Compare and Contrast the Structural Characteristics of the 3 different types of muscular tissue.
| Short Answer Question
Both cardiac and skeleton muscle tissues are striated and smooth muscle is not. Skeletal muscle is voluntarily controlled and autonomic, while both cardiac and smooth muscle tissues are involuntary and autorhythmic. Cardiac muscle cells usually only have one central nucleus, and are branched. Smooth muscle cells communicate via gap junctions.
69
Chuck has a rotator cuff injury. Which muscles and associated structures are most commonly involved in this type of injury? What sorts of activites commonly cause this injury?
| Short Answer Question
The tendon of the **subscapularis**, **supraspinatus**, **infraspinatus**, and **teres minor** make up the rotator cuff. The most commonly injured structure of the rotator cuff is the tendon of the ***supraspinatus*** muscle. Any activity involving ***vigorous circumduction*** of shoulder can result in a rotor cuff injury. Common examples of activitites that lead to this injury includes throwing baseballs, playing racket sports, and swimming.
70
Briefly describe 4 main benefits of stretching before exercising?
| Short Answer Question
Stretching can improve physical performance by **increasing joint flexibility** allowing the joint to move through a greater range of motion. Stretching **decreases risk of injury** by decreasing resistance in various soft tissues so there is less of a chance of exceeding maximum tissue extensibility during activity. Stretching can **reduce some of the muscle soreness** that result after exercise. Stretching can help **realign soft tissuses** to improve and maintain good posture.

| Difference in Muscle Tissue
**Smooth** - Non-Striated, 1 nucleus, Involuntary/Autonomic, continuous contractions
**Cardiac** - Striated, 1-2 nuclei, Involuntary/Autonomic, forceful contractions
**Skeletal** - Striated, Multinucleated, Voluntary/Somatic, autorythmic, forceful contractions
72
What Are The 4 muscles and surrounding tendons of the rotator cuff?
**Supraspinatus** - located above shoulder, helps raise arm
**Infraspinatus** - located below the suprasinatus, helps rotate the arm outward
**teres minor** - located below the infraspinatus, helps rotate the arm outward
**Subscapularis** - located on the front of the shoulder blade, helps rotate the arm inward
