• MUSCOLO SKELETAL SYSTEMConsists of bones, joints, and muscles that provide form, support and stability, and the ability to move.

• MUSCLE TISSUE

• SKELETON BONES

• CONNECTIVE TISSUE

• SKELETAL MUSCLES

• SMOOTH MUSCLE

• CARDIAC MUSCLE

• INTERNAL ORGANSe.g. blood vessels, hair follicles, urinary tract, genital tract, digestive tract.SMOOTH MUSCLE tissue contracts more slowly than skeletal muscle, but for longer periods of time. They are also INVOLUNTARY

• HEARTis responsible for creating action that pumps blood from the heart to the rest of the body. It is INVOLUNTARY directed by the automatic nervous system.

• ATTACHED TO BONES BY TENDONS & OTHER TISSUES most prevalent muscles type in the human body, 30-40% of body weight. They are VOLUNTARY as the brain tells them what to do.

• TENDONS

• Skeletal muscle fibre connects directly through tissue fibres.

• LIGAMENTS

• Bones themselves are bound tightly together with other bones.

• CARTILAGE

• Tissue at the ends of bones, preventing bones from grinding against each other.

• STRIPED

• STRIATED

• MAJOR MUSCLE GROUPS

• 1

• 2

• POSTERIOR

• ANTERIOR

• (BACK)- erector spinae- rhomboids- gluteals- hamstring- calf muscles

• (FRONT)- quadriceps- rotator cuff- abdominals- pectoral

• 3

• MUSCLE CONTRACTION (MUSCLES PULL: NEVER PUSH)

• ISOMETRIC (STATIC)

• ECCENTRIC (LENGTHENING)

• CONCENTRIC (SHORTENING)

• AGONIST- primarily responsible for movement

• ANTAGONIST- counteracts the agonist, lengthening

• 4

• MUSCLE ORIGINS & INSERTIONS

• ORIGIN

• INSERTION

• The point where muscle attaches to more stationary of the bones of the axial skeleton.

• The point where muscle attaches to bone that is moved most.
