Module 4 Objectives
On completion of this module you should be able to:
1. Describe the functions and structures of the muscular system including muscle fibers, fascia, tendons, and the three types of muscles.
| 2. Recognize, define, spell, and pronounce the terms related to muscle movements and how muscles are named.
| 3. Recognize, define, pronounce, and spell the terms related to the pathology, and diagnostic and treatment proceedures of the muscular system
| THE MUSCULAR SYSTEM:
In this module you will learn to recognize, define, spell, and pronounce a number of medical terms. You will also be tested on information found in the topics below. Also study Chapter Four of your book for more information on these topics. Topics:

| Cover, support, and separate muscles.
| ten/o, tend/o, tendin/o
| Attach muscle to bone.
Muscles hold the body erect and make movement possible. Muscle movement generates nearly 85% of the heat that keeps the body warm. Muscles move food through the digestive system. Muscle movement such as walking, aids the flow of blood through veins as it returns to the heart. Muscle action moves fluids through ducts and tubes associated with other body systems. Muscles are composed of long, slender cells known as muscle fibers.
Fascia (FASH-ee-ah) is the sheet or band of fibrous connective tissue that covers, supports, and separates muscles.
A tendon is a narrow band of non-elastic, dense, fibrous connective tissue that attaches a muscle to a bone. For example, the Achilles tendon attaches the gastrocnemius muscle (the major muscle of the calf of the leg) to the heel bone. Be careful not to confuse tendons with ligaments. Ligaments connect one bone to another bone. Ligaments...
