MUSKULOSKELETAL SYSTEM (The muscles)

MUSCLES:

Muscle is a soft tissue in the body of humans and animals that produces force and motion.

Muscles are responsible for maintaining posture, physical movement (sitting, walking, eating, etc), and movement of internal organs (such as keeping the heart pumping to circulate blood and moving food through the digestive system).

TYPES OF MUSCLES:

Cardiac and Smooth muscles are INVOLUNTARY muscles. We don't decide when to use them.

Skeletal muscles are VOLUNTARY muscles. We use them when we want.

  

THE SKELETON

GAMES TO PRACTISE:

Label the skeleton 1

Label the skeleton 2

Label the bones

MUSCULOSKELETAL SYSTEM (the skeleton, joints, ligaments and tendons)

Check the spelling on your notebooks to learn the words properly.

Learn how to pronounce the names of the bones:

JOINTS:

Joints are where two bones meet. They make the skeleton flexible — without them, the movement would be impossible.

We can classify them into the three groups: FIXED (skull), SEMI-MOVEABLE (spine) and MOVEABLE (knee).

Some joints to learn:

LIGAMENTS AND TENDONS:

Ligament - a connective tissue (strong bands) that connect bones to bones at the joint. Ligaments are ELASTIC fibers.

Tendon – a connective tissue attaching muscle to bone. Tendons are NON-ELASTIC fibers.
