Lessons 1. Muscular System Go Go 2. Diseases and Disorders Go Go

Table of Contents  Please get out your MUSCULAR SYSTEM PACKET

Table of Contents  Look through the packet… ◦ HIGH LIGHT or UNDERLINE terms that you aren’t familiar with... (origin, spindle, antagonist, etc)

Table of Contents

 The muscular system contains over 600 muscles.  The muscular system performs these functions: ▫Helps with body movement ▫Supports body posture ▫Produces heat and energy ▫Protects internal organs ▫Helps move blood, food, and waste products through the body ▫Opens and closes body openings

Table of Contents  All muscles have four common traits: ▫Excitability or Irritability ▫Contractibility ▫Extensibility ▫Elasticity  Muscle tone

Table of Contents  Excitability or Irritability: Ability to respond to a stimulus, such as a nerve or hormone Contractibility: Ability to shorten and produce movement when stimulated  Extensibility: The ability to be stretched and lengthen.  Elasticity: The ability to return to its original shape after contracting or stretching

Table of Contents  Ability of muscles to be slightly contracted at all times, even when not in use. It allows a person to be in a state of readiness to act.

Table of Contents  Cardiac: muscle forms the walls of the heart  Visceral: or smooth, muscle is found in hollow organs  Skeletal: muscle is attached to the bones

Table of Contents  Involuntary Muscles: muscle responds on it’s own (ex. Cardiac and Visceral)  Voluntary Muscles: a person can control their actions (skeletal)

Table of Contents  Tendons: Connects muscle to bone  Origin: connected to the bone that does not move  Insertion: connected to the bone that moves when the muscle contracts  Fascia: fibrous tissue that wraps around an individual muscle

Table of Contents  Flexion  Extension  Abduction  Adduction  Rotation

Table of Contents  Loss of muscle tone can result from serious illness or injury  Lack of muscle use can result in: ▫Atrophy : Reduction in size and strength ▫Contracture: Severe tightening of muscle results in permanent bending of a joint

Table of Contents  GOOGLE … POKE-A-MUSCLE  COMPLETE ALL LEVELS…  SHOW ME YOUR SCORE WHEN COMPLETE  Must get at least an 80%

Table of Contents  A sheath of fibrous elastic tissue surrounding a muscle  Within the muscle  Tissue that surrounds each muscle fiber  Contains capillaries and nerves

Table of Contents  Sheath of connective tissue surrounding a bundle of muscle fibers

Table of Contents  Sheath of connective tissue surrounding a bundle of muscle fibers

Table of Contents  Myo = Muscle  Cyte = Cell

Table of Contents  I WANT YOUR OPINION…  Do you want to take the muscular system/Skeletal system test BEFORE Spring Break or AFTER? ◦ BEFORE = LESS TO TEST ON (ANATOMY OF MUSCLE AND SKELETON + INJURIES) ◦ AFTER = MORE ON TEST (ANATOMY OF MUSCLE AND SKELETON + Injuries + IDENTIFY MUSCLES)

Table of Contents  A series of bands visible along the muscle fibers  Peripheral nuclei = nucleus

Table of Contents

 TUESDAY = JEAPORDY  WINNING TEAM GETS EXTRA CREDIT  WEDNESDAY = SKELETAL SYSTEM AND MUSCULAR SYSTEM TEST  THURSDAY AND FRIDAY = WATCHING Patch Adams

Table of Contents  What are your plans for spring break?  IF YOU DON’T HAVE ANY MAKE SOME!  DO SOMETHING FUN!

Table of Contents  BOTH Muscular System packets ◦ Thumbs up/ down ◦ Muscle identification  Skeleton labeling packet… ◦ Packet with the anatomy of the bone broken down (Find on last page)

AntagonistAgonist  The muscles that oppose the agonist  Ex. Knee flexion = Quadriceps  The muscle that provides the major force to complete the movement  Ex. Knee flexion = hamstring

EccentricConcentric  Muscles not only ‘shorten’ but can also lengthen under load or tension  Ex. Squat exercise, the quadriceps muscles  Any contraction where the muscle shortens under load or tension

Table of Contents  Muscles don’t move (shorten or lengthen) at all to contract or develop tension  Ex. Wall sits

Table of Contents  States that bone grows and remodels in response to the forces that are placed upon it  Muscles help the shape of the bone ◦ Due to the movements and forces caused by muscles

Table of Contents  Muscle Strain: Torn or stretched muscles or tendons  Fibromaylgia: muscle disorders with chronic pain in specific muscle sites.  Muscular Dystrophy: a group of inherited diseases in which the muscles gradually atrophy, or waste away

Table of Contents  SIT ANYWHERE…  Get out all skeletal and muscular system notes  REVIEW individually, partner or in a group  PREP FOR JEAPORDY REVIEW  WINNING TEAM = 5 points EXTRA CREDIT

Table of Contents  First to buzz in gets to answer… MUST PROVIDE AN ANSWER (THIS PERSON DOES NOT GET TO RE-ANSWER)  IF ANSWER IS WRONG… First to buzz in gets to steal the question AND CONVERSE WITH THEIR GROUP MEMBERS for 60 seconds (YOU CAN USE YOUR NOTES)  IF NO ONE KNOWS THE ANSWER… First to buzz after 5 second count down  Same procedure as if question answered wrong

Table of Contents  Last minute prep, review, questions, etc  All you need is a pen or pencil
