Histology: Introduction to Muscle Tissue

Histology: Introduction to Muscle Tissue

Author: Aaron Mullally

- know what the three different muscle tissues are in the body

- know what the word contract means

- know what the word myocyte means

- know what the basic function of muscle tissue is

- know which muscles are voluntary and involuntary (unconscious)

This packet is designed to get you thinking about the histology of muscle tissue. In this you will learn what the three types of muscle are along with some new terminology. After this packet I will break down each type of muscle in separate packets. When you are finished with all three try writing down all of the differences between the three types of muscle without looking at a book or other information to practice what you learned.

Muscle Tissue Overview

Muscle tissue is composed of cells that contract to create movement. Always know that when you see the word contract you should think shorten. As the muscle cells within the tissue shorten they exert force on the tissues they are attached to (example: bone) which forces the tissue to move. The cells of muscle tissue are called myocytes. Even though myocytes come in different shapes and sizes they are all capable of contraction.

All three types of muscle contract to create movement and contain myocytes. The myocytes, however, come in different shapes and sizes. Know the different shapes of myocytes and how they are spaced will be the key to identifying the different muscles. Also, the shapes of the muscles correlate with how they physiologically work
