THE SKELETAL SYSTEM Movement is only possible thanks

THE SKELETAL SYSTEM Movement is only possible thanks to the interaction of Bones, Joints, and Muscles.

Every time you sprint through the halls because you're late for class or score against your opponents during a game, you’re using your bones, muscles, and joints. Without these important body parts, you would be unable to sit, stand, walk, or do any of the activities you do every day.

From our head to our toes, our bones provide support for our bodies and help form our shape. What does the skull protect? the brain …and the ribs? heart and lungs And the backbone? the spinal cord …and the pelvis? intestines and reproductive organs

Joints & Muscles - Joints are where two bones meet. - They make the skeleton flexible - without them, movement would be impossible. - Muscles are also necessary for movement: They're the masses of elastic tissue that pull our bones when we move. Together, our bones, muscles, and joints — along with tendons, ligaments, and cartilage — form our musculoskeletal system and allow us to move.

The skeleton has the following parts Skull Thorax Spine, backbone or vertebral column Upper limbs Lower limbs

The skull It is composed by a large group of bones which form a cavity where the brain lies and is protected.

The spinal cord It is a very important group of nerves and is protected by the spine. The spine, vertebral column or backbone has 24 articulating vertebrae and 9 or 8 fused vertebrae in the sacrum and the coccyx.

The thorax The ribs are elastic arches of bone. They are 12 on either side. They are connected behind with the vertebral column, and in front with the sternum. The sternum is a flat bone in the anterior wall of the thorax.

Upper limb The upper arm is a strong and thick bone called the humerus. It connects with the clavicle and the scapula The lower arm has two bones: the radius is on the outside of the body and is slightly larger; the ulna is closer to the body and slightly smaller. The hand bones are: the carpal, the metacarpals and the phalanges.

Lower limb The Hip bone consists of three bones: - Ilium - Pubis - Ischium The right and the left hip bones form the pelvis.

The upper leg is a strong and thick bone called the femur. The lower leg has two bones: the tibia and the fibula. The tibia is larger and stronger. The foot bones are: the tarsal, the metatarsals and the phalanges.
