cavities and form the outer covering.

Conclusion

Thus it is concluded that connective tissue, muscles, nervous tissue and epithelium are four major categories of tissues that plays specific and vital role in the body as explained above.
