What you will learn about in this section: The Function of the Skeleton The Name of the Bones The Different Shapes of Bones How Bones Help the Sportsperson Bones Linked With Sporting Actions The Skeleton

Slide 3

What is the skeleton? The Skeleton is a framework of bones that is held together by ligaments and joints. Functions of the Skeleton

Slide 4

The joints of the skeleton, where two or more bones come together, allows some movement depending upon the type of joint and the types of bone. These variations will determine the kind of movement there can be. Movement

Slide 5

The skeleton forms protection around some of the more delicate organs of the body. Eg: the skull protects the brain, the ribs protect the heart and lungs. Protection

Slide 6

Shape The skeleton gives us our general shape; tall, short, broad or narrow. (Look around you and compare your structure)

Slide 7

Support The skeleton provides the body with a rigid structure that gives it its shape. Muscles are attached to the skeletons outside while the vital organs are attached to the inside.

Slide 8

Red and white blood cells are produced in the bone marrow, a substance found inside the larger bones of the body. These are necessary for fighting disease and transporting oxygen around the body. Blood Production

Slide 10

Names of major bones in the skeleton Look at the upper body first (remember the ulna is under the radius)! Lower body (the tibia is on top of the fibula)

Slide 12

axial skeleton appendicular skeleton There are two parts to the skeleton

Slide 13

This consists of: The skull: 8 flat bones that fuse together over time. The vertebral column or spine: 24 movable vertebrae and two groups of fused vertebrae. The rib cage: 12 pairs of ribs (protect vital organs & part of the breathing mechanism ). The Axial Skeleton

Slide 14

Made up from the pelvic girdle and the shoulder girdle. Both these girdles are quite rigid but they are attached to legs and arms that are free to move. The Appendicular Skeleton

Slide 15

The Different Shapes of Bones Type of Bone Example Long Bones Arms, legs, hands (metacarpals), feet (metatarsals), phalanges Short Bones Hands (carpals), feet (tarsals) Flat Bones Skull, shoulder blade, sternum, ribs, pelvis, clavicle (collar bone) Irregular Bones Vertebrae, knee, jaw bone, cheek bone There are four types of bone and each type is given a name dependant of its shape or size.

Slide 16

Long bones; long to create leverage when playing sport. Can you give examples of a sport where long bones would benefit the sports performer? Long bones help to generate speed, force and power. Types of Bones & Sport

Slide 17

Long limbs are an advantage in Volleyball

Slide 18

What other bones are long bones an advantage for? See if you and a partner can list 5 other sports. Basketball, rowing, netball goal shoot/defence, tennis, cricket bowler, boxing. Question

Slide 19

These are tough and are designed to withstand hard impact. In a game of rugby which areas of the body would need to withstand a tackle/fall/scrum? Flat Bones

Slide 20

Short bones; fine movement eg: putting spin on a ball in cricket, these bones help make small adjustments and are very important. Name 2 other sports where fine movements are critical for the success of a particular sport. Short Bones

Slide 21

Irregular bones; act as shock absorbers (especially on the back and the knee). Give an example of a sport where irregular bones are used to assist with the absorption of shock on the body. Irregular Bones
