Name three types of muscles
There are 3 types of muscles, Cardiac (Heart), Skeletal (attaches to our bones), and smooth (digestive).
What are Slow twitch fibres
Slow twitch fibres are used for muscular endurance – they contract slowly but do not fatigue (get tired) easily
Slow twitch fibres are typically red in colour due to the dense supply of capillaries
Slow twitch fibres are prevalent in endurance athletes, such as marathon runners
What are Fast twitch fibres
Fast twitch fibres are used for muscular strength – they contract rapidly but fatigue easily
Fast twitch fibres are typically lighter in colour (white)
Fast twitch fibres are prevalent in strength athletes, such as sprinters
What are the 4 functions of the Skeleton
- Shape and Support
- Movement
- Protection
- Blood Production
What is protection in the skeleton
Internal organs are soft, delicate and easily damaged. These vital organs are protected by the skeleton. An example of this is the cranium protects the heart and the ribs help protect the heart and lungs.
What is movement in the skeleton
Muscles are attached to the skeleton. Movement occurs when muscles contract and pull on bones making them move about joints. For example, the biceps muscle connects the shoulder and the elbow and helps with lifting.
What is shape and support in the skeleton
The skeleton provides shape and support for the body. It forms the frame to which our muscles can attach and in which our organs can sit. An example is the backbone enables us to stay upright.
What is blood production in the skeleton
The centre of some large bones contains red bone marrow, which creates red blood cells. The pelvis and femur are both important in blood production.
What are all the Long bones in the body
Humerus, Ulna, Radius, Femur, Tibia, Fibula, Clavicle, Metacarpals, Phalanges, Metatarsals
What are all the Short bones in the body
Carpals, Patella, Tarsals, Talus
What is the purpose of Long bones
Allow a lot a of movement in the body as well as blood production
