Conscious and unconscious movements- how we move and how we control those movements

MOVEMENT

MOVEMENT

• Any movement within your body, either conscious or not, in response to a stimulus from the external environment or from a need noticed inside your body• Voluntary movement- movement of skeleton• Involuntary movement- digestion, heartbeat,

breathing

SYSTEMS INVOLVED

• Skeletal system• Provides structural support for body

• Muscular system• Moves bones (and others) to put body

into desired positions

TYPES OF MUSCLE

• Skeletal Muscle- attached to bones- directly moves body parts

• Smooth Muscle- line many organs- involuntary

• Cardiac Muscle- only in heart- pumps heart

MOVEMENT OF YOUR SKELETON- CONNECTIONS

• Tendons- connect muscle to bone• When muscle contracts, pulls bone

• Ligaments- bone to bone• Holds bones together

TYING IT ALL TOGETHER

• Cellular Respiration• Takes oxygen and glucose, makes ATP• ATP used to make muscles contract

• Muscles and other organs we’ve discussed• Lungs/diaphragm• Intestines/smooth muscle lining

CELLULAR RESPIRATION

• In Mitochondria• Glucose broken down• Bonds in glucose turned into ATP •Useable energy

• Remaining carbon from glucose exhaled as carbon dioxide

ORGANS RELYING ON MUSCLES

• Intestines• Muscles contract to cause food to be

pushed through• Blood vessels/capilaries• Muscles contract to open/close blood

vessels

PROCEDURES THAT HELP YOU

• ACL/MCL surgery• Rotator cuff • “Tommy John” procedures

ACL/MCL SURGERY

• Ligaments• Anterior cruciate and Medial Collateral

Ligaments• Similar to rubber

bands that holdbones together

ROTATOR CUFF

• Group of muscles and tendons that hold shoulder in place• With overuse or trauma, tendons can

tear• To fix, must drill holes in bone to restring

tendons (often taken from hamstring area)

TOMMY JOHN

• Baseball pitcher• Through repetitive twisting of elbow, frayed

UCL (ulnar collateral ligament)• Elbow surgery done to replace ligament

with tendon taken from somewhere else in body

DISEASES INVOLVING MOVEMENT

• MS vs. ALS• Tendinitis

MS VS. ALS

• MS attacks all neurons

• ALS attacks only motor neurons• Immune system attacks nerves,

preventing signal from being sent to muscles telling person to move

TENDINITIS

• Inflammation of tendons• Due to overuse of tendon

OR• Due to acute injury
