1. Chapter 5: The Muscular System Section 1
Lesson 5.1
Muscle Tissue Categories and Functions Remember that this power point does not take the place of reading and taking notes from your book chapter.

2. Muscle Tissue categories functions skeletal smooth cardiac
behavioral properties
tension and types of skeletal muscle contractions

3. Muscle Tissue Categories
skeletal
voluntary
striated
smooth
involuntary
no striations
cardiac
intercalated disks

4. Muscle Tissue Categories

5. Skeletal Muscle Organization
sarcolemma and endomysium surrounds the muscle fiber
perimysium bundles groups of muscle fibers to make up a fascicle
epimysium encloses several fascicles to make up a muscle
aponeurosis connects muscle to other tissues

6. Skeletal Muscle Organization

7. Review and Assessment
True or False? 1. Smooth muscle is voluntary. 2. Cardiac muscle has branching fibers. 3. Smooth muscle is multinucleate. 4. Perimysium wraps fascicles to make a muscle. 5. Endomysium surrounds the muscle fibers.

8. Behavioral Properties of Muscle
extensibility–stretch
elasticity–snap back
irritability–respond
contractility–shorten

9. Muscle Tissue Functions
tension and types of skeletal muscle contraction
agonist–moves bone
antagonist–opposes the movement of the agonist

10. Concentric Contraction
agonist contracts, antagonist relaxes

11. Eccentric Contraction
agonist contracts while lengthening, antagonist relaxes

12. Isometric Contraction
both agonist and antagonist contract

13. Review and Assessment
Match these words with 1–5 below: extensibility, elasticity, irritability, contractility, agonist, antagonist. 1. respond 2. opposes movement 3. stretch 4. shorten 5. causes movement
