Question 1

What are the 5 functions of the skeletal system?

Answer 1

• Protection of vital organs (e.g)
• Muscle attachment
• Joints for movement
• Storing calcium and phosphorus
• Red and white blood cell production

Question 2

What is the significance of each function of the skeletal system in sport?

Answer 2

• Vital organ protection is required as, if they were damaged, you could potentially find it harder to breathe, think and perform.
• The muscles you use in sport need strong points, to attach to and bons provide that framework.
• Joints allow the body to make a variety of movements from small movements like grabbing to large movements like throwing.
• The bones act as a store for calcium and phosphorus, two minerals that are vital for developing and maintaining the strong and healthy bones you need for exercise.

Question 3

What are the names of the bones in the central body and head and their location?

Answer 3

• Cranium (skull)
• Vertebrae (spine)
• Clavicle (collar)
• Scapula (above lats)
• Sternum (rib cage centre)
• Rib (ribs)
• Pelvis (hip)

Question 4

What are the names of the bones in the limbs and their location?

Answer 4

• Humerus (upper arm)
• Radius (inner lower arm)
• Ulna (outer lower arm)
• Carpals (wrists)
• Metacarpals (lower finger)
• Phalanges (upper finger)
• Femur (upper leg)
• Patella (knee)
• Tarsals (ankle)
• Metatarsals (lower toe)
• Phalanges (upper toe)

Question 5

What are the 4 classifications of bone?

Answer 5

• Long bones
• Short bones
• Flat bones
• Irregular bones

Question 6

What is the use of each classification of bone in sport?

Answer 6

• Long bones are vital to generate movements when muscles attatched pull them, strength and speed
• Short bones are usually associated with weight bearing, shock absorbing and spreading loads.
• Irregular bones form protection for different body areas but also help to generate movement.
• Flatbones protect your organs in contact sports and provide attachment for muscles to help movement.
